Abstract:
Hypospadias can be repaired in the majority cases in 1-stage with a high success rate. We reviewed clinical experience of 50 patients who underwent primary hypospadias repair by 1 surgeon using 1-stage repairs except 3 cases in a 30-month period. The results were 1). The half of patients were younger than 5 years (48%). 2). A total of 34 cases (68.0%) had an associated ventral curvature. The dorsal tunica albuginea plication to correct intrinsic curvature was done in 21 cases (61.8%) and dividing the urethral plate in only 3 cases (8.8%). 3). Associated anomalies were cryptorchidism in 7, hydrocele in 3 and severe penoscrotal transposition in 8 cases. 4). 19 cases of anterior hypospadias were repaired by meatoplasty using Heineke-Mikulicz tissue rearrangement (9 cases), MAGPI (3 cases), pyramid procedure (4 cases), Mathieu urethroplasty (2 cases) and onlay island flap (1 case). Of the 31 cases of middle and posterior hypospadias onlay island flap repair was performed in 24 cases (77.4%). 5). The success rates in anterior, middle and posterior hypospadias were 94.7, 64.7 and 42.9%, respectively. The overall success rate was 70%. 6). The most commonly used procedure was onlay island flap urethroplasty. Only 14 of 25 cases (56.0%) were successful with this method but the last 8 cases were repaired with no complications. 7). The most common complications were urethrocutaneous fistula (11 cases) and meatal retraction (3 cases). The complications were managed by rotational advancement flap (11 cases), meatal based flap (2 cases) and urethral advancement (1 case) and the success rate was 73.3%. In conclusion, to achieve more satisfactory results the choice of operation depends on the configuration of either glans or meatus, presence or absence of chordee and status of ventral penile skin in anterior hypospadias. Although the 2-stage repair remains a safe and reliable alternatives for severe hypospadias 1-stage repair was more useful except severe hypospadias combined with penoscrotal transposition."
