Leopold's Maneuvers

Leopold's maneuvers

In obstetrics, Leopold's Maneuvers are a common and systematic way to determine the position of a fetus inside the woman's uterus.

Overview and rationale

The maneuvers consist of four distinct actions, each helping to determine the position of the fetus. The maneuvers are important because they help determine the position and presentation of the fetus, which in conjunction with correct assessment of the shape of the maternal pelvis can indicate whether the delivery is going to be complicated, or whether a Cesarean section is necessary.

The examiner's skill and practice in performing the maneuvers are the primary factor in whether the fetal lie is correctly ascertained, and so the maneuvers are not truly diagnostic. Actual position can only be determined by ultrasound performed by a competent technician or professional.

Performing the maneuvers

Leopold's Maneuvers are difficult to perform on obese women and women who have hydramnios. The palpation can sometimes be uncomfortable for the woman if care is not taken to ensure she is relaxed and adequately positioned. To aid in this, the health care provider (or other professional) should first ensure that the woman has recently emptied her bladder. If she has not, she may need to have a straight urinary catheter inserted to empty it if she is unable to micturate herself. The woman should lay on her back with her shoulders raised slightly on a pillow and her knees drawn up a little. Her abdomen should be uncovered, and most women appreciate it if the individual performing the maneuver warms their hands prior to palpation.

First maneuver

While facing the woman, palpate the woman's upper abdomen with both hands. A professional can often determine the size, consistency, shape, and mobility of the form that is felt. The fetal head is hard, firm, round, and moves independently of the trunk while the buttocks feels softer, is symmetric, and has small bony processes; unlike the head, it moves with the trunk.

Second maneuver

After the upper abdomen has been palpated and the form that is found is identified, the individual performing the maneuver attempts to determine the location of the fetal back. Still facing the woman, the health care provider palpates the abdomen with gentle but also deep pressure using the palms of his or her hands. First the right hand remains steady on one side of the abdomen while the left hand explores the right side of the woman's uterus. This is then repeated using the opposite side and hands. The fetal back will feel firm and smooth while fetal extremities (arms, legs, etc.) should feel like small irregularities and protrusions. The fetal back, once determined, should connect with the form found in the upper abdomen and also a mass in the maternal inlet, lower abdomen.

Third maneuver - Pawlick's Grip

In the third maneuver the health care provider attempts to determine what fetal part is lying above the inlet, or lower abdomen. The individual performing the maneuver first grasps the lower portion of the abdomen just above the symphysis pubis with the thumb and fingers of the right hand. This maneuver should yield the opposite information and validate the findings of the first maneauver. If the woman enters labor, this is the part which will most likely come first in a vaginal birth. If it is the head and is not actively engaged in the birthing process, it may be gently pushed back and forth.

Fourth maneuver

The last maneuver requires that the health care provider face the woman's feet, as he or she will attempt to locate the fetus' brow. The fingers of both hands are moved gently down the sides of the uterus toward the pubis. The side where there is the resistance to the descent of the fingers toward the pubis is greatest is where the brow is located. If the head of the fetus is well flexed, it should be on the opposite side from the fetal back. If the fetal head is extended though, the occiput is instead felt and is located on the same side as the back .

Cautions

Leopold's maneuvers are intended to be performed by health care professionals, as they have received training and instruction in how to perform them. That said, as long as care is taken not to roughly or excessively disturb the fetus, there is no real reason it cannot be performed at home as an informational exercise. It is important to note that all findings are not truly diagnostic, and as such ultrasound is required to conclusively determine fetal lie.

The Menstrual Cycle

The Menstrual Cycle

The "typical" menstrual cycle occurs regularly over 28 days. Most women have cycles with an interval that lasts from 21 to 35 days. Frequently cycles are unusually short or long during adolescence.

THE FIRST HALF OF THE MENSTRUAL CYCLE (Day 1 to About Day 14 in a 28-Day Cycle)

The Menstrual Phase

The first day of your menstrual period is considered Day 1 of your cycle. The menstrual phase includes your period. During this time, the endometrium (the built-up lining of the uterus) is shed, along with a little blood. Many of the problems that women experience with their menstrual cycle occur during this phase. For example, some women experience menstrual disorders such as dysmenorrhea (painful periods) or menorrhagia (unusually heavy periods).

