Safety and Efficacy of Trans-Perineal Urethroplasty for Management of Post-Traumatic Urethral Strictures in Pediatric Age-Group

Abstract

<b><i>Introduction:</i></b> Trans-perineal urethroplasty is the preferred treatment for distraction urethral injuries in adults. However, management of such injuries in children is challenging because of functional implications in a growing child. In the present study, we aim to evaluate the safety and efficacy of perineal urethroplasty for distraction urethral injuries in children. <b><i>Methods:</i></b> The medical records of prepubertal pediatric patients (age &#x3c;14 years) with traumatic urethral distraction injuries managed by perineal urethroplasty were retrospectively reviewed and analyzed with respect to demographics, stricture characteristics, management, complications, follow-up, and outcome. <b><i>Results:</i></b> A total of 14 patients were included in the study. Ten had membranous, and 4 had bulbar urethral strictures. All membranous strictures were secondary to pelvic trauma; bulbar strictures were secondary to blunt perineal trauma; 7 patients had associated pelvic fractures. Anastomotic urethroplasty was used in 10 patients (71.4%) and buccal mucosal graft urethroplasty was done in 4 patients (38.6%). The mean follow-up duration was 56 months (range 24–76). Surgery was primarily successful in 85.7%. Failed repair in 2 patients was successfully managed with augmented anastomotic urethroplasty. Post-operatively, the mean maximal urinary flow rate was 26.4 mL/s. No significant complications occurred. All boys are continent. There was no chordee or urethral diverticula, during follow-up. <b><i>Conclusion:</i></b> In pediatric patients, bulbar and membranous strictures can be treated successfully with urethroplasty using the perineal approach. Longer follow-up is needed to confirm that these good results are maintained as these patients cross into adulthood, especially as these repairs were done before puberty.
