Etiology and outcome of the perineal repair of posterior and bulbar urethral strictures in children: a single surgeon experience.

OBJECTIVE

To evaluate the etiology of posterior and/or bulbar strictures in children in an industrialized country and assess the outcome of its repair by perineal approach. Urethral strictures in children are rare and often challenging to treat. Trauma is the main etiology in developing countries. However, data for industrialized countries are sparse.

MATERIAL AND

METHODS

Retrospective analysis of 17 patients treated with perineal urethroplasty 2001-2010. Data were assessed by chart review and non-validated standardized questionnaire. Hypospadias cases were excluded. Reconstruction was performed by stricture excision and primary anastomosis, or a single-staged or two-staged buccal mucosa graft.

RESULTS

Mean age at surgery was 7.9 years (range 1-13) and mean follow-up was 42.6 months (4-115). Eight patients (47.1%) had post-traumatic strictures, five (29.4%) had a history of posterior valves, and previous transurethral catheterization and irradiation each accounted for one patient (5.9%). In the remaining two (11.8%), the etiology was unknown. The success rate was 88.9%. All but one patient were continent postoperatively.

CONCLUSIONS

Most common etiology for open urethral reconstruction in children was trauma and previous valve treatment. In our hands the perineal approach for stricture repair is safe and successful. Stricture recurrence rate is low, and incontinence is only associated with additional bladder neck trauma.
