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.
The medical records of prepubertal pediatric patients (age <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.
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.
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.
