Buccal mucosa graft urethroplasty for anterior urethral stricture: A single-centre experience

Abstract

Background :To evaluate the outcome and complications after using BMG for anterior urethral stricture.

Procedure: This is a retrospective evaluation of prospectively maintained database. A total of 78 patients were operated from August 2012 to September 2019. Patients were evaluated by using IPSS score, uroflometry, post void residual urine and radiological studies. All patients were operated by using combined regional and general anaesthesia. Buccal mucosa was used in all except three where lingual mucosa was also harvested. The catheter was removed at 3-4 weeks after surgery and patients were followed up at one, three and six months, and then three monthly thereafter.The procedure was considered successful if no intervention was required after surgery.

Conclusion: In 78 patient’s total of 89 procedures have been done over seven years. The procedure was successful in 84.93%, and it failed in 11 patients over a mean follow up of 45 months (7-59 months). In three patients, single DVIU was sufficient whereas in four regular CIC was required after DVIU. In four patients redo surgery was done after six months. Two patients required staged procedure and in three permanent perineal urethrostomy were made due to poor urethral condition, all in older patients. These five patients were excluded from the study. Anastomotic narrowing was most common finding. Redo urethroplasty was successful in all patients.Buccal mucosa as a free graft provides excellent functional outcome in anterior urethral stricture.
