Substitution urethroplasty for anterior urethral strictures: buccal versus lingual mucosal graft.
OBJECTIVE
To compare the results of substitution urethroplasty and donor site morbidity between buccal mucosal graft (BMG) and lingual mucosal graft (LMG).


METHODS
Patients who underwent single-stage dorsal onlay free oral mucosal graft substitution urethroplasty by Barbagli's technique between January 2004 and August 2008 were included in this study. Patients who underwent buccal (cheek, lip) mucosal graft urethroplasty were included in group I and those who underwent LMG urethroplasty (tongue) were included in group II. All patients underwent complete evaluation of the stricture including inspection of the oral cavity. Exclusion criteria were stricture length <3 cm and complex strictures which required a multistage procedure.


RESULTS
The results of urethroplasty were similar in both groups in terms of blood loss, duration of postoperative hospitalization, complications encountered at urethroplasty site, mean postoperative Q(max) and mean postoperative AUA symptom score. Early slurring of speech complications was seen in group II, but not in group I. The long-term complications of persistent oral discomfort, perioral numbness and tightness of the mouth were seen only in group I.


CONCLUSIONS
LMG urethroplasty is a good substitute for BMG urethroplasty with equally good results of urethroplasty with lower donor site morbidity.
