Surgical Outcome of Different Types of Primary Hypospadias Repair During Three Decades in a Single Center

Abstract

To evaluate the surgical outcome of different techniques of primary hypospadias repair in a single department. We retrospectively evaluated the medical files of all patients who had undergone primary hypospadias repair at our department during the past 3 decades (1978-2009). A total of 820 patients were divided into 3 groups. The first group of 309 patients (37.7%) had glanular hypospadias, the second group of 398 patients (48.5%) had distal hypospadias, and the third group of 113 patients (13.8%) had proximal hypospadias. Of these 820 patients, 67 (8.2%) required corpoplasty to straighten the penis. In the first group, 67 (21.7%) children underwent meatal advancement or meatoplasty, 211 (68.3%) underwent meatal advancement and glanduloplasty, 8 (2.6%) underwent tubularized incised plate hypospadias repair, and 23 (7.4%) underwent Mathieu flap hypospadias repair. In the second group, 196 (49.2%) underwent Mathieu hypospadias repair, 38 (9.5%) underwent tubularized incised plate repair, 142 (35.7%) underwent meatal advancement and glanduloplasty, and 22 (5.5%) underwent onlay-type hypospadias repair. In the third group, 28 (24.8%) underwent 2-stage hypospadias repair, 85 (75.2%) underwent single-stage surgery (including 68 [60.2%] onlay and 11 [9.7%] tubularized island flap), and 6 (5.3%) underwent tubularized incised plate hypospadias repair. Immediate complications developed in 46 (14.9%) in the first, 123 (30.9%) in the second, and 66 (58.4%) in the third group; 38 (4.6%) required additional surgery during or after adolescence. Our data have shown that despite the numerous techniques used for hypospadias surgery, the incidence of complications is still high in patients who undergo hypospadias repair.