The Follicular/Proliferate Phase

During the proliferate phase, the body produces a hormone called follicle-stimulating hormone (FSH). Follicle-stimulating hormone promotes the growth of a follicle (egg sac) within the ovary. An ovum (egg) matures in the follicle during the proliferative phase. FSH also stimulates the ovary to produce increasing amounts of estrogen. In turn, the estrogen causes endometrial tissue to build up (or proliferate), lining the interior of the uterus.

THE MIDPOINT OF THE MENSTRUAL CYCLE (About Day 14 in a 28-Day Cycle)

The mature ovum bursts from the follicle about midway (approximately 2 weeks before onset of next menstrual period) through the menstrual cycle. This process is known as ovulation. The ovum then travels from the ovary down the fallopian tube, and into the uterus.

The Luteal/Secretory Phase

Once the ovum has been released, the follicle becomes a sac known as the corpus luteum ("yellow body," because it contains yellowish, fatty matter). A hormone called luteinizing hormone (LH) causes the corpus luteum to grow and to secrete progesterone, another female hormone.

During the secretory phase, progesterone makes the endometrial lining stronger and spongy in texture. Progesterone also stimulates glands in the endometrium. These glands produce uterine fluid, and their purpose is to support embryonic development if fertilization has occurred at or around the time of ovulation. It is in this phase of the menstrual cycle that women who suffer from premenstrual syndrome (PMS) may begin to experience their symptoms. Generally symptoms are worse during the last seven to ten days of the cycle, ending at or soon after the start of the menstrual period. In a woman who hasn't become pregnant, the level of progesterone peaks about a week after ovulation and then begins to drop along with the estrogen level. The flow of blood to the endometrium decreases, and its upper portion is broken down and shed during menstruation. At the same time, the corpus luteum withers.

The dip in estrogen and progesterone at the end of the cycle help let the body know that it's time to start the cycle all over again. The menstrual cycle doesn't have to be a drag, it actually shows how complex your body is and a sign that it is functioning properly! Congratulations, you are a woman and being a woman is terrific!

What You Need To Know About Menstruation

What You Need To Know About Menstruation

If you're a teenage girl you probably have started having a period. If you have not, you might be anxious about the subject or a bit concerned. This whole menstruation thing might seem a bit mysterious, it is to many young women. It's actually very complex, but interesting too.

Menstruation is the outward proof that a girl is becoming a woman. Having a period is your body's way of saying it’s functioning properly.

During puberty, hormones are released from the brain that stimulate the ovaries. The ovaries then produce estrogen and progesterone -- hormones that cause the eggs in the ovaries to mature so the woman can become pregnant when she chooses to. Here's how the process goes:

Every month, one egg leaves one of the ovaries on its way to the uterus via the fallopian tubes. Meanwhile, in preparation for the egg, the uterus starts to develop a thicker lining and it’s walls become cushiony (the endometrial lining). If the egg reaches the uterus and is fertilized by a sperm cell, it attaches to this cushiony wall.

Most of the time the egg just passes right through without fertilization. Since the uterus no longer needs the extra blood and tissue which made up the walls thick, it sheds them by way of the vagina. This cycle will happen nearly every month until the ovaries stop releasing eggs, usually several decades later. (Menopause).

Periods are different for every woman. Some girls start menstruation when they're 9 or 10; some in their late teens. The length of the cycle also varies. Some periods last longer than 28 days, some shorter. If you have just begun your menstruation, your body will need time to regulate itself to these changes. Your periods might be a bit erratic at first. You may have two cycles in one month and miss having one the next month. How long your period lasts also varies . Some girls have their periods for only 3 or 4 days, others as long as a week. The menstrual flow of blood can vary from woman to woman also.

Some girls may have body and or mood changes around the time of their period. Menstrual cramps are pretty common during the first few days of your period. These are most likely caused by prostagladins. Prostaglandins causes the muscles of the uterus to contract. These cramps tend to become less uncomfortable and sometimes even disappear completely as a girl gets older. Over-the-counter pain medication like ibuprofen or acetaminophen can often give relief; if not, a health care provider can help. If your cramps are very severe, see a gynecologist.

