Outpatient catheterless modified Mathieu hypospadias repair.

Distal penile hypospadias was repaired in 59 boys with a modification of the Mathieu technique. Since a watertight urethroplasty is performed without overlying suture lines, catheter drainage and urinary diversion may not be necessary and they were not used in any patient. Penile nerve block and a small dressing allowed for postoperative mobilization. An excellent cosmetic and functional result was achieved with few complications, even in boys who had had prior unsatisfactory repairs. Because the children are ambulatory postoperatively and tolerate voiding through the repair, this procedure often is performed on an outpatient basis.
