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.
■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。
