[Analysis of success rates of uretroplasty for adult male bulbar urethral stricture: A systematic review].

UNLABELLED: Male urethral stricture disease is prevalent and has an important impact on quality of life. Direct visual urethrotomy and dilatations have high rates of recurrence.

OBJECTIVES

The aim of this review of literature was to evaluate the success rates of different techniques of urethroplasty for strictures of the bulbar urethra.

METHODS

We performed a systematic review of the MEDLINE literature from 2004 to 2015 following the PRISMA's statement recommendations. Key words were: urethroplasty, urethral reconstruction, onlay, graft, urethral stricture. Inclusion criteria were original articles describing the results of urethroplasty for bulbar urethral stricture in an adult male population. A minimum follow-up of 24 months was required.

RESULTS

From 891 articles of the literature, 20 are studied in this review. Only 3 studies were prospective. The success rate of anastomotic urethroplasty varied from 68.7 to 98.8% for strictures from 1 to 3.5cm, from 60 to 96.9% for augmented urethroplasty performed for strictures from 4.2 to 4.7cm. Substitution urethroplasty with grafts presented from 75 to 89.8% of success for strictures from 2.6 and 4.36cm. Overall, 19/20 studies used buccal mucosal graft.

CONCLUSION

The success rate of urethroplasty for bulbar urethral stricture is high; the surgical technique should be adapted to the length of the stricture.
