摘要
目的：白肾是急性完全性输尿管梗阻在静脉尿路造影上的一种征象，本文目的是探讨其形成机理和输尿管梗阻的成因。材料与方法：回顾性分析经手术和临床Ｘ线确诊的白肾２８例，２７例在常规静脉尿路造影后加照６０、９０ｍｉｎ延迟片，１０例还做了逆行造影，１例行大剂量静脉造影。结果：１７例为阳性结石，１０例为阴性结石，１例为血凝块引起输尿管急性、亚急性完全梗阻；在尿路造影片上表现为随造影时间延长，肾实质密度增高（即所谓“白肾”）。结论：白肾征的意义在于提示输尿管梗阻尚处于急性、亚急性期而肾功能尚未受损，应提请泌尿科医师及时予以解除。
Objective: The purpose of this article was to study the mechanism and etiology of ureteral obstruction.Materials and Methods: 28 cases of white kidney confirmed by surgery, clinic and X ray were retrospectively studied. Additional delayed urograms were taken at 60 and 90 minutes after routine IVP in 27 cases, additional retrograde pyelography were perfomed in 10 cases and IVP with large dose drip in 1 case.Results: Among 28 cases, 17 with nonradiolucent calculus, 10 with radiolucent calculus and 1 with blood coagulum were detected as the cause of acute or subacute complete ureteral obstruction. On IVP, the density of the renal parenchyme shadow became higher and higher with time extending (so called white kidney). Conclusion: The X ray sign of white kidney significantly suggest that the ureteral obstruction is still in acute or subacute stage while the renal function has not been damaged obviously, so that the urologist should be remined to release the obstruction in time to prevent the damage of renal function caused by delayed treatment.
