title: Localization of a colovesical fistula using a retrograde guide-wire: report of a case.
abstract: We describe an unconventional method of localizing a colovesical fistula by using a guide-wire, successfully carried out in a 45-year-old man with recurrent dysuria, pneumaturia, and suprapubic tenderness. First, we performed a cystoscopy to establish the fistulous tract in the bladder and passed the guide-wire through it. Next, we performed a colonoscopy, and the guide-wire was identified and brought out through the anus. This created a wire loop through the fistula. The transparietal catheter enabled us to detect the exact fistulous tract at laparotomy, making it possible to resect the inflamed colon and identify and resect the fistulous opening on the vesical wall. This technique allowed for a safer resection and a shorter operation time.
