Six hundred sixteen procedures for management of ureteral calculi were reviewed. Five hundred six (82%) were endoscopic procedures; 207 were looped catheter manipulations and 299 were stone basket extractions. The retrieval efficiency for ureterolithotomy, looped catheter manipulation, and basket extraction was 100, 46, and 71 per cent, respectively. The average size of calculus was 7.9 mm (lithotomy), 6.9 mm (looped catheter), and 4.2 mm (basket). Looped catheters were used for larger stones, for stones higher in the ureter, and for stones that could not be extracted with a basket. The looped catheter can be utilized for stones at any level of the ureter. There was no significant difference in the complications from use of the looped catheter or stone basket, except for a longer hospital stay for patients who had manipulation with looped catheters than with stone baskets.
回顾了616例输尿管结石的治疗手术。其中506例（82%）为内镜手术；207例为环形导管操作，299例为结石篮取出术。输尿管切开取石术、环形导管操作和结石篮取出术的取石成功率分别为100%、46%和71%。结石的平均大小为7.9毫米（切开取石术）、6.9毫米（环形导管）和4.2毫米（结石篮）。环形导管用于较大的结石、输尿管较高部位的结石以及无法用结石篮取出的结石。环形导管可用于输尿管任何部位的结石。使用环形导管或结石篮的并发症无显著差异，只是接受环形导管操作的患者住院时间比接受结石篮操作的患者更长。
