[Efficacy analysis of laparoscopy combined with flexible ureteroscope in the treatment of complex ureteral stricture].

The dual-endoscopic technique enhances intraoperative precision in complex ureteral stricture management by integrating real-time luminal visualization with extraluminal anatomical guidance. This approach minimizes excessive resection of healthy ureter, optimizes reconstruction strategies, and reduces postoperative recurrence. The modified positioning protocol further improves ergonomic efficiency, making it a reliable and adaptable option for challenging ureteral pathologies.
