Abstract：
UNASSIGNED: It is important to predict success before the treatment of urolithiasis. We aimed to predict the success of shock wave lithotripsy (SWL) by comparing twinkling artifact (TA) revealed through colour Doppler ultrasonography (CDUS) with stone density in non-contrast computed tomography (NCCT).
UNASSIGNED: Eighty patients who underwent SWL between January 2021 and January 2022 were included in the study. Patients with stones of 5-20 mm in the renal pelvis and proximal ureter at NCCT were included. Patients\' demographics, Hounsfield units (HU) in NCCT, and TA grades in CDUS were recorded. The stone-free rate after SWL, additional treatments, overall success rates, and the association between TA and success rates were evaluated.
UNASSIGNED: The mean age was 47.41 ±15.08 years. The mean BMI was 24.49 ±3.67 kg/m2. Twenty-three (28.8%) patients were TA grade 0, 33 (41.2%) patients were grade 1, and 24 (30%) were grade 2. The mean HU of TA grades 0, 1, and 2 of stones were 628 ±107, 864 ±123, and 1166 ±292, respectively. The HU increased along with the increase in the TA grade of the stone (p <0.01). The mean number of SWL sessions was 2.26 ±0.75 in patients with TA grade 0, and 2.92 ±0.40 in patients with TA grade 2. The mean number of SWL sessions increased along with the increase in TA grade (p <0.01). The stone-free rate decreased as the TA grade increased. Stone diameter and TA were the only predictors of SWL success.
UNASSIGNED: We think that TA may be useful in predicting SWL success.

摘要：
■在治疗尿石症之前预测成功很重要。我们旨在通过比较彩色多普勒超声（CDUS）显示的闪烁伪影（TA）与非对比计算机断层扫描（NCCT）中的结石密度来预测冲击波碎石（SWL）的成功。
■在2021年1月至2022年1月期间接受SWL的80例患者被纳入研究。包括NCCT时肾盂和输尿管近端结石5-20mm的患者。患者人口统计学，NCCT中的Hounsfield单位(HU)，并记录CDUS中的TA等级。SWL后的无石率，额外的治疗,整体成功率,并评估TA与成功率之间的关联。
■平均年龄为47.41±15.08岁。平均BMI为24.49±3.67kg/m2。23例（28.8%）患者为TA0级，33例（41.2%）患者为1级，24例（30%）为2级。TA等级0、1和2级结石的平均HU分别为628±107、864±123和1166±292。HU随结石TA等级的增加而增加(p<0.01)。TA等级为0的患者的SWL平均次数为2.26±0.75，TA等级为2的患者为2.92±0.40。SWL会话的平均次数随着TA等级的增加而增加(p<0.01)。无石率随着TA等级的增加而降低。结石直径和TA是SWL成功的唯一预测因子。
■我们认为TA可能对预测SWL成功有用。
