Surgical outcome of different types of primary hypospadias repair during three decades in a single center

Abstract

Objective: To evaluate the surgical outcome of different techniques of primary hypospadias repair in a single department.

Methods: 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).

Results: 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.

Conclusion: 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.
