What are the other Names for this Condition? (Also known as/Synonyms)

• Endometriosis of the Ureter
• Ureter Endometriosis

What is Ureteral Endometriosis? (Definition/Background Information)

• Ureteral Endometriosis is a rare condition where endometrial-like tissue grows within or near the ureters, which are the tubes that carry urine from the kidneys to the bladder. Endometrial tissue in the ureters can cause blockages, scarring, and other complications
• Women in their young to middle adulthood are higher prone to the development of this condition. The risk factors include one’s genetic makeup, retrograde menstruation, hormonal imbalances, and a positive family history of endometriosis. The exact cause of Ureteral Endometriosis is not well understood
• The condition may be diagnosed via imaging studies and ureteroscopy.  Following a diagnosis, Ureteral Endometriosis may be treated using hormonal therapies and surgical interventions. The prognosis of women with the condition is typically improved with early recognition and adequate treatment

Who gets Ureteral Endometriosis? (Age and Sex Distribution)

• Ureteral Endometriosis primarily affects women of reproductive age, typically between their 30s and 40s. However, it can occur in women of any age who have a history of endometriosis
• The condition is observed worldwide, and all racial and ethnic groups are generally at risk

What are the Risk Factors for Ureteral Endometriosis? (Predisposing Factors)

Several risk factors can increase the likelihood of developing Ureteral Endometriosis, including:

• History of endometriosis
• Retrograde menstruation (flow of menstrual blood backward into the fallopian tubes and the pelvis)
• Genetic predisposition
• Hormonal imbalances
• Immune system dysfunction

It is important to note that having a risk factor does not mean that one will get the condition. A risk factor increases one’s chances of getting a condition compared to an individual without the risk factors. Some risk factors are more important than others.

Also, not having a risk factor does not mean that an individual will not get the condition. It is always important to discuss the effect of risk factors with your healthcare provider.

What are the Causes of Ureteral Endometriosis? (Etiology)

The exact cause of Ureteral Endometriosis is not fully understood.

• It is believed to occur due to the retrograde flow of menstrual blood containing endometrial cells into the fallopian tubes and the subsequent spread of these cells to the ureters
• Hormonal and immune system factors may also contribute to the development of endometrial tissue in the ureters

What are the Signs and Symptoms of Ureteral Endometriosis?

The signs and symptoms of Ureteral Endometriosis may vary from one individual to another, depending on the severity of the condition. These may include:

• Flank pain (pain in the side or back)
• Pelvic pain, especially during menstruation
• Blood in the urine (hematuria)
• Urinary frequency or urgency

How is Ureteral Endometriosis Diagnosed?

The diagnosis of Ureteral Endometriosis may involve the following:

• Medical history assessment to identify symptoms and risk factors
• Physical examination to check for tenderness or masses in the pelvic area
• Imaging tests, such as ultrasound, MRI, or CT scan, to visualize the ureters and detect any abnormalities
• Ureteroscopy, a procedure where a thin tube with a camera is inserted into the ureter to directly visualize the ureteral wall and collect tissue samples for biopsy

Many clinical conditions may have similar signs and symptoms. Your healthcare provider may perform additional tests to rule out other clinical conditions to arrive at a definitive diagnosis.

What are the possible Complications of Ureteral Endometriosis?

Ureteral Endometriosis can lead to various complications, including:

• Ureteral obstruction (blockage) leading to kidney damage
• Hydroureter (dilation of the ureter)
• Recurrent urinary tract infections
• Hydronephrosis or enlargement of the kidneys due to urine buildup
• Chronic kidney disease

How is Ureteral Endometriosis Treated?

Treatment options for Ureteral Endometriosis may depend on several factors and can include:

• Surgical intervention: Minimally-invasive techniques, such as laparoscopy or robot-assisted surgery, may be used to remove or excise endometrial tissue from the affected ureter. In severe cases, partial ureteral resection or ureteral reimplantation may be necessary
• Hormonal therapy: Progestins, gonadotropin-releasing hormone (GnRH) agonists, or oral contraceptives may be prescribed to suppress the menstrual cycle and reduce the growth of endometrial tissue
• Pain management: Nonsteroidal anti-inflammatory drugs (NSAIDs) or analgesics may be used to alleviate pain

How can Ureteral Endometriosis be Prevented?

As the exact cause of Ureteral Endometriosis is unknown, specific prevention strategies are presently limited. However, early diagnosis and prompt treatment of endometriosis in other locations may help prevent the progression or spread of the condition to the ureters.

What is the Prognosis of Ureteral Endometriosis? (Outcomes/Resolutions)

• With appropriate treatment and management, many individuals with Ureteral Endometriosis can experience symptom relief and preservation of kidney function
• However, the prognosis may vary depending on the extent of the disease and the individual's response to treatment
