This case report details the management of a 38-year-old female with bladder endometriosis and concurrent ureteral involvement, presenting with pelvic pain and voiding difficulties. Following imaging that identified a three-centimeter intracavitary bladder mass, the patient underwent a staged treatment protocol involving laparoscopic partial cystectomy, temporary ureteric stenting, and subsequent medical therapy with dienogest. The approach resulted in significant lesion reduction and complete symptom resolution, demonstrating that combining surgical resection with hormonal suppression can effectively manage complex urinary tract endometriosis while minimizing morbidity. This paper is centrally about endometriosis — specifically focusing on the diagnostic and therapeutic challenges associated with bladder and ureteral involvement within the broader context of deep infiltrative disease.

Abstract

Background: Urinary tract endometriosis (UTE) is the presence of endometriotic implants in the bladder,ureter, kidneys, or urethra. It affects ~1% of women with endometriosis and occurs more commonlyamong those with deep infiltrative endometriosis. Bladder endometriosis is the most commonpresentation, comprising 85% of cases. Concomitant involvement of the bladder and ureter is rare,comprising 1.4% of all cases. The clinical presentation involves lower urinary tract symptoms, thatworsen during menses. Timely diagnosis and treatment are crucial in ameliorating symptoms andpreventing complications, such as obstructive nephropathy. This is a case of bladder endometriosis withureteral involvement, outlining management challenges, reviewing evidence on managementapproaches, and highlighting the experience gained from this case in managing complex UTE.Case presentation: A 38-year-old female presented with a longstanding history of pelvic pain, dysuria,and new-onset voiding difficulty. She had undergone two prior surgical procedures for endometriosis,including a total abdominal hysterectomy. Her physical examination was normal. Ultrasound revealed a3-cm intracavitary bladder mass, which was described as likely endometriosis on magnetic resonanceimaging. On cystoscopy the mass was noted to be larger, encasing the left ureteric meatus. Alaparoscopic cystostomy was performed, with partial resection of the mass and placement of a temporaryureteric stent. After three months of medical treatment with dienogest, cystoscopy revealed a significantreduction in size with sub-centimeter residual avascular tissue. This was resected avoiding the ureter andureteric meatus. A new ureteric stent was placed. A repeat cystoscopy three months later revealed goodhealing with no residual endometriosis. The stent was removed, and a retrograde pyelogram confirmedno meatal stenosis or ureteric obstruction. She has remained symptom-free.Conclusion: Medical and surgical options are available for bladder endometriosis, with partialcystectomy being the gold standard. The initial approach is dependent on the size of the lesion and theextent of ureteric involvement. A staged approach that combines medical or surgical management canensure optimal outcomes while reducing surgery-associated morbidity in complex cases.

Timely diagnosis and treatment are crucial in ameliorating symptoms and preventing complications, such as obstructive nephropathy. This is a case of bladder endometriosis with ureteral involvement, outlining management challenges, reviewing evidence on management approaches, and highlighting the experience gained from this case in managing complex UTE. Case presentation: A 38-year-old female presented with a longstanding history of pelvic pain, dysuria, and new-onset voiding difficulty.

Conclusion

Medical and surgical options are available for bladder endometriosis, with partial cystectomy being the gold standard. The initial approach is dependent on the size of the lesion and the extent of ureteric involvement. A staged approach that combines medical or surgical management can ensure optimal outcomes while reducing surgery-associated morbidity in complex cases.
