Foreskin reconstruction vs circumcision in distal hypospadias.

Abstract

The purpose of the study was to determine if there were differences in the complication rates between foreskin reconstruction (FR) and circumcision (CIRC) in distal hypospadias repairs. The primary outcomes were urethrocutaneous fistula (UF) and dehiscence. The data of distal hypospadias operated between 2005 and 2013 were retrospectively reviewed. The inclusion criteria were any distal hypospadias repair that required an urethroplasty. The exclusion criteria were follow-up <1year, redo procedures, chordee greater than 20°, and incomplete data. Univariate and multivariate analysis was performed on the results. 213 patients were included (95 FR and 118 CIRC). The 2 groups were comparable for age at surgery 19.32months in FR and 14.25months in CIRC. Mathieu repair was more common in FR (47/95-49.47%) than in CIRC (45/118-38.14%). The total subsequent procedures required were 23 in FR and 57 in CIRC. The incidence of UF was 6.3% (6/95) in FR and 27.1% (32/118) in CIRC (p<0.001, OR 5.52, 95% CI 2.2-13.9). Complete dehiscence rates were 3.16% (3/95) FR vs 11.02% (13/118) for CIRC (p=0.037, OR 3.8, 95% CI 1.05-13.74). The incidence of patients requiring reoperation was 18.9% (18/95) in FR versus 45.8% (54/118) in CIRC (p<0.001, OR 3.61, 95% CI 1.93-6.76). Foreskin Reconstruction conferred a significantly lower rate of complications, particularly the UF rate, dehiscence rate, and number of patients that required reoperation. Our rate of complications in the CIRC group is much higher than other published data.
