Objectives: to evaluate Dorsal versus ventral onlay buccal mucosal graft urethroplasty for long segment anterior urethral stricture. Methods: This was a prospective, randomized study. Patients with long segment (>2 cm) anterior urethral stricture and meeting eligibility criteria were Included in our study. They were randomized into two study groups: group A undergoing dorsal onlay buccal mucosal graft urethroplasty and group B undergoing ventral onlay buccal mucosal graft urethroplasty. The two groups were compared statistically with regard to International Prostate Symptom Score, maximum flow rate, intraoperative parameters and complications. Results: A total number of 40 patients were randomized into two equal groups of 20 patients each. The preoperative International Prostate Symptom Score, maximum flow rate and intraoperative parameters were not significantly different between the two groups. At 6-month follow up, the mean International Prostate Symptom Score was3.65 ± 1.35 and 4.25 ± 2.02, whereas the mean maximum flow rate was 18.95 ± 1.76 and 19.65 ± 1.82 in group A and B, respectively. There were no significant differences between both groups in terms of International Prostate Symptom Score and maximum flow rate data at 3- and 6-month follow up. The success rate of surgery was similar in both groups (95 %). Conclusion: We concluded that in long segment anterior urethral stricture both dorsal onlay BMGU and ventral onlay BMGU have comparable efficacy and complication rate, technique selection should be surgeon preference.
