PURPOSE: We studied the effect of suturing technique and the impact of urethral plate characteristics on the complication rate following tubularized incised plate urethroplasty.

MATERIALS AND METHODS: We prospectively studied 80 boys (mean age 4.5 years, range 3 to 7) with primary hypospadias in a randomized fashion between January 2004 and May 2005. Of the patients 64 had anterior and 16 had mid penile hypospadias. Patients were allocated into 2 groups according to suture technique, with continuous sutures used in 40 boys and interrupted sutures in 40. We evaluated urethral plate depth, length and width before and after incision. Correlation between suture technique, plate type, width and length, and complication rate was performed.

RESULTS: Mean followup was 3 years. Success rates were 90% and 69% for anterior and mid penile hypospadias, respectively (p = 0.037). Complications developed in 11 patients (13.8%) and consisted of fistula (8), dehiscence (2) and meatal stenosis (3). On univariate analysis the suture technique, depth and length of urethral plate, width after incision and presence of hypoplasia had no impact on complication occurrence. However, urethral plate width before incision was significantly related to complication occurrence (p = 0.048).

CONCLUSIONS: Suture technique has no influence on the outcome of tubularized incised plate urethroplasty. Urethral plate characteristics do not affect the complication rate except for plate width, which significantly affects the outcome. Adequate urethral plate width (8 mm or greater) is essential for successful tubularized incised plate repair.