As your period approaches, you may experience premenstrual syndrome (PMS). You may find your emotions amplified during this time. Many women get depressed, irritated, angry, and others cry more than usual or get cravings for certain foods. PMS may be related to changes in hormones. Hormone levels rise and fall during a menstrual cycle, affecting the way a female feels both mentally and physically.

Emotions can become more intense than usual, and many women may feel bloated because of water retention. When your period begins, PMS usually goes away. You may also have acne flare-ups.

Periods are a complex part of puberty, but also your body's way of telling you it is functioning properly and you have taken good care of it. You can still exercise, swim and do everything you enjoy. If you have any questions about periods, ask a parent, health teacher, health care provider, or nurse. You can also ask friends or sisters who have already had their periods. In time you will see that periods are a normal and routine part of your life.

MCN Notes on Umbilical Cord Prolapse

Umbilical Cord Prolapse

What is the umbilical cord?

The umbilical cord is a flexible, tube-like structure that, during pregnancy, connects the fetus to the mother. The umbilical cord is the baby’s lifeline to the mother. It transports nutrients to the baby and also carries away the baby’s waste products. It is made up of three blood vessels – two arteries and one vein.


What is umbilical cord prolapse?

Umbilical cord prolapse is a complication that occurs prior to or during delivery of the baby. In a prolapse, the umbilical cord drops (prolapses) through the open cervix into the vagina ahead of the baby. The cord can then become trapped against the baby’s body during delivery. Umbilical cord prolapse occurs in approximately one in every 300 births.

What causes an umbilical cord prolapse?

The most common cause of an umbilical cord prolapse is a premature rupture of the membranes that contain the amniotic fluid. Other causes include:
• Premature delivery of the baby
• Delivering more than one baby per pregnancy (twins, triplets, etc.)
• Excessive amniotic fluid
• Breech delivery (the baby comes through the birth canal feet first)
• An umbilical cord that is longer than usual

What are the consequences of umbilical cord prolapse?

An umbilical cord prolapse presents a great danger to the fetus. During the delivery, the fetus can put stress on the cord. This can result in a loss of oxygen to the fetus, and may even result in a stillbirth.

How is an umbilical cord prolapse detected?

The doctor can diagnose a prolapsed umbilical cord in several ways. During delivery, the doctor will use a fetal heart monitor to measure the baby’s heart rate. If the umbilical cord has prolapsed, the baby may have bradycardia (a heart rate of less than 120 beats per minute). The doctor can also conduct a pelvic examination and may see the prolapsed cord, or palpate (feel) the cord with his or her fingers.

How is an umbilical cord prolapse managed?

Because of the risk of lack of oxygen to the fetus, an umbilical cord prolapse must be dealt with immediately. If the doctor finds a prolapsed cord, he or she can move the fetus away from the cord in order to reduce the risk of oxygen loss.
In some cases, the baby will have to be delivered immediately by cesarean section. If the problem with the prolapsed cord can be solved immediately, there may be no permanent injury. However, the longer the delay, the greater the chance of problems (such as brain damage or death) for the baby.

Hydatidiform mole

Definition

A hydatidiform mole is a rare mass or growth that may form inside the uterus at the beginning of a pregnancy. See also choriocarcinoma.

Alternative Names

Hydatid mole; Molar pregnancy

Causes

A hydatidiform mole results from over-production of the tissue that is supposed to develop into the placenta. The placenta normally nourishes a fetus during pregnancy. Instead, these tissues develop into a mass. The mass is usually made up of placental material that grows uncontrolled. Often, there is no fetus at all.
The cause is not completely understood. Potential causes may include defects in the egg, abnormalities within the uterus, or nutritional deficiencies. Women under 20 or over 40 years of age have a higher risk. Other risk factors include diets low in protein, folic acid, and carotene.

