Parsiyel Sistektomi Uygulanmiş Bir Primer Mesane Endometriozisi Olgusu

Primary bladder endometriosis is rare. Most cases are secondary to pelvic surgery, such as cesarean section or hysterectomy. In this article, we present a case of primary bladder endometriosis in a 33 year-old female patient who had undergone partial cystectomy. Hematuria which is not related to menstruel cycle, and pelvic pain were initial complaints of the patient. After a transurethral resection at an external center where the patient received definitive diagnosis, complaints of the patient had stood still post-operatively. We have decided to perform an open partial cystectomy after cystoscopic and radiological re-evaluation of the patient in our clinic. A 20 mm diameter solid mass extending out of the bladder was excised at the operation. No endometriotic lesions were detected in pelvic peritoneum or ovaries. At the follow-up, there were no recurrences both at cystoscopy and computerised tomography for 4 months after the surgery. Key words: Endometriosis; Hematuria; Urinary Bladder; Cystectomy.
