IVP结合DR在诊断肾脏下垂中的应用

目的探讨静脉肾盂造影（IVP）检查中结合DR透视在诊断肾下垂中的应用价值。方法本组6例患者先行常规IVP检查,后采用直立位观察肾脏、输尿管位置及形态变化,对比测量卧位和立位时肾脏位置的变化。依肾下垂程度分三度：下降至第3腰椎水平为Ⅰ度,至第4腰椎为Ⅱ度,至第5腰椎及以下为Ⅲ度。结果常规IVP检查,6例患者肾脏位置均未见异常,4例提示轻度积水。立位片显示双侧肾脏下垂4例,单侧肾下垂2例。其中Ⅰ度肾下垂2例,Ⅱ度肾下垂3例,Ⅲ度肾下垂1例。结论 IVP检查结合DR立位透视、摄片是诊断肾下垂以及分度的重要方法。

Application of IVP combined with DR for diagnosis of nephroptosis

Objective To assess the application value of IVP combined with DR for Diagnosis of Nephroptosis.Methods 6 patients with nephroptosis underwent intravenous pyelography（IVP）,following by DR in the erect position.IVP plain film of kidney were compared with DR abdominal plain films so as to observe the different location and shape of kidney as well as ureter in upright and horizonal positions.Nephroptosis were classified as 3 degrees.Degree I was for the kidney hilum locating at the lumbar 3 level,Degree II for lumbar 4 and Degree Ⅲ for lumbar 5 and below.Results The location of the kidney on the routine IVP film were normal in all cases,4 of 6 appeared as slight hydronephrosis.Bilateral nephroptosis and unilateral nephroptosis were respectively found in 4 and 2 cases on the upright position of DR films,2 cases for degree I,3 forⅡand 1 for Ⅲ.Conclusion IVP combined with DR is an efficient method for diagnosis and classification of nephroptosis.
