RESUMEN
<p><b>OBJECTIVE</b>To summarize the experience in one-stage urethroplasty with pedicled scrotal skin flap for hypospadias, and improve its therapeutic effect.</p><p><b>METHODS</b>We retrospectively analyzed the clinical data of 310 cases of hypospadias (except coronal hypospadias) treated by one-stage urethroplasty with pedicled scrotal skin flap. All the patients were followed up for 6 to 24 months.</p><p><b>RESULTS</b>No postoperative complications were observed except urinary fistula, which occurred in 12.6% of the patients. Postoperative fistula formation was associated with the type of hypospadias, the length of the urethral defect and postoperative comprehensive medication, but not with the stent indwelling time after surgery. Most of the fistulae were located at the base of the penis.</p><p><b>CONCLUSION</b>One-stage urethroplasty with pedicled scrotal skin flap is a simple and effective option for all types of hypospadias except the coronal type, and postoperative treatment is very important.</p>
