Abstract:
Objective To analyze the donor site complications of male patients with long segment anterior urethral strictures that underwent urethroplasty by using a long-strip lingual mucosal grafts (LMG) six months later.Methods Between August 2006 and December 2014,a total of 81 patients with long segment anterior urethral stricture underwent a procedure of urethroplasty using a long-strip LMG.The mean patients' age was 41.2 years (range 18-74) and the mean urethral stricture length was 12.1 cm (range,8-20 cm),a single LMG was more than 9 cm.Two techniques of urethroplasty were performed:One-sided dorsal graft augmentation urethroplasty was performed in 70 patients,12 of the 70 patients underwent urethroplasty by using a LMG in addition to a BMG,owing to the presence of very long strictures;Dorsal patch graft urethroplasty was performed in 11 patients.Results Of the 81 patients a single long-strip LMG with length of 9-11 cm was used in 52 patients,LMG measured ≥12 cm in 17,and LMG combined with buccal mucosal graft (BMG) in 12.The mean follow-up period was 41 months (range,15-86 months) postoperatively.The overall urethroplasty success rate was 82.7％.Six months after the operation,28 patients (34.6％) reported a minimal to moderate difficulty in fine motor movement of the tongue (difficulty with spitting tiny fish bones).Among these 28,22 patients (27.2 ％) had associated numbness over the donor site,10 patients (12.3％) had parageusia,and 11 patients (13.6％) reported slurring of speech.The donor site complications occurred higher in patients with LMG length ≥ 12 cm (14/29) than those patients with LMG length ＜ 12 cm (14/52)(x2 =19.049,P ＜0.01).At 12 months,5 patients (6.2％)reported minimal difficulty in fine motor movement of the tongue,and reduced to 1 patient at 24 months.Conclusions The donor side complications after long-strip lingual mucosal graft for the treatment of longsegment anterior urethral strictures are primarily limited to the first postoperative year,the incidence of complications appeared to be related to the length of the harvested graft.
