This paper reviews a short series of patients with distal hypospadias who were treated by Mustardc's one-stage technique, to which we have added a minor modification by tubing the flap before penis tunnelization. A single-stage repair has obvious advantages over a more conventional multistage procedure. The advantage of tubing the flap is early healing, and it reduces the risk of fistula formation, even in the presence of infection, which is very common in this country. The new urethral opening is situated at the fossa navicularis, and the functional results are excellent.
