Purpose: Various techniques have been described to correct distal hypospadias but many are best suited to patients with subtle specific nuances of meatal and/or glanular configuration. We describe a simplified approach to these defects using the modified Thiersch-Duplay technique with or without hinging the urethral plate (the Snodgrass maneuver). Materials and Methods: Between 1990 and 1997 we performed the modified Thiersch-Duplay repair as the primary procedure for repairing hypospadias in 197 boys. We initially performed urethral plate hinging (the Snodgrass maneuver) in 1994. By 1997, 82% of our patients were undergoing repair using the hinge technique. Urethroplasty coverage was provided by a second layer of adjacent local tissue or by a pedicle of subcutaneous tissue. Results: Reoperation was required in 5 boys (2.5%) with fistula and 1 (0.50%) with urinary extravasation. A fistula developed in 4 of the 63 cases (6.4%) in which adjacent local tissue was used to cover the urethroplasty and in 1 of 130 (0.80%) in which a pedicle of subcutaneous tissue was used. Overall 97% of the boys had an excellent result requiring no secondary operative procedure. Conclusions: The modified Thiersch-Duplay technique with or without urethral plate hinging is reliable for correcting distal hypospadias. The risk of fistula is almost eliminated when a vascularized pedicle of subcutaneous tissue is used to cover the repair. This technique has virtually supplanted all other methods that we used in the past to correct distal hypospadias.
