What kind of doctor treats Mayer-Rokitansky-Küster-Hauser Syndrome?
A gynecologist, a doctor who treats the female reproductive system, usually leads care for Mayer-Rokitansky-Küster-Hauser syndrome. Kidney doctors and bone surgeons may join the care team. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Mayer-Rokitansky-Küster-Hauser syndrome?
Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a condition that causes the vagina and uterus to be underdeveloped or missing. The uterus is the womb, where a baby grows. Because of this, affected women do not have periods. It affects about 1 in 4,500 female newborns.
MRKH syndrome is often divided into two types. Type 1 affects only the reproductive organs. Type 2 also affects other parts of the body, such as the kidneys, hearing, heart, or spine bones.
Symptoms
Signs can vary from person to person. Common signs include:
- No menstrual periods. This is called primary amenorrhea, which means periods never started. It is often the first sign.
- A short vagina or an underdeveloped uterus.
- Normal breast development and normal growth of body hair.
- Normal outer genitals and working ovaries.
- Trouble or pain with sexual intercourse, because the vagina is short.
In type 2, a person may also have kidney problems, scoliosis (a curved spine), hearing loss, or heart defects.
Causes and who gets it
The cause is unknown. The features come from incomplete growth of the Müllerian duct. This is a structure in the embryo that grows into the uterus, fallopian tubes, cervix, and upper vagina. NORD says MRKH syndrome is not caused by anything the mother did.
Changes in some genes have been found in a few people. MRKH syndrome is the second most common cause of primary amenorrhea. It is present at birth. It is often not found until early teen years.
How doctors diagnose it
Most girls first see a doctor because their periods do not start. The doctor asks questions and does an exam. Some other conditions look similar, so the doctor rules them out.
An ultrasound is usually the first scan. A magnetic resonance imaging (MRI) scan can give more detail. A karyotype is a blood or saliva test that looks at chromosomes. Females with MRKH syndrome have a normal result, called 46,XX. After diagnosis, doctors also check the kidneys and spine. They use an ultrasound and X-rays.
Treatment
Treatment is aimed at the symptoms each person has. It may need a team of specialists. Counseling and support groups are recommended, because the diagnosis can cause anxiety and distress.
To create or lengthen the vagina, vaginal dilators are the first choice in most people. These are specially designed plastic tubes that gently stretch the vagina over time. This should wait until the person is emotionally ready. If dilators do not work, plastic surgery to make a vagina (vaginoplasty) is another option, but surgery has more complications than dilators. ACOG advises seeing a surgeon with experience in this surgery.
A woman with MRKH syndrome cannot carry a pregnancy. Options for having children include a gestational surrogate (another woman who carries the pregnancy) and adoption. Uterus transplant has led to live births, but ACOG considers it experimental because there is limited data. People with only one kidney are watched for urinary infections and kidney stones.
When to see a doctor
See a doctor if periods have not started by age 15, which is often the first sign. Also tell a doctor about belly pain that keeps coming back or does not go away. ACOG notes that belly pain can happen when leftover uterine tissue has an active lining. Anyone who is sexually active should use condoms and get screened for infections.
Call 911 or go to the emergency room for sudden, severe belly or pelvic pain, bleeding that will not stop, fainting, or trouble breathing.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Such a doctor can do a first evaluation and help coordinate the team of specialists that care may need.
Common questions
Can a woman with MRKH syndrome have children?
She cannot carry a pregnancy, but she may still have a biological child with medical help. Some women have used in vitro fertilization, or IVF, with their own eggs. A gestational surrogate then carries the pregnancy. Adoption is another option.
Do the ovaries work normally in MRKH syndrome?
Yes, the ovaries work normally in MRKH syndrome. Girls and women with it also have normal breast and pubic hair development. The problem is in the uterus and vagina.
Does MRKH syndrome run in families?
Usually not. Most cases happen in girls and women with no history of the disorder in their family. Less often it passes through generations. A genetic counselor can talk with you about the chance of passing it on.
Does everyone with MRKH syndrome need surgery?
No, most people do not need surgery. Doctors recommend vaginal dilators as the first treatment in most people. Surgery is kept for the rare person whom dilators do not help, or who prefers surgery.
