Vesicosigmoidal Fistula Caused by Diverticulitis / 대한비뇨기과학회지

ABSTRACT

Enterovesical fistula is a relatively uncommon complication involving colorectal and pelvic malignancies, intestinal diverticulitis, inflammatory bowel disease, radiotherapy and trauma in Asian countries. A 77-year-old male was referred with complaints of difficult urination, frequency, nocturia and abdominal discomfort. On admission, fever and fecaluria were present. Various diagnostic procedures such as excretory urography, cystography, cystoscopy, rectoscopy and pelvic computed tomography (CT) scan were performed. Under the impression of vesicosigmoidal fistula, segmental resection of the sigmoid colon with partial cystectomy was performed. The histopathology revealed diverticulosis of the sigmoid colon with diverticulitis and development of a vesicosigmoidal fistula.
