ABSTRACT  

Objective: To assess the outcome of single stage dorsolateral onlay buccal mucosal urethroplasty for long anterior urethral strictures (>4cm long) using a perineal incision.
Materials and Methods: From August 2010 to August 2013, 20 patients underwent BMG urethroplasty. The cause of stricture was Lichen sclerosis in 12 cases (60%), Instrumentation in 5 cases (25%), and unknown in 3 cases (15%). Strictures were ap¬proached through a perineal skin incision and penis was invaginated into it to access the entire urethra. All the grafts were placed dorsolaterally, preserving the bulbospon¬giosus muscle, central tendon of perineum and one-sided attachement of corpus spon¬giosum. Procedure was considered to be failure if the patient required instrumentation postoperatively.
Results: Mean stricture length was 8.5cm (range 4 to 12cm). Mean follow-up was 22.7 months (range 12 to 36 months). Overall success rate was 85%. There were 3 failures (meatal stenosis in 1, proximal stricture in 1 and whole length recurrent stricture in 1). Other complications included wound infection, urethrocutaneous fistula, brownish discharge per urethra and scrotal oedema.
Conclusion: Dorsolateral buccal mucosal urethroplasty for long anterior urethral stric¬tures using a single perineal incision is simple, safe and easily reproducible by urolo¬gists with a good outcome.
