Comparative study of two techniques used in distal hypospadias repair: Tubularized incised plate (Snodgrass) and tubularized urethral plate (Duplay)

Abstract

The aim of this study was to compare the results of the tubularized incised plate (the Snodgrass technique) and tubularized urethral plate (the Duplay technique) in distal hypospadias repair. Between April 2000 and September 2008, 245 distal hypospadias was corrected by a single surgeon: 132 patients underwent repair by tubularized incised plate and 113 by tubularized urethral plate. The age of the patients ranged from 16 to 48 months (mean 27 months). Mean follow-up was 84 months (21-120 months). With the tubularized incised plate, the meatus was vertically oriented and expanded to the apex of the glans, and the rate of fistulae formation was low (3%) but that of neourethral stenosis was high (22%). The Duplay technique led to fistulae in nine patients (8%) and stenoses in only eight (7%). The tubularized incised plate gave an excellent cosmetic result with fewer fistulae; however, more stenoses occurred than with the tubularized urethral plate technique.
