Abstract
This study was carried out in the Department of Urology, National Institute of Kidney
Diseases and Urology, (NIKDU), during the period from Jan' 09 to Dec' 10 to assess the
complications at donor site after lingual mucosal graft harvesting for urethroplasty. A total
of 30 patients with mean age of 36.6 years (rang 21 to 56 years) and mean urethal stricture
length of 36 mm (range 22 to 59 mm) who underwent urethroplasty for anterior urethral
strictures using dorsal onlay of a lingual mucosal graft (LMG) were selected for the study.
The site of the harvest graft was ventrolateral mucosal lining of the tongue. Donor site
complications like pain, numbness, tightness, slurring of speech, salivatory changes and
difficulty in protrusion of tongue were noted. The mean period of follow-up was 14 months
(range 6-18 months). At the first postoperative day, 96% of the patients experienced pain
at donor site and 26% had slurring of speech. Pain was mild to discomforting in 60% and
distressing to excruciating in 37% of the patients. By third postoperative day, 22 (73%)
patients were pain free, 06 (20%) suffered from mild pain and 02 (6%) suffered from
discomforting pain only and none had slurring of speech. On the fifth postoperative day,
only 02 (6%) patient suffered pain. By day 6 of surgery, all patients were pain free. Only
01 (3.3%) patients reported numbness which persisted during the whole period of follow
up. The study showed that LMG is easy to harvest and associated with less postoperative
pain, minor risk of donor site complications and without any functional or esthetic
deficiency. So tongue may be the best alternative donor site for anterior urothroplasty.
