This study evaluates the clinical significance of a radiological leak on pericatheter urethrogram after URF repair as a predictor of success or failure of the surgery. METHODS: 138 URF repairs, mostly resulting as a complication following the treatment of prostate or rectal cancer, were performed between January 2006 and June 2020 in a single reconstructive urology unit. Data were available on 113 of these for analysis. RESULTS: 71 cases (63%) were performed via a transperineal (TP) approach with a gracilis interposition flap in 27 (38%). 42 cases (37%) required additional abdominal exposure. 60 cases (54%) were performed in patients who had undergone radiotherapy, HIFU or cryotherapy. 20 (18%) were redo procedures. All patients had a pericatheter urethrogram at a mean of 31 days (range 21-70d) post-op. 43 (38%) patients had no radiological leak and the catheter removed at the time. 30 (27%) patients demonstrated leakage of contrast directly into the rectum or onto the perineum. Only 4 of these healed by conservative management. All 4 had a TP approach, were unirradiated and fairly uncomplicated URF. The other 26 developed recurrent fistulation. In a further 40 patients (35%), contrast leakage into a blind-ending track (n=24) or contained cavity (n=16) was observed. The catheter was left in situ and a second urethrogram performed on average 24 days later (range 7-93d). In 19, the radiological leak was no longer evident and the catheter removed. The remaining 21 had a third urethrogram at a mean of 32 days later (range 13-91) and in 14 the leak had resolved. The remaining 7 had their catheters eventually removed at an average of 111 days post-op (range 88-180d). Of all 40 patients with a contained leak on initial urethrogram managed conservatively, only 3 showed clinical evidence of fistula recurrence after catheter removal. These were all after abdomino-perineal repairs in irradiated patients. CONCLUSIONS: Radiological evidence of persistent fistula on the first post-operative urethrogram after URF repair is a likely predictor of failure. However, presence of a leak from the urinary side into a contained cavity or a blind-ending track is a relatively common occurence. In most instances this can be managed successfully conservatively without compromising the final outcome.
