Abstract：
OBJECTIVE: To evaluate the usage of shear wave elastography (SWE) in the prediction of the success rate of shock‑wave lithotripsy (SWL) treatment of renal stones.
METHODS: In the present study, SWL was performed for 100 patients presented with renal stones in the duration from May 2022 to August 2023. The patients were divided into 2 groups SWL responders and non-responders. The study compared between the 2 groups in terms of baseline parameters of the patients as age, sex, body mass index (BMI), stone size, stone location, stone density (HU), skin-to-stone distance (SSD), the degree of hydronephrosis and the stone elastography values.
RESULTS: There was no statistically significant relation between stone-free rate and degree of obstruction (p = 0.628), stone size (p = 0.390) upper calyceal location (p = 0.17), middle calyceal location (p = 0.66), and renal pelvis location (p = 1.0). Nevertheless, a statistically significant relation was found as regards lower calyceal location, stone density (HU), and stone Elastography values using multivariate analysis.
CONCLUSIONS: Measurement of stone density by shear wave elastography (SWE) can be used as an alternative to HU in decision-making before SWL. SWL success depends mainly on stone site, HU, and SWE values.

摘要：
目的：评估剪切波弹性成像（SWE）在预测肾结石冲击波碎石（SWL）治疗成功率中的应用。
方法：在本研究中，在2022年5月至2023年8月期间，对100例肾结石患者进行了SWL。将患者分为SWL应答者和非应答者2组。该研究比较了两组患者的基线参数，如年龄，性别,体重指数（BMI），石头尺寸,石头位置,石材密度（HU），皮肤到石头的距离（SSD），肾积水程度和结石弹性成像值。
结果：无结石率与梗阻程度无统计学意义（p=0.628），结石大小（p=0.390）上花柱位置（p=0.17），中柱位置（p=0.66），和肾盂位置（p=1.0）。然而，关于较低的花坛位置，发现了统计学上显著的关系，石材密度（HU），和使用多变量分析的石头弹性成像值。
结论：通过剪切波弹性成像（SWE）测量结石密度可作为SWL前决策中HU的替代方法。SWL的成功主要取决于石材场地，HU,和SWE值。
