ObjectiveTo describe a new technique for harvesting the long lingual mucosal graft (LMG) to repair the long-segment urethral strictures.MethodsWe performed a retrospective observational study of patients from whom LMGs were harvested from the lateral lining of the tongue for the long-segment anterior urethral strictures repair from 2012 to 2014 at the Shanghai Sixth People's Hospital. Patients who had 12 months minimum follow-up were included. Patients with incomplete clinical records were excluded. The LMG was applied on the urethra according to the dorsal onlay technique.ResultsThe primary outcome of the study was the postoperative failure-free survival rate. The secondary outcome was the rate of early and late complications at the harvesting site. Success was defined as Qmaxâ>12âml/s and no postoperative procedures. One hundred and one patients were included. Median stricture length was 7.1â±â3.6âcm; median LMG length was 7.2â±â3.6âcm. The success rate was 81.2% with a median follow-up of 23 months. Complications at the donor site had occurred in 41 patients at 6-months follow-up, and persisted in 18 patients at the 12-months follow-up. A bilateral harvest and harvest length were the main factors influencing complication rate (Pâ=â.0038 for 6 months and Pâ=â.1112 for 12 months). Almost half of donor site complications subsided within 12 months (Pâ=â.0018).ConclusionIn patients requiring long oral graftsâ>7âcm to repair anterior strictures, a valid option is to harvest the graft from the lateral lining of the tongue.
