Background: Stricture urethra is a frequent urological problem and substitution urethroplasty is the standard treatment for longer (>2 cm) urerthral strictures, multiple urethral strictures and recurrent strictures. Currently, buccal mucosa graft (BMG) is the preferred donor site for substitution urethroplasty which is associated with donor site morbidities. The mucosa covering the lateral and undersurface of the tongue is identical to the rest of the lining of oral cavity and seems to be associated with less risk of donor site complications. The aim of the study was to compare the surgical outcome and donor site morbidity of buccal versus lingual mucosa graft in anterior urethroplasty. Methods: A prospective experimental study was done in the department of Urology Dhaka Medical College Hospital during the period of April 2017 to September 2018. Total 54 Patients were included by purposive sampling for the study as per inclusion and exclusion Criteria. Patients were than allocated into two groups. Group A consisted of 27 patients where Lingual mucosa graft (LMG) urethroplasty done and group B also consisted of 27 patients where Buccal mucosa graft (BMG) urethroplasty done. Results: In the present study, the baseline characteristics of the patients in group A and Group B were almost similar having no statistically significant difference. The overall surgical outcome between two groups was in group A 92% and in group B 88%. The inter-group difference was not statistically significant. Donor site complications more frequently occurred in Group B. Pain in oral cavity at 3rd week in Group A was in 1(4%) patient and in group B was in 9(36%) patients, at 6th month follow up, eating and drinking problem (Group A 4% versus group B 32%), peri-numbness (Group A 4% versus Group B 28%), oral tightness (Group A 0% versus Group B 32%), salivary disturbance (Group A 0% versus Group B 28%) were significant statistically (p<0.05). Conclusion: We conclude that that lingual mucosa ....
