Hypospadias With Severe Chordee: Effect of Urethral Plate Transection on Penile Length

Abstract

ObjectiveTo present our experience with urethral plate (UP) transection to treat hypospadias with severe chordee and examined the effects of this procedure on penile length. The technique involved transecting the UP to correct curvature, facilitating elongation of penile length and reconstruction of the urethra. MethodsWe prospectively studied a cohort of patients with hypospadias with severe chordee who underwent UP transection and urethroplasty at our institution between February 2012 and March 2020. The length of the UP defect (length of penile elongation), complications, and patient and urologist satisfaction with penile length were analyzed. ResultsA total of 510 children were included in our study: 78 cases of distal hypospadias and 432 cases of proximal hypospadias. The mean age at initial surgery was 34.84 ± 20.10 months. The length of the UP defect after transection was 2.51 ± 0.92 cm (1.6-8.0 cm). The length of the UP defect gradually increased with age (P < .05). Seven patients were “poorly satisfied” with their penile length after urethroplasty. The median follow-up duration was 32 months. Of the 510 patients, 108 (21.1%) had complications after urethroplasty, including urethral fistulas in 86 cases, urethral strictures in 9 cases, urethral diverticulum in 8 cases and glans dehiscence in 5 cases. During the follow-up period, 7 patients had mild chordee. ConclusionTransecting the UP for hypospadias with severe chordee can elongate penile length, reduce the recurrence of curvature, and improve patient satisfaction.
