Dorsal Versus Ventral Onlay Buccal Mucosal Graft Urethroplasty in Bulbar Urethral Stricture Disease: A Prospective Randomized Study
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2018, Vol 6, Issue 7
Abstract
Our aim was to study efficacy and safety of ventral versus dorsal onlay buccal mucosal graft urethroplasty in patients having long‐segment incomplete bulbar urethral stricture. This was a prospective, randomized study,conducted in a tertiary care hospital. Forty patients with long‐segment (>2 cm) incomplete bulbar urethral stricture were included in the study. They were divided into two study groups of 20 each: group A undergone dorsal onlay buccal mucosal graft urethroplasty and group B undergone ventral onlay buccal mucosal graft urethroplasty. The two groups were studied with regard to International Prostate Symptom Score, maximum flow rate and complications and their success rate were compared. The mean IPSS improved from 24.10 to 4.95 in Group A and from 23.90 to 4.80 in Group B. The mean Qmax improved from 5.57 ml/ min to 18.21 ml/min in Group A and from 5.68 ml/ min to 18.09 ml/ min in Group B. The difference in improvements between the two study arms was not found to be statistically significant. The mean IPSS in both the groups showed sustained improvement at 12 months after surgery. In Group A, the mean IPSS improved from 23.67 to 5.57 and in Group B, the mean IPSS changed from 23.36 to 5.15. In Group A, the mean Qmax improved from 5.71 ml/ min to 17.32 ml/ min at 12 months post-operative and in Group B, the mean Qmax changed from 5.83 ml/ min to 17.31 ml/ min. The difference in improvements between the two study arms was not found to be statistically significant. Dorsal onlaybuccal mucosal graft urethroplasty and ventral onlaybuccal mucosal graft urethroplasty both have good efficacy and low complication rates for treatment of long segment incomplete bulbar urethral strictures. Both the techniques have similar outcomes.
