Kidney stone disease (KSD) is a prevalent and significant global urological issue, and ureteroscopic holmium laser lithotripsy (UHLL) is a primary treatment option. This study aimed to assess the impact of stone computed tomography (CT) value on the outcomes of UHLL in treating KSD.
A retrospective analysis was conducted on the clinical data of 101 patients who underwent UHLL at our hospital between September 2022 and December 2023. Patients were categorised into two groups based on stone CT values. Demographic characteristics, intraoperative factors, stone clearance, and complications were evaluated and compared between the low- and high-CT groups.
The high-CT group had significantly longer intraoperative durations than the low-CT group ( < 0.001). Fragmentation time was considerably higher in the high-CT group ( < 0.001). Stone clearance rates after three postoperative months were substantially higher in the low-CT group (98.04%) than in the high-CT group (84.00%) (χ = 4.523, = 0.033). Although the low-CT group had a lower complication rate, the difference was insignificant ( = 0.356). CT values showed a positive correlation with durations of operation and fragmentation ( < 0.01), and a negative correlation with stone clearance ( < 0.05).
Stone CT values are key factors influencing the procedural outcomes and postoperative complications of UHLL.
肾结石病（KSD）是一种普遍且严重的全球泌尿科问题，输尿管镜钬激光碎石术（UHLL）是主要的治疗选择。本研究旨在评估结石 CT 值对 UHLL 治疗 KSD 结局的影响。
对 2022 年 9 月至 2023 年 12 月在我院接受 UHLL 的 101 例患者的临床资料进行回顾性分析。根据结石 CT 值将患者分为两组。评估并比较低 CT 值组和高 CT 值组之间的人口统计学特征、术中因素、结石清除率和并发症。
高 CT 值组的术中时间明显长于低 CT 值组（<0.001）。高 CT 值组的碎石时间明显较高（<0.001）。低 CT 值组术后 3 个月的结石清除率（98.04%）明显高于高 CT 值组（84.00%）（χ=4.523，=0.033）。尽管低 CT 值组的并发症发生率较低，但差异无统计学意义（=0.356）。CT 值与手术时间和碎石时间呈正相关（<0.01），与结石清除率呈负相关（<0.05）。
结石 CT 值是影响 UHLL 手术结果和术后并发症的关键因素。
