研究了剪切波弹性成像技术在诊断肾脏梗阻性疾病方面的应用价值。首先选择80例肾脏梗阻性疾病（输尿管结石梗阻49例、先天性输尿管狭窄18例、膀胱癌侵犯输尿管末端5例、输尿管息肉3例以及盆腔肿瘤压迫5例）作为观察组，同时选取80例健康体检者作为对照组，利用常规二维超声分别测量其肾脏长径和皮质厚度，再利用剪切波弹性成像技术测量观察组患者中梗阻侧肾脏皮质的弹性模量和对照组患者的肾脏皮质部弹性模量，并将两者数据进行对比分析。结果表明，观察组中梗阻侧肾脏体积大于正常对照组的，其皮质厚度较正常对照组的薄，梗阻侧肾皮质的平均弹性模量明显高于对照组中正常肾脏皮质的平均弹性模量，对两组数据比较后发现有显著性差异，而且梗阻程度越重，病程越长，弹性模量就越高。因此，剪切波弹性成像技术能够定量评估肾脏皮质的损害程度，该项研究有利于对患者病情进行判断及制定治疗方案。

The application value of shear wave elastography in the diagnosis of renal obstructive diseases was studied. First, 80 cases of renal obstructive disease (49 cases of ureteral obstruction, 18 cases of congenital ureteral stricture, 5 cases of bladder cancer invading the ureteral end, 3 cases of ureteral polyps and 5 cases of pelvic tumor compression) were selected as the observation group, and 80 cases of health were selected. The physical examination was used as a control group to measure the size and cortical thickness of the kidney by conventional two-dimensional ultrasound. The shear wave elastography was used to measure the elasticity modulus of the obstructed renal cortex in the observation group and the renal cortex of the control group. The elasticity modulus value, and the two data are compared and analyzed. The results showed that the obstructed kidney volume in the observation group was larger than that in the normal control group, and the cortical thickness was thinner than that in the normal control group. The average elasticity modulus of the obstructed renal cortex was significantly higher than the average elasticity modulus of the normal renal cortex in the control group. Value, there is a significant difference between the two groups of data, and the more severe the obstruction, the longer the course of disease, the higher the elasticity modulus value. Therefore, shear wave elastography can quantitatively assess the degree of damage in the renal cortex. This study is conducive to the judgment of patients' conditions and the development of treatment plans.
