Does the type of urinary diversion affect the result of distal hypospadias repair? A prospective randomized trial.

Purpose: The purpose of this review is to evaluate different techniques in urinary diversion and urethral stenting in hypospadias surgery.

Patients And Methods: The surgical procedure included 192 tubularized incised plate (TIP) repairs for distal penile hypospadias. The patients were prospectively randomized into three groups: In group A, a urethral catheter was used as a stent and for diversion of urine (63 patients); in group B we use no urethral stenting (63 patients), only a suprapubic catheter; and in group C we use a suprapubic diversion and we put a small catheter in the anterior urethra only (66 patients).
