Entero-neovesical fistula after radical cystectomy and orthotopic ileal neobladder: A report of two cases requiring surgical management

Entero-neovesical fistula is a rare complication after radical cystectomy and orthotopic ileal bladder substitution. Typical presenting symptoms are faecaluria, pneumaturia, recurrent urinary tract infections and abdominal pain. Risk factors include history of pelvic radiation, chemotherapy and abdominal surgery, as well as diverticular colonic disease, inflammatory bowel disease and traumatic pelvic injury. The paucity of cases reported in the literature makes the management of this threatening complication very challenging. Conservative treatment has only anecdotally been reported.
