Efficacy of laparoscopic urinary tract reconstruction with intraoperative retrograde ureteroscopy-assisted technique for treatment of complex ureteral stricture / 中南大学学报(医学版)

ABSTRACT

To investigate the feasibility and clinical effects of the laparoscopic urinary tract reconstruction with intraoperative retrograde ureteroscopy-assisted technique for the treatment of complex ureteral stricture. 
 Methods: The clinical data of 16 patients with complicated ureteral stricture treated by the laparoscopic urinary tract reconstruction with intraoperative retrograde ureteroscopy-assisted technique from February 2016 to June 2018 were retrospectively analyzed. All 16 patients were iatrogenic stenosis. There were 4 cases of severe hydronephrosis in the affected side, 7 cases of moderate hydronephrosis, and 5 cases of mild hydronephrosis. According to the specific location and length of the ureteral stricture, the corresponding surgical method was selected. 
 Results: All patients successfully completed the operation without conversion to open surgery and organ injury. After the operation, the patients were followed up for 8-18 months. The hydronephrosis of all patients was relieved to varying degrees, and no ureteral restenosis occurred. 
 Conclusion: The laparoscopic urinary tract reconstruction with intraoperative retrograde ureteroscopy-assisted technique can accurately locate the stenosis segment, test the anastomosis effect, expand the inflammatory stenosis, and improve the end-to-end anastomosis of the distal ureteral stricture, which is a new and effective technique for the treatment of complex ureteral strictures.
