Uterus Didelphys: Symptoms and Treatment

Uterus didelphys, also known as a double uterus, is a rare congenital anomaly where a female develops two uteri instead of one. This condition occurs during fetal development when the two Müllerian ducts fail to fuse properly, resulting in two separate uterine cavities, each with its own cervix. 

Uterus didelphys originates during embryonic development. The failure of the Mullerian ducts to fuse correctly leads to the formation of two separate uteri. 

This condition is often associated with other anomalies of the reproductive tract, such as double cervices or vaginal septums. The exact etiology remains unclear, but genetic and environmental factors are believed to play a role.

Genetic Factors

Research indicates that there may be a genetic component to Mullerian duct anomalies. Family history of uterine anomalies can increase the risk, although specific genes responsible for uterus didelphys have not been identified.

Environmental Factors

While less understood, environmental factors during pregnancy could contribute to the development of uterus didelphys. These may include maternal exposure to certain medications or toxins.

Symptoms of Uterus Didelphys

Symptoms of uterus didelphys can vary widely, from being asymptomatic to causing significant reproductive and menstrual issues. Common symptoms include:

Menstrual Irregularities

Women with uterus didelphys often experience irregular menstrual cycles. This may include heavy menstrual bleeding ( menorrhagia) or painful periods ( dysmenorrhea).

Reproductive Challenges

Infertility or recurrent miscarriages can be a significant concern. The presence of two uteri can complicate implantation and the ability to carry a pregnancy to term.

Pelvic Pain

Chronic pelvic pain is another symptom that may occur due to the anatomical abnormalities associated with uterus didelphys.

Abnormal Vaginal Bleeding

Irregular or unexpected vaginal bleeding can occur, often due to the presence of two cervices and potential uterine septums.

Diagnosis of Uterus Didelphys

Diagnosing uterus didelphys often involves a combination of imaging studies and clinical evaluations.

Pelvic Examination

A thorough pelvic examination can reveal the presence of two cervices or a vaginal septum, which may prompt further investigation.

Imaging Studies

Ultrasound

A transvaginal ultrasound is typically the first imaging modality used to evaluate uterine anomalies. It can provide detailed images of the uterine structure.

Magnetic Resonance Imaging (MRI)

MRI offers a more comprehensive view of the pelvic anatomy and can help differentiate between various types of Müllerian duct anomalies.

Hysterosalpingography (HSG)

HSG involves injecting a contrast dye into the uterine cavity and taking X-rays to visualize the internal structure. This can be particularly useful in assessing the shape and size of the uteri and fallopian tubes.

Treatment Options for Uterus Didelphys

The treatment approach for uterus didelphys depends on the severity of symptoms and reproductive goals of the patient.

Surgical Interventions

Metroplasty

In some cases, surgical correction known as metroplasty can be performed to unify the two uteri into a single cavity. This procedure aims to improve reproductive outcomes and alleviate symptoms.

Vaginal Septum Resection

If a vaginal septum is present and causing symptoms, surgical resection may be recommended to remove the septum and create a single vaginal canal.

Reproductive Assistance

For women facing infertility or recurrent miscarriages, assisted reproductive technologies (ART) such as in vitro fertilization (IVF) can be considered. Additionally, close monitoring and specialized obstetric care are crucial for those who conceive naturally.

Symptom Management

Pain management and hormonal therapies may be prescribed to alleviate menstrual irregularities and pelvic pain. This can include the use of nonsteroidal anti-inflammatory drugs (NSAIDs) or hormonal contraceptives.

Uterus Didelphys and Pregnancy

Pregnancy in women with uterus didelphys can be challenging but is possible. However, it carries a higher risk of complications.

Increased Risk of Preterm Birth

The presence of two uteri can limit the space available for fetal growth, increasing the risk of preterm labor and delivery.

Breech Presentation

Babies conceived in a uterus didelphys are more likely to present in a breech position, which can complicate delivery and may necessitate a cesarean section.

Miscarriage

The risk of miscarriage is higher in women with uterus didelphys due to potential issues with implantation and uterine capacity.

Complications Associated with Uterus Didelphys

Complications can arise from both the anatomical abnormalities and the treatments used to manage uterus didelphys.

Endometriosis

Women with uterine anomalies, including uterus didelphys, may have a higher incidence of endometriosis. This condition involves the growth of endometrial tissue outside the uterus, causing pain and fertility issues.

Urinary Tract Anomalies

There is an association between Müllerian duct anomalies and renal abnormalities. Regular monitoring and imaging studies can help identify and manage these issues.

Psychological Impact

The diagnosis and treatment of uterus didelphys can have a significant psychological impact, particularly related to reproductive challenges and chronic pain. Counseling and support groups can be beneficial.
