Long anterior urethral stricture due to variable etiological factors constitutes a challenge for reconstruction. We evaluated our centers experience with cases of long anterior urethral stricture due to different etiologies that were managed by 2-stage substitution urethroplasty using buccal mucosal graft procedure.
During the period between November 2009 and November 2016. All cases with long anterior urethral stricture that were planned for substitution urethroplasty in our department were enrolled in this study. The first stage was excision of most fibrotic areas of the urethral plate, the remaining of the urethra is laid open and augmented with buccal mucosal graft for second stage closure after 6-9 months.
The study included 123 patients who underwent first stage, 105 patients of them underwent second stage urethroplasty. Eighteen cases were missed after first stage. The mean (range) age was 38.4 (17-60 years). The mean (range) stricture length was 8.3 (4-13 cm). The cause of stricture was idiopathic in 47, inflammatory in 15, lichen sclerosus in 26 and post failed hypospadias repair in 35 patients. First stage was complicated by graft contracture in 11 (8.9%) patients that needed re-grafting, 5(4.1%) patient had bleeding from the buccal mucosa site that needed haemostatic sutures, oral numbness was reported in 7 (5.7%) patients. Second stage was complicated by wound dehiscence in 2(1.9%) patients, restricture in 11 (10.5%), fistula in 6 (5.7%) patients, meatal stenosis in 3 (2.9%). The overall success rate was 79.1% (83 cases out of 105) with a mean (range) follow-up of 34.7 (10-58 months).
Staged urethroplasty using buccal mucosal graft procedure is an effective surgical option for patients with long anterior urethral strictures especially for patients with lichen sclerosus and those with failed previous surgical repair.
