ABSTRACT

<p><b>OBJECTIVE</b>To present the experience in using the Snodgrass technique, Duckett repair and bladder mucosa grafting for hypospadias.</p><p><b>METHODS</b>We retrospectively reviewed 251 cases of middle and posterior hypospadias treated by the Snodgrass technique, Duckett repair and bladder mucosa grafting from February 1997 to December 2008.</p><p><b>RESULTS</b>The success rates of the Snodgrass technique, Duckett repair and bladder mucosa grafting were 80.3% (53/66) , 76% (19/25) and 78.9% (15/19) for middle hypospadias and 68. 3% (41/60) , 63.6% (14/22) and 88. 1% (52/59) for the posterior type without statistical significant differences (all P > 0.05). Bladder mucosa grafting showed a significantly higher success rate than the other two procedures in either one-stage or two-stage surgical repair of posterior hypospadias (P < 0.05). Duckett repair achieved a significantly higher rate of success in children under 14 years than in the older ones (P < 0.05).</p><p><b>CONCLUSION</b>Of the three surgical options, bladder mucosa grafting is the most suitable for posterior hypospadias, and Duckett repair is recommended for children under 14 years of age.</p>
