[Efficacy of laparoscopic urinary tract reconstruction with intraoperative retrograde ureteroscopy-assisted technique for treatment of complex ureteral stricture].

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.
