ABSTRACT
Background: Colovesical fistula is a rare complication of inflammatory and neoplasic pelvic diseases [0.2%]
Aim: To report a new case
Case: We report the case of a 74-year-old woman, with a charged previous medical history and had not had hysterectomy. She was admitted because of cystitis with haematuria associated to faecaluria and pneumaturia confirmed by an intravenous pyelogram. Water-soluble contrast medium show the sigmoidovesical fistula. A sigoid sticture is identified at colonoscopy and biopsy was realised. The patient had had sigmoidectomy with Hartmann's procedure. Histologic study confirm the diverticulatis with preidiverticular abcess and fistula
We suggest that early diagnosis and management of sigmoid diverticulatis is required to prevent complicatins like stricture and fistula