Symptoms

• Vaginal bleeding in pregnancy during the first trimester
• Nausea and vomiting, severe enough to require hospitalization in 10% of cases
• An abnormal growth in the size of the uterus, for the stage of the pregnancy
o Excessive growth in approximately 1/2 of cases
o Smaller-than-expected growth in approximately 1/3 of cases
• Symptoms of hyperthyroidism:
o Rapid heart rate
o Restlessness, nervousness
o Heat intolerance
o Unexplained weight loss
o Loose stools
o Trembling hands
o Skin warmer and more moist than usual
• Symptoms similiar to preeclampsia that occur in the 1st trimester or early in the 2nd trimester. (This almost always indicates hydatidiform mole, because preeclampsia is extremely rare this early in normal pregnancies.)
o High blood pressure
o Swelling in feet, ankles, legs
o Proteinuria

Note: All symptoms occur in conjunction with a potential, suspected, or confirmed pregnancy.

Exams and Tests

A pelvic examination may show signs similar to a normal pregnancy, but the uterine size may be abnormal and fetal heart tones are absent. Additionally, some bleeding may be noted.

Tests typically include:
• Measurement of serum HCG to confirm pregnancy. Repeated HCG measurements can be used to monitor the rate and consistency of decline if a hydatidiform mole is suspected.
• An ultrasound of the pelvis.
• A chest X-ray and abdominal CT or MRI will be recommended for some patients.

This disease may also alter the results of the following tests:
• Transvaginal ultrasound
• HCG (quantitative)

Treatment

If a miscarriage does not occur and the diagnosis is confirmed, a therapeutic abortion is performed by suction curettage (D and C).
Following either case, serum HCG levels are monitored to assure they return to a normal, non-pregnant level. A hysterectomy may be an option for older women who do not desire future pregnancies.

Outlook (Prognosis)

More than 80% of hydatidiform moles are benign (non-cancerous). The outcome after treatment is usually excellent. Close follow-up is essential. Highly effective means of contraception are recommended to avoid pregnancy for at least 6-12 months.
In 10-15% of cases, hydatidiform moles may develop into invasive moles. These may intrude so far into the uterine wall that hemorrhage or other complications develop.
In 2-3% of cases, hydatidiform moles may develop into choriocarcinoma, which is a malignant, rapidly growing, and metastatic (spreading) form of cancer. Despite these factors, which normally indicate a poor prognosis, the rate of cure after treatment with chemotherapy is high.
Over 90% of women with malignant, non-spreading cancer are able to survive and retain their ability to have children. In those with metastatic (spreading) cancer, remission remains at 75-85%, although the ability to have children is usually lost.

Possible Complications

Lung insufficiency may develop after evacuation of the uterus in cases where the uterus enlarges to greater than 16 weeks gestational size.

When to Contact a Medical Professional

Call your obstetrician if you suspect a hydatidiform mole.
If you have symptoms suggestive of preeclampsia -- such as severe swelling in the legs and feet, abdominal pain and high blood pressure -- see your health care provider immediately, call 911, or get to the emergency room. This can rapidly become a life-threatening emergency.

MCN Notes on Preeclampsia and Eclampsia

Preeclampsia and Eclampsia

What is preeclampsia?

Also referred to as toxemia, preeclampsia is a condition that pregnant women can get and is marked by three specific symptoms: water retention (with swelling particularly in the face and hands), high blood pressure and protein in the urine.
Preeclampsia, when present, usually appears during the second half of pregnancy, usually after the 20th week, but can appear as early as the fifth month.

What is eclampsia?

Eclampsia is the final and most severe phase of preeclampsia and occurs when preeclampsia is left untreated. In addition to the previously mentioned symptoms, women with eclampsia have seizures. Eclampsia can cause coma and even death of the mother and baby and can occur before, during or after childbirth.

What causes preeclampsia and eclampsia?

The exact causes of preeclampsia and eclampsia are not known, although some researchers suspect poor nutrition, high body fat or insufficient blood flow to the uterus as possible causes.

Who is at risk for preeclampsia?

Preeclampsia is most often seen in first-time pregnancies and in pregnant teens and women over 40. Other risk factors include:
• A history of chronic high blood pressure or "hypertension"
• Previous history of preeclampsia
• Obesity prior to pregnancy
• Carrying more than one baby
• History of diabetes, kidney disease, lupus or rheumatoid arthritis

How can I tell if I have preeclampsia?

