ABSTRACT
<p><b>OBJECTIVE</b>To increase the success rate of surgical treatment in patients with hypospadias.</p><p><b>METHODS</b>220 cases of hypospadias underwent one-stage urethra plasty. After the penis was straightened, urethra plasty was performed with pediculated preputial entoplastron (Duckett's method) in 195 cases; with combination of scrotal septum and pediculated preputial entoplastron in 20 cases; with free bladder mucosa transplantation in 2 cases. The self-made dual silastic tubes with lateral mini-holes were applied to support new urethra in all the cases.</p><p><b>RESULTS</b>The patients were followed up for 1 - 8 years. 208 cases achieved successful results. There were 2 cases of urethral fistula, 6 cases of urethral stenosis at anastomosis site, 4 cases of stenosis at urethral orifice.</p><p><b>CONCLUSIONS</b>The success rate (94.5%) suggests great advantages of the self-made dual tube with lateral mini-holes to support new urethra. It can facilitate drainage and irrigation and reduce the complications such as infection, fistula and stenosis.</p>
