Abstract：Objective： To investigate the efficacy and safety of laparoscopy in treating complicated posterior urethral stricture. Methods： The clinical data of 26 patients with complex posterior urethral stricture from September 2014 to September 2017 were analyzed retrospectively. Results： All the 26 patients completed the operation successfully. The operation time was (160±55) min (130-230 min). The hospitalization was (7.6±1.4) d （3-11 d） after operation. The urethral catheter was removed 2 weeks after the operation. All patients were followed-up for 18 months(7-36 months) after the operation, and no case was lost. After extubation, the urination was unobstructed in 24 cases. The maximum urine flow rate was (19.0±4.6) mL/s. Urinary retention occurred in 1 case after removal of urethral catheter. After 4 weeks, the catheter was removed again and urethral dilatation was regularly performed for 6 weeks. The voiding patency rate and maximum urine flow rate were 15.6 mL/s after 6 months. One case had membranous urethral stricture 3 months after extubation. After cold-knife internal urethrotomy the urination was unobstructed. Conclusion： laparoscopy can be used of minimally invasive treatment of posterior urethral stricture safely and reliably. Combined with open surgery for posterior urethral stricture, the operation can achieve less trauma and restenosis. It is an effective measure in treating posterior urethral stricture, and could be widely used in clinical.
