Abstract

OBJECTIVE: To compare long- term outcomes of buccal mucosa graft (BMG) augmentation urethroplasty for long segment bulbar urethral strictures done by placing the graft ventrally, dorso-laterally and dorsally.

MATERIAL AND METHODS: We conducted a single institution retrospective study on 112 who underwent BMG augmentation urethroplasty for non-traumatic bulbar urethral strictures between January 2005 to December 2014. The cases were divided into three groups based on the site of placement of BMG graft i.e. (a) Ventral (n=44), (b) Dorso-lateral (n=48) and (c) Dorsal (n=20). Follow-up period was from one year to five years. Patients with failed outcomes underwent urethroscopy or retrograde urethrogram to note the site of recurrence of stricture.

RESULTS: Out of 112 cases 91 (81%) were successful and 21 (19%) failed. The success rates for ventral, dorso-lateral and dorsal BMG augmentation procedures were 89%, 79% and 70%, respectively (p=0.18). Among 21 failed cases, 12 cases (57%) had stricture at proximal anastomotic site, 4 cases (19%) at graft and 5 cases (24%) at distal anastomotic site (p=0.01).

CONCLUSION: The overall success rate for BMG augmentation urethroplasty is equal for all techniques. Ventral onlay urethroplasty provides better exposure of proximal anastomotic site thus it is associated with minimum proximal anastomotic site recurrence rates. Patients with extensive spongiofibrosis and long segment strictures had higher rates of failure.