In addition to swelling, protein in the urine, and high blood pressure, symptoms of preeclampsia can include:
• Rapid weight gain caused by a significant increase in bodily fluid
• Abdominal pain
• Severe headaches
• A change in reflexes
• Reduced output of urine or no urine
• Blood in the urine
• Dizziness or visual disturbances
• Excessive vomiting and nausea

Does swelling during pregnancy mean I have preeclampsia?

Some swelling is normal during pregnancy. However, if the swelling doesn’t go away and is accompanied by some of the above symptoms, be sure to see your doctor right away.

How can preeclampsia affect my baby?

Preeclampsia can prevent the placenta from receiving enough blood, which can cause your baby to be born very small. It is also one of the leading causes of premature births and the difficulties that can accompany them, including learning disabilities, epilepsy, cerebral palsy, and hearing and vision problems.

How is preeclampsia and eclampsia treated?

The only real cure for preeclampsia and eclampsia is the birth of the baby. If the baby is pre-term, the condition can be managed until your baby can be safely delivered. Your health care provider may prescribe bed rest, hospitalization or medication to prolong the pregnancy and increase your unborn baby’s chances of survival. If your baby is close to term, labor may be induced.

MCN Notes on Placenta Previa

Placenta Previa

What is placenta previa?

Placenta previa is a condition in which the placenta (the organ that connects the developing fetus to the mother’s uterus) lies low in the uterus. The placenta might partly or completely cover the cervix. The condition might cause vaginal bleeding. Placenta previa is a serious condition that requires prompt care.

What causes placenta previa?

The cause of placenta previa is unknown. The condition is more common among women who smoke, use cocaine, or are over 35. It occurs far more frequently in women having their second or later babies than in first pregnancies. Women also are at increased risk if they have had previous uterine surgery, including a c-section, a D&C (dilation and curettage), or an abortion. Being pregnant with twins (or a higher number of multiples) is another risk factor for placenta previa. There is a four to eight percent chance of a recurrence in women who have had a placenta previa in a previous pregnancy.

What are the symptoms of placenta previa?

Painless vaginal bleeding is the primary symptom of placenta previa. Bleeding might be heavy or light, and it might occur at the end of the second trimester or the beginning of the third trimester. Additional symptoms of placenta previa can include low blood pressure, shortness of breath, anemia, pale skin, and a weak pulse.
How is placenta previa diagnosed?
A health care provider will perform a physical exam and a complete medical history to diagnose placenta previa. In addition, an ultrasound can be used to confirm the diagnosis.

How is placenta previa treated?

A woman with placenta previa might need to stay in the hospital until delivery. If the bleeding stops, as it often does, her doctor will continue to monitor her and her baby. A pregnant woman will probably be treated with a corticosteroid drug if she is likely to deliver before 34 weeks.
If the bleeding does not stop, or if the woman goes into labor, her health care provider will probably recommend a prompt c-section. Cesarean delivery is recommended for nearly all women with placenta previa because c-sections usually can prevent severe bleeding.

MCN Notes on Ectopic Pregnancy

Ectopic Pregnancy

What is an ectopic pregnancy?

An ectopic pregnancy occurs when the embryo does not implant in the uterus. In many cases of ectopic pregnancy, the embryo implants in one of the fallopian tubes. In rare cases, the embryo attaches to an ovary or other abdominal organs.
Ectopic pregnancy is a potentially life-threatening condition and requires prompt treatment. It usually is discovered by the eighth week of pregnancy.

What causes an ectopic pregnancy?

In most cases, an ectopic pregnancy is caused by conditions that slow down or block the movement of the egg down the fallopian tube and into the uterus. Certain risk factors exist for ectopic pregnancy. A risk factor is a trait or behavior that increases a person’s chance of developing a disease or predisposes a person to a certain condition. Risk factors for ectopic pregnancy include:
•Use of an intrauterine device (IUD), a form of birth control, at the time of conception
•History of pelvic inflammatory disease (PID)
•Sexually-transmitted diseases such as chlamydia and gonorrhea
•Congenital abnormality of the fallopian tube
•History of pelvic surgery — Scarring might block the fertilized egg from leaving the fallopian tube.
•History of ectopic pregnancy
•Tubal ligation (surgical sterilization), unsuccessful tubal ligation, or reversal of tubal ligation
•Use of fertility drugs
•Infertility treatments such as in vitro fertilization (IVF) or gamete intrafallopian transfer (GIFT)

What are the symptoms of an ectopic pregnancy?

