The Effect of Staged Transverse Preputial Island Flap Urethroplasty for Proximal Hypospadias with Severe Chordee.
We compare the effects of staged tranverse preputial island flap urethroplasty and the Byars 2-stage procedure in patients with proximal hypospadias and severe chordee.



We studied 87 consecutive children referred for proximal hypospadias with severe chordee between March 2011 and March 2014. Of the cases 42 were repaired with staged tranverse preputial island flap (group 1) and 45 were managed by 2-stage Byars urethroplasty (group 2). Mean ± SD age at first stage surgery was 26.6 ± 13.3 months in group 1 and 24.8 ± 14.7 months in group 2. Postoperative complications in both groups were assessed regarding fistulas, urethral strictures, diverticula, meatal stenosis and glanular dehiscence.



After the second stage 2 patients (4.8%) in group 1 and 10 (23.2%) in group 2 had urethrocutaneous fistulas (p <0.05). One patient (2.4%) in group 1 and 2 patients (4.4%) in group 2 had urethral strictures (p >0.05). All patients with stricture were cured by repeated dilation and no patient required reoperation. One patient (2.4%) in group 1 and no patient in group 2 had diverticulum (p >0.05). No patient in either group had signs or symptoms of meatal stenosis or residual chordee. Three patients (7.1%) in group 1 and 12 (26.7%) in group 2 needed reoperation (p <0.05).



Two-stage urethroplasty, particularly tranverse preputial island flap partial urethroplasty, is appropriate for treating patients with proximal hypospadias and severe chordee. Use of the tranverse preputial island flap can decrease complications associated with the second stage and significantly improve the success rate.
