腎盂腎炎性高血圧の診断と腎動脈撮影

Abstract

In search for the cause of hypertension in a fifteen-year-old boy, quantitative bacterial culture of urine and urinary pus cell count revealed urinary tract infection. Although none of the examinations such as intravenous pyelography, renography, renal scintigraphy and renal function studies proved the presence of renal lesion, except for slight decrease in CPAH, renal arteriography definitely showed localized intrarenal arteriolar lesions, suggesting early stage of chronic pyelonephritis. Findings in selective renal arteriography suggesting renal ischemia are delayed opacification and nephrographic defects of affected part of the kidney. Causal relationship between pyelonephritis and hypertension was discussed.
