Time to complication after primary pediatric hypospadias repair with transverse preputial island flap urethroplasty.

More than 90% of complications after the transverse preputial island urethroplasty of hypospadias occurred within 1 year, with those related to proximal hypospadias presenting earlier than those of midshaft/distal hypospadias. Surgeons may consider a more frequent follow-up within the first year after surgery to detect these complications as early as possible.
