Objectives: We evaluated the efficacy of one-stage dorsal inlay buccal mucosal graft (BMG) urethroplasty in the management of ex-tensive anterior urethral strictures.
Materials and Methods: Between Decem-ber 2010 and December 2011, 18 patients with anterior urethral strictures underwent ureth-roplasty in our clinic. Six of 18 patients who received one-stage buccal mucosal greft ureth-roplasty due to extensive anterior urethral stric-ture were included in this study. Patients were evaluated with preoperative retrograd uret-rography (RU), voiding cystourethrography (VCUG), and urethrocystoscopy. All patients received RU+VCUG, uroflowmetry and post-void residual urine determination at postopera-tive 3rd week and 3rd month, then followed ye-arly thereafter. Cure was defined as no evidence of obstruction on uroflowmetry, the absence of any strictures that may require additional in-tervention and subjective patient satisfaction at the last visit.
Results: Mean patient age was 43.5 years. The mean length of BMG was 13 cm (12-16), mean operation time was 170 (130-240) min, and estimated blood loss was 60 (30-110) ml. Mean hospitalization was 3.7 days. There were no intraoperative or postoperative compli-cations. With at least one year of follow-up (range=12-26 months), objective and subjec-tive success was achieved in all patients. Mean Qmax was significantly improved at the last follow-up as compared to preoperative me-asurements (24.5±8.3 ml/s vs. 6.2±5.8 ml/s, p=0.001).
Conclusion: One-stage dorsal inlay BMG urethroplasty seems as a feasible option in se-lected cases who have extensive stenosis of the anterior urethra.
