Two cases of bladder endometriosis treated using cystoscopy-assisted laparoscopic partial cystectomy

This paper reports two cases of bladder endometriosis in women with longstanding cyclic painful urination and hematuria, investigated using cystoscopy and treated with cystoscopy-assisted laparoscopic partial cystectomy. In case 1, a dark-red polypoid posterior bladder wall lesion was identified, symptoms were treated with GnRH-agonist followed by dienogest with limited improvement, and surgery used cystoscopy to define the incision line with a margin from both ureteral orifices, with no leakage confirmed on postoperative cystography. In case 2, after stopping LEP due to breast cancer and recurrence of menstruation-associated pelvic pain including pain with urination and defecation, cystoscopy again showed a posterior bladder polypoid lesion and the patient underwent laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and cystoscopy-assisted partial cystectomy with an uneventful postoperative course. The major limitation is that this is a small case report series (two patients) without controlled comparison, so findings are descriptive. This paper is centrally about endometriosis — specifically bladder endometriosis treated with cystoscopy-assisted laparoscopic partial cystectomy.
