Bladder endometriosis: report of 7 new cases and review of the literature

OBJECTIVE: To describe our experience with bladder endometriosis at the Department of Urology of Complejo Hospitalario Universitario de Santiago de Compostela. METHODS: We performed a retrospective analysis of the cases of bladder endometriosis diagnosed during the last 11 years in our hospital, from January 2000 to December 2011. RESULTS: A total of 7 women, with a mean age of 32-year-old have been diagnosed by biopsy of bladder endometriosis. The most common symptoms were dysuria, suprapubic pain, urinary urgency and hematuria. All patients have undergone surgery (5 transurethral resection, 2 partial cystectomy), 6 of them were also treated with post-operative LHRH analogues. CONCLUSIONS: Endometriosis is a common disease in young women, but the involvement of the urinary tract is unusual. There are multiple therapeutic options; despite this there exists a high probability of recurrence.
