Abstract：
OBJECTIVE: We sought to prospectively evaluate the impact of previously failed SWL on subsequent URS outcomes in the treatment of upper urinary tract stones.
METHODS: Between May 2021 and May 2023, one hundred thirty-six patients with proximal ureteral stones < 1.5 cm and renal stones < 2.5 cm who were candidates for URS were prospectively assigned to a non-SWL group, which included patients without a history of failed SWL before URS, and a post-SWL group, which included patients with a history of failed SWL before URS. The success rate was the primary outcome. The perioperative data of the two groups were compared.
RESULTS: The stone-free rate was 83.3% in the post-SWL group versus 81.3% in the non-SWL group, and 8.3% in the post-SWL group versus 9.4% in the non-SWL group had clinically insignificant residual fragments. There was no significant difference in the stone-free rate or success rate between the groups. No significant differences in intraoperative fluoroscopy time, operative time, intraoperative stone appearance, perioperative complications, or the presence of embedded fragments in the ureteral mucosa were detected between the two groups.
CONCLUSIONS: Compared with patients who underwent primary URS, patients who underwent salvage URS for upper urinary tract stones had similar stone-free rates, success rates, operative times, fluoroscopy times, and complication rates without any significant differences.

摘要：
目的：我们试图前瞻性地评估先前失败的SWL对上尿路结石治疗后的URS结局的影响。
方法：在2021年5月至2023年5月之间，有136例输尿管近端结石<1.5cm和肾结石<2.5cm的患者被前瞻性地分配到非SWL组，其中包括在URS之前没有SWL失败史的患者，和一个后SWL组，其中包括在URS之前有SWL失败史的患者.成功率是主要结果。比较两组患者的围手术期资料。
结果：术后SWL组无结石率为83.3%，非SWL组为81.3%，术后SWL组8.3%和非SWL组9.4%有临床上不显著的残留片段。两组间结石清除率或成功率无显著差异。术中透视时间无显著差异,手术时间,术中结石外观，围手术期并发症,或在两个组之间检测到输尿管粘膜中存在嵌入的碎片。
结论：与接受原发性URS的患者相比，接受上尿路结石抢救URS的患者无结石率相似，成功率,手术时间，透视次数,并发症发生率无明显差异。
