■冲击波碎石术(SWL)是治疗输尿管结石的重要工具,特别是当输尿管切除术(URS)不容易获得时。
■该研究的目的是确定与冲击波碎石术(SWL)治疗输尿管下段结石成功相关的因素。
■对2021年1月至2022年2月期间使用SWL治疗的105例输尿管下段结石患者进行回顾性分析。临床和结石参数,包括年龄,性别,和体重指数(BMI),石长,和石材密度进行了分析。使用导电碎石机Sonolithi-sys(EDAPTMS,Vaulx-en-Velin,法国)。我们评估了可能与成功的SWL治疗相关的可用临床和放射学特征。
■67/105例患者(63.8%)治疗成功。多因素logistic回归分析显示,成功的结果与平均结石密度(MSD)(95%CI:1.004-1.009)和患者年龄(95%CI:1.022-1.13)显着相关。性别,BMI,石长不是独立的预测因素。
■结石密度和患者年龄是下输尿管两次SWL后成功预后的独立预测因素。然而,性别,BMI,结石长度不能独立预测治疗成功。
UNASSIGNED: Shockwave lithotripsy (SWL) is an important tool for treating ureteral stones, especially when ureteroscoy (URS) is not readily available.
UNASSIGNED: The aim of the study was to identify factors associated with the success of shockwave lithotripsy (SWL) in the treatment of lower ureteral stones.
UNASSIGNED: Total of 105 consecutive patients with single lower ureteral stones treated with SWL between January 2021 and February 2022 were reviewed retrospectively. Clinical and stone parameters including age, gender, and body mass index (BMI), stone length, and stone density were analyzed. SWL procedures were done using electro-conductive lithotripter Sonolith i-sys (EDAP TMS, Vaulx-en-Velin, France). We evaluated available clinical and radiologic features that might have been related to successful SWL treatment.
UNASSIGNED: Treatment was successful in 67/105 patients (63.8%). Multivariate logistic regression revealed that a successful outcome was significantly related to mean stone density (MSD) (95% CI: 1.004- 1.009) and the patients age (95% CI: 1.022- 1.13). Gender, BMI, and stone length were not an independent predicting factors.
UNASSIGNED: Stone density and patient age were independent predictors of successful outcome after two SWLs in the lower ureter. However, gender, BMI, and stone length did not independently predict treatment success.
