One-Stage Urethroplasty for Strictures in Maiduguri, North Eastern Nigeria

Background. Urethral stricture is a frequent cause of lower urinary tract obstruction worldwide. The aim of this study is to present our experience with one-stage urethroplasty. Methods. All males that underwent one-stage urethroplasty between January 2001 and December 2010 were retrospectively reviewed. Details of their biodata, clinical presentation, diagnostic investigations, operative treatment, postoperative complications, and other outcome of surgery were extracted and analyzed. Results. Ninety-one patients aged 8–76 years, (mean; 45.6 ± 19.7) with urethral stricture were studied. Postinfective strictures accounted for 58.2% and postprostatectomy strictures for 3.3%. Twenty-six (27.9%) of the strictures were in the posterior urethra of which 18 (59.2%) were posttraumatic. Fifty-seven strictures (61.3%) were in the anterior urethra of which 51 (54.8%) were postinfective. Thirty-nine (42.9%) patients had end to end anastomosis, 29 (31.9%) flap augmentation and 17 (18.7%) tabularized flap substitution, and 6 (6.6%) dorsal onlay grafts (5 with buccal mucosa and 1 with penile skin). There were 18 (19.8%) cases of wound infection, 12 (13.2%) of restricture and 6 (6.6%) cases of urethrocutaneous fistula. Satisfactory urinary stream was found in 77 (84.6%) patients. There was no mortality. Conclusion. Infection is the commonest cause of urethral stricture followed by trauma, and one-stage urethroplasty give excellent results.
