Split prepuce in situ onlay hypospadias repair: 17 years of experience.
OBJECTIVE
We report our 17-year experience using split prepuce in situ onlay hypospadias repair, including long-term followup of the first 100 patients initially reported on in 1998.


METHODS
We identified 421 patients who underwent in situ onlay repair. Charts were retrospectively reviewed to determine preoperative management, intraoperative details and complications.


RESULTS
In situ onlay repair was used to repair glanular hypospadias in 22 cases (5.2%), coronal hypospadias in 184 (43.7%), distal shaft hypospadias in 152 (36.1%), mid shaft hypospadias in 51 (12.1%), proximal shaft hypospadias in 7 (1.6%) and hypospadias in the penoscrotal region in 5 (1.2%). Repair was successful with 1 procedure in 376 patients (89.4%), which increased to 99.8% after a second procedure. Complications were defined as any problem that gave the surgeon or family reason for concern. Functional complications requiring reoperation occurred in 45 patients (10.6%). Minor complications requiring simple procedures or early postoperative evaluation occurred in 17 patients (4%). Concerns not requiring intervention occurred in 27 patients (6.4%). There were no urethral strictures. Three patients (0.7%) were lost to followup. Repair is pending in 1 patient.


CONCLUSIONS
In situ onlay repair preserves the urethral plate and allows the formation of a well vascularized flap with adequate tissue to completely cover the neourethra, resulting in a low rate of major complications. With longer followup, inclusion of more mid shaft repairs and expansion to more proximal degrees of hypospadias our complication rates are higher than previously reported but there have been no urethral strictures in 17 years of experience. Since complications present at a median of 158 days (mean 570) after the procedure, long-term followup is indicated.
