Abstract: Objective To analyze the diagnosis and treatment of bladder endometriosis. Methods Clinical data about 14 bladder endometriosis patients admitted to our hospital from 2003 to 2013 were retrospectively analyzed. Results The average age of the 14 patients was 40±5.5 years. Their main clinical manifestations were periodical hypogastralgia, urgency and frequency of micturition, urodynia, and periodical gross hematuria. The symptoms were alleviated in 13 patients after laparoscopic partial bladder resection and GnRH-a therapy with no recurrence during the follow-up. Conclusion Diagnosis of bladder endometriosis can be established according to its typical clinical manifestations, ultrasonography, pelvic MRI and cystoscopy fi ndings. Laparoscopy partial cystectomy in combination with GnRH-a therapy is an effective and rational treatment modality for bladder endometriosis.
