Microsurgical hypospadias repair.

Successful primary hypospadias repair depends on careful execution of surgical principles, particularly during the urethroplasty portion of the procedure. These principles include careful tissue handling, development of well-vascularized flaps, and avoidance of placing sutures in the uroepithelial surface. Despite meticulous repair, the complication rate requiring secondary surgery is 15 to 30 percent. For the past year, the authors have utilized an operating room microscope, microsurgical instruments, a specially designed microsuture, and a Biooclusive dressing to decrease the postoperative morbidity and subsequent complications requiring secondary surgery (6.5 percent). A comparison of 50 hypospadias patients on whom no microsurgical repair had been used was made with 62 patients on whom microsurgical techniques were employed. The nonmicrosurgical group had 17 complications, 12 of which required reoperation (24 percent). The microsurgical group had 8 complications, 4 of which required reoperation (6.5 percent).
