Tubularized incised plate urethroplasty: Expanded use in primary and repeat surgery for hypospadias

Purpose: We evaluated the impact of tubularized incised plate urethroplasty on primary and repeat hypospadias repair. Materials and Methods: We retrospectively reviewed the medical records of a ll boys who underwent hypospadias repair at our institution during a recent 3-year period. The level of the hypospadias defect, technique of repair, p rimary repair versus reoperation, age at surgery and complications were rec orded. Results: A total of 520 hypospadias repairs were done from May 1996 through June 1999. We began to perform tubularized incised plate urethroplasty in November 1996. During the ensuing consecutive 32 months 181 primary and 25 repeat hypospadias repairs were done using this technique. Mean patient age at surgery was 22 months (range 3 months to 30 years). During the 6 months immediately before we began to use this method the Mathieu flip-flap proce dure was the most commonly performed technique, accounting for 38% of all h ypospadias repairs. In contrast, during the last 6 months reviewed tubulari zed incised plate urethroplasty accounted for 63% of all repairs, including 41 of 65 primary operations (63%) and 4 of 6 reoperations (67%), while no Mathieu procedures were performed. Postoperative followup was 6 to 38 month s for tubularized incised plate repair. Overall meatal stenosis and a ureth rocutaneous fistula developed in 1 and 14 boys, respectively (7% complicati on rate). Conclusions: Tubularized incised plate urethroplasty has become the preferr ed technique of primary and repeat hypospadias repair at our institution. T he technique has few complications as well as proved success and versatilit y that continues to expand its applicability and popularity.
