Outcome and donor site morbidity of buccal versus lingual mucosal graft in substitution urethroplasty for anterior urethral stricture
Keywords:Substitution urethroplasty, Lingual mucosa, Buccal mucosa
Background:To compare buccal versus lingual mucosal grafts in substitution urethroplasty in terms of surgical outcome and donor site morbidity.
Methods: A total of 50 patients who underwent single stage substitution urethroplasty for anterior urethral stricture from March 2008 to December 2014 were included in the study. Out of these 27 had buccal mucosal graft urethroplasty and 23 had lingual mucosal graft urethroplasty. The patients were compared for surgical outcome and donor site morbidity.
Results:The mean age and stricture length were comparable in the two groups. The surgical outcome was also comparable in the two groups with 3 failures in buccal mucosal group and 2 in lingual mucosal group.
Lingual mucosal graft was easier to harvest but overall donor site complications were comparable in both the groups.
Conclusions:Lingual mucosal graft harvesting is easier and the surgical outcome is comparable to buccal mucosal grafts. The donor site morbidity is comparable to buccal mucosal grafts. Lingual mucosal grafts is especially useful in patients with sub mucosal fibrosis and unhealthy buccal mucosal.
