摘要
目的探讨运用彩色多普勒超声预测肾积水患者肾功能可复性的临床价值。方法临床收治的重度肾积水患者62例，共70只患肾，静脉尿路造影（IVU）2h均不显影，利用彩色多普勒超声分别测定梗阻解除术前及术后2—3个月内的肾内动脉血流阻力指数（RI）和肾实质厚度，根据梗阻解除术后2—3个月内IVU2h内患肾有无显影，分为肾显影组（55只）、肾无显影组（15只），分析彩色多普勒超声指标与肾积水肾功能可复性之间的关系。结果梗阻解除术前肾显影组、肾无显影组R1分别为0．73±0．06、0．82±0．01，肾实质厚度分别为（0．45±0．08）、（0．23±0．09）cm，2组间各项指标比较差异均有统计学意义（P〈0．05）。采用正态分布法进行界值判断，以95％上限为界，肾皮质厚度为3mm（准确度为84．5％、灵敏度92％、特异性80．9％），RI值为0．81（准确度为81．4％、灵敏度67％、特异性87．6％）。结论彩色多普勒超声指标RI和肾实质厚度可以反映积水肾的肾功能损害程度并可作为临床上预测肾功能可复性的客观指标。
Objective To explore the value of color doppler ultrasonography in evaluating renal function reducibility in patients with severe hydmnephrosis. Methods Sixty-two patients including 70 renals were involved in this study. Intrinsic artery of kidney resistant index and thickness of renal parenchyma were measured before operation and 2 - 3 months later using color doppler ultrasonography respectively. These patients were divided into two groups： nonvisualization（ 15 kidneys） and visualization （55 kidneys）group, according to results of urography in 2 hours after operation. The relationship between these ultrasound markers and renal function reducibilitywas analyzed. Results RI in visualization and nonvisualization group were 0.73 ± 0.06,0.82 ± 0.01 ,respectively. Thickness of renal parenchyma in two groups were 0.45 ± 0.08cm,0.23 ± 0.09cm respectively. There were significant differences between two groups. Regarding thickness of renal parenchyma being 3mm as criteria of reducibility , Accuracy, sensitivity and specificity were 84.5% 92% ;80.9%. When RI was 0.81, accuracy,sensitivity and specificity were 81.4% 67% ; 87 .6% in judging reducibility. Conclusion RI and thickness of renal parenchyma could reflect the degree of renal function damage, furthermore, predict renal function reducibility in patients with serious hydmnephrosis.
