摘要
目的探讨白肾征的形成机理,并评价在输尿管梗阻中的诊断价值。方法搜集在常规静脉尿路造影(IVU)显示白肾征象的患者48例。所有患者均有急性肾绞痛、血尿等症状,并经IVU或手术确诊为结石或血凝块。结果30例为阳性结石,16例为阴性结石,2例为血凝块引起的输尿管的急性或亚急性完全梗阻;IVU表现为随造影时间的延长,肾实质密度持续增高(即“白肾”)。结论白肾征的意义在于提示输尿管梗阻尚处于急性或亚急性期,而肾功能尚未明显受损,此时给予及时治疗,可避免肾功能的进一步损害。
Objective To studies the mechanism of white kidney and evaluates the worth of diagnosis in urethral obstruction.Methods 48 cases of whiter kidney sign confirmed by IVP.male 30 and female 18,aged from 22- 56 years,mean：39 years .All cases have symptom of pain in kidney with or without haematuria . All of them were diagnosed as urethral calculus or blood coagulum. Results In 48 cases, 30 with nonradiolucent calculus, 16 with radiolucent calculus and 2 with blood coagulum were detected as the causes of acute or subacute complete urethral obstruction . On IVP, the density of the renal parenchyma shadow became higher and higher with lime extending （so called white kidney）. Conclusion The X- ray sign of white kidney significantly suggest that the urethral obstruction is still in acute or sub acute stage while the renal function has not been damaged obviously, so that we should release the abduction in time to prevent the damage of renal function.
