Abstract: Objective  To observe the effect and complications of non-dissected cavernous body of urethra combined with widening of urethral lumen with lingual mucosa in the repair and reconstruction of bulbar urethral stricturein males. 
Methods  A total of 21 male patients with bulbar urethral stricture were enrolled in this study. After the urethra of the bulbar stenosis was isolated, the corpus cavernosum was not cut off and the urethral lumen was opened longitudinally. Among them, 12 cases of urethral stricture were less than 2 cm in length, and a spoon-shaped urethral anastomosis was performed directly. Nine cases of urethral stricture were more than 2 cm in length. Considering the tension of direct urethral anastomosis, lingual mucosa served as a repair material, and the urethra was capped to widen the urethral lumen. The curative effect of all cases and the incidence of related complications such as urinary fistula, urethral stricture and erectile dysfunction were observed. 
Results  All patients underwent surgery successfully. Of them, 18 cases(85.71%) were successful in one operation without any complications. One case had severe infection after lingual mucosa urethroplasty, which resulted in urethral fistula after anti-inflammatory treatment, multiple dressing changes and rinses. Six months later, the urethral fistula was repaired, the healing was good and he urinated smoothly. One case developed a local hematoma of the scrotum. After debridement, compression bandaging and dressing change, he recovered well. One case had a dehiscence of the perineal incision. After dressing changes, anti-inflammatory and infrared treatments, the incision healed well. After the catheter was removed, the urethra became narrow. After the urethra was dilated, urination could be unblocked. No erectile dysfunction occurred in 21 patients. All patients were followed up, and the patients should be able to urinate smoothly, and the urethra dilatation could persist for more than 3 months. 
Conclusion  The clinical application of non-dissected cavernous body of urethra combined with widening of urethral lumen with lingual mucosa in the repair and reconstruction of bulbar urethral stricture has a positive effect and will not increase the incidence of postoperative erectile dysfunction. Therefore, it is worthy of clinical promotion.