Common symptoms of an ectopic pregnancy include:
•Vaginal bleeding
•Signs of early pregnancy
•Lower abdominal or pelvic pain
•Dizziness or weakness

If the fallopian tube ruptures, the pain and bleeding could be severe enough to cause fainting. Contact your health care provider if you are experiencing any of the above symptoms.

How is an ectopic pregnancy diagnosed?

A health care provider will perform a pregnancy test, a pelvic exam, and an ultrasound test to view the condition of the uterus and fallopian tubes.
How is an ectopic pregnancy treated?
In some cases, medicine might be used to stop the growth of pregnancy tissue. If there is a ruptured fallopian tube, emergency surgery might be necessary to stop the bleeding. A laparotomy (a procedure during which an incision is made in the abdomen and the embryonic tissue is removed) might be needed if the embryo is large or blood loss is considered life-threatening. Laparoscopic surgery (minimally invasive surgery) might be appropriate if the fallopian tube is not ruptured and the pregnancy has not progressed very far. In some cases, the fallopian tube and ovary might be damaged and have to be removed, depending on the progression of the pregnancy. Most women who have had an ectopic pregnancy can go on to have subsequent normal pregnancies and births. Discuss the timing of your next pregnancy with your health care provider.

Can an ectopic pregnancy be prevented?

Ectopic pregnancy cannot be prevented. However, treatment of any risk factors the mother might have can improve the chances for a successful pregnancy

MCN Notes on Uterine Prolapse

Uterine Prolapse

What is uterine prolapse?
Uterine prolapse is a condition in which a woman's uterus (womb) sags or slips out of its normal position. The uterus may slip enough that it drops partway into the vagina (birth canal), creating a lump or bulge. This is called incomplete prolapse. In a more severe case--called complete prolapse--the uterus slips so far out of place that some of the tissue drops outside of the vagina.

What are the symptoms of uterine prolapse?
Women with mild cases of uterine prolapse may have no obvious symptoms. However, as the uterus slips further out of position, it can place pressure on other pelvic organs--such as the bladder or bowel--causing a variety of symptoms, including:

  • A feeling of heaviness or pressure in the pelvis
  • Pain in the pelvis, abdomen or lower back
  • Pain during intercourse
  • A protrusion of tissue from the opening of the vagina
  • Recurrent bladder infections
  • Unusual or excessive discharge from the vagina
  • Constipation
  • Difficulty with urination, including involuntary loss of urine (incontinence), or urinary frequency or urgency

Symptoms may be worsened by prolonged standing or walking. This is due to the added pressure placed on the pelvic muscles by gravity.

What causes uterine prolapse?
The uterus is held in place within the pelvis by a group of muscles and ligaments. As these structures weaken, they become unable to hold the uterus in position, and it begins to sag. There are several factors that may contribute to the weakening of the pelvic muscles, including:

  • Loss of muscle tone as the result of aging
  • Injury during childbirth, especially if the woman has had many babies or large babies (more than 9 pounds)
  • Other factors (Obesity, chronic coughing or straining and chronic constipation all place added tension on the pelvic muscles, and may contribute to the development of uterine prolapse.)

Who gets uterine prolapse?
Uterine prolapse most often occurs in women who have had more than one baby through normal vaginal delivery and in post-menopausal women. Menopause occurs when a woman's ovaries stop producing the hormones that regulate her monthly menstrual cycle, and she stops having regular menstrual periods. One of these hormones, estrogen, helps keep the pelvic muscles strong.

How common is uterine prolapse?
Uterine prolapse is fairly common, and the risk of developing the condition increases with age.

How is uterine prolapse diagnosed?
The doctor will perform a pelvic examination to determine if the uterus has lowered from its normal position. During a pelvic exam, the doctor inserts a speculum (an instrument that lets the clinician see inside the vagina) and examines the vagina and uterus. The doctor will feel for any bulges caused by the uterus protruding into the vaginal canal.

