Summary
This case report details an extremely rare instance of bladder endometriosis involving the urachus. The condition mimics urachal carcinoma, emphasizing the need for careful diagnosis and surgical intervention.
Area of Science:
- Urology
- Gynecology
- Pathology
Background:
- Endometriosis is a condition where uterine tissue grows outside the uterus.
- Urachal endometriosis is exceptionally rare, with bladder involvement being even rarer.
- Distinguishing urachal endometriosis from urachal carcinoma is diagnostically challenging due to similar presentations.
Purpose of the Study:
- To report a unique case of bladder endometriosis involving the urachal area.
- To highlight the diagnostic challenges and emphasize the importance of considering this rare condition in differential diagnoses.
- To underscore the necessity of prompt surgical intervention and histopathological confirmation.
Main Methods:
- Case report of a 34-year-old woman with bladder irritative symptoms.
- Diagnostic imaging (unspecified) and cystoscopy.
- Robot-assisted laparoscopic partial cystectomy followed by histopathological analysis.
Main Results:
- Imaging revealed an uncertain mass in the urachal region.
- Cystoscopy indicated bladder compression.
- Postoperative pathology confirmed bladder endometriosis.
Conclusions:
- Bladder endometriosis in the urachal area is exceedingly rare and can mimic urachal carcinoma.
- Differential diagnosis requires high suspicion, especially with relevant clinical symptoms.
- Early surgical management and definitive histopathological diagnosis are crucial for appropriate patient care and preventing disease progression.

The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...

01:23Urinary Bladder

The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
