腎血行動態からみた原因不明の一側性腎出血に関する考察

Abstract

30 patients of unilateral renal hematuria with normal findings on IVP were examined by 99mTcDMSA renal scintigraphy consisting of early and late images. Early image demonstrates cortical blood perfusion and late one does cortical functioning mass. According to the combination of abnormal findings of either early or late image, these patients were classified into 4 groups. Eighteen cases out of 30 showed abnormalities in both early and late images. Six cases revealed normal findings of both images, suggesting that this group should enter the category of so called essential renal hematuria. Bleeding side in those patients paralleled the lateralization of abnormal images. This study indicates that high frequency of cortical vascular abnormalities may exist in essential renal hematuria.