How is uterine prolapse treated?
There are surgical and non-surgical options for treating uterine prolapse. The treatment chosen will depend on the severity of the condition, as well as the woman's general health, age and desire to have children. Treatment generally is effective for most women. Treatment options include the following:

Non-surgical options

Exercise -- Special exercises, called Kegel exercises, can help strengthen the pelvic floor muscles. This may be the only treatment needed in mild cases of uterine prolapse. To do Kegel exercises, tighten your pelvic muscles as if you are trying to hold back urine. Hold the muscles tight for a few seconds and then release. Repeat 10 times. You may do these exercises anywhere and at any time (up to four times a day).

Vaginal pessary -- A pessary is a rubber or plastic doughnut-shaped device that fits around or under the lower part of the uterus (cervix), helping to prop up the uterus and hold it in place. A health care provider will fit and insert the pessary, which must be cleaned frequently and removed before sex.

Estrogen replacement therapy (ERT) -- Taking estrogen may help to limit further weakness of the muscles and other connective tissues that support the uterus. However, there are some drawbacks to taking estrogen, such as an increased risk of blood clots, gallbladder disease and breast cancer. The decision to use ERT must be made with your doctor after carefully weighing all of the risks and benefits.

Surgical options

Hysterectomy -- Uterine prolapse may be treated by removing the uterus in a surgical procedure called hysterectomy. This may be done through an incision made in the vagina (vaginal hysterectomy) or through the abdomen (abdominal hysterectomy). Hysterectomy is major surgery, and removing the uterus means pregnancy is no longer possible.

Uterine suspension -- This procedure involves putting the uterus back into its normal position. This may be done by reattaching the pelvic ligaments to the lower part of the uterus to hold it in place. Another technique uses a special material that acts like a sling to support the uterus in its proper position. Recent advances include performing this with minimally invasive techniques and laparoscopically (through small band aid sized incisions) that decrease post operative pain and speed recovery.

What are the complications of uterine prolapse?
Left untreated, uterine prolapse can interfere with bowel, bladder and sexual functions.

Can uterine prolapse be prevented?
It may not be possible to prevent all cases of uterine prolapse, but there are steps that can be taken to help reduce the risk:

  • Maintain a healthy body weight.
  • Exercise regularly (for 20 to 30 minutes, three to five times per week), including Kegel exercises, which may be done up to four times a day. Be sure to check with your health care provider before starting any new exercise program.
  • Eat a healthy diet balanced in protein, fat and carbohydrates. For example, eat at least 5 to 9 servings of fruits and vegetables per day. Also, eat food that is high in dietary fiber (such as whole grain cereals, legumes and vegetables), and minimize your daily fat intake to 25 to 30 grams. Using the Food Guide Pyramid (visit the web site: mypyramid.gov) is a good way to help ensure that you are meeting your nutrition needs. A healthy diet can help maintain weight and prevent constipation.
  • Stop smoking. This reduces the risk of developing a chronic cough, which can put extra strain on the pelvic muscles.
  • Consider estrogen replacement therapy after menopause.
  • Use correct lifting techniques.

Proper techniques for lifting

  • Do not try to lift objects that are awkward or too heavy for you to lift alone. Also, avoid lifting heavy objects above waist level.
  • Before you lift an object, make sure you have firm footing.
  • To pick up an object that is lower than the level of your waist, keep your back straight, and bend at your knees and hips. Do not bend forward at the waist with your knees straight.
  • Stand with a wide stance close to the object you are trying to pick up, and keep your feet firm on the ground. Tighten your stomach muscles and lift the object using your leg muscles. Straighten your knees in a steady motion. Do not jerk the object up to your body.
  • Stand completely upright without twisting. Always move your feet forward when lifting an object.
  • If you are lifting an object from a table, slide it to the edge to the table so that you can hold it close to your body. Bend your knees so that you are close to the object. Use your legs to lift the object and come to a standing position.
  • Hold packages close to your body with your arms bent. Keep your stomach muscles tight. Take small steps and go slowly.
  • To lower the object, place your feet as you did to lift, tighten stomach muscles and bend your hips and knees.
