To compare the efficacy of flexible ureteroscopy for single urinary stones with that of multiple urinary stones.
A retrospective study was conducted on patients who underwent flexible ureteroscopy in Qilu Hospital of Shandong University from January 2016 to March 2021. Propensity score matching was used to match patients with no statistical difference in preoperative clinical data, and they were divided into solitary calculi and multiple calculi two groups. The postoperative hospital days, operation time, complications and stone free rate were compared between the two groups. And multiple stones were divided into high group (S-ReSc > 4) and non-high group (S-ReSc ≤ 4) for analysis.
313 patients were counted. After propensity score matching, 198 patients were finally included in the study. There were 99 cases in the solitary stone group and the multiple stone group. There were no significant differences in postoperative hospital days, complications and stone free rate between the two groups. The operation time of patients with solitary stone group was significantly shorter than that of patients with multiple stones (65.00 min, 45.00 min VS 90.00 min, 50.00 min, < 0.001). The SFR of high group in the multiple stones group was significantly lower than that in the non-high group (7, 58.3% VS 78, 89.7%, = 0.013).
Despite the longer operation time, flexible ureteroscopy has similar outcomes in the treatment of multiple (S-Rec ≤ 4) compared to solitary calculi. Although, this doesn't apply when S-ReSc > 4.
比较输尿管软镜治疗单发与多发尿路结石的疗效。
回顾性研究2016年1月至2021年3月在山东大学齐鲁医院接受输尿管软镜手术的患者。采用倾向评分匹配法，使术前临床资料无统计学差异的患者进行匹配，并分为单发结石组和多发结石组。比较两组术后住院天数、手术时间、并发症及结石清除率。将多发结石分为高分组（S-ReSc＞４）和非高分组（S-ReSc≤４）进行分析。
共纳入313例患者。经倾向评分匹配后，最终纳入研究198例，单发结石组和多发结石组各99例。两组术后住院天数、并发症及结石清除率比较，差异无统计学意义。单发结石组患者手术时间明显短于多发结石组（65.00分钟，45.00分钟对90.00分钟，50.00分钟，P＜0.001）。多发结石组高分组结石清除率明显低于非高分组（7例，58.3%对78例，89.7%，P=0.013）。
尽管手术时间较长，但输尿管软镜治疗多发结石（S-Rec≤4）与单发结石的疗效相似。然而，当S-ReSc＞4时不适用。
