AIM: There are multiple surgical techniques for distal urethrocutaneous fistulas (DUCF) repair after hypospadias surgery. Our aim was to analyze our results of simple closure (SC) and salvage mathieu urethroplasty (MU).
MATERIAL AND METHODS: Retrospective study (2014-2017) of pediatric patients with DUCF who underwent SC and MU. Only subcoronal to distal fistulas were collected, excluding the proximal ones non-tributary of MU. Demographics, clinical data, treatment and results were registered.
MAIN RESULTS: Over 4 years, 177 hypospadias and 28 UCFs were repaired. 15/28 met the inclusion criteria. Hypospadias type: anterior (10, 66.7%), midshaft (3, 20%) and posterior (2, 13.3%). Mean age at primary urethroplasty was 31.9 months (SD: 16.2). The most common techniques in primary surgery were Thiersch-Duplay (6) and Snodgrass (4). Median time from primary surgery to apparition of the fistula was 5 months (rank: 0-14). The surgical technique used for fistula repair was: SC (7) and MU (8). DUCF succeeded in all patients treated with MU, while among those treated with SC, 71.4% recurred, and only 4 patients underwent finally successful repair with a median of 1.5 interventions. Median follow-up was 25 months (rank: 12-55).
CONCLUSIONS: MU is a useful, effective and safe technique for DUCF repair. Most importantly, it is easily reproducible. The results of MU seem to be superior to CS and could be considered as a first choice.
