Selective renal angiographies were performed on 15 cases of chronic advanced renal failure, who were admittedto the Hanyang University Hospital during the peiod of May 1976 to September 1977. The studies revealed as follows; 1. The cases examined were 10 male and 5 female patients. Age distribution was broad, most in fourties of age.2. The main symptoms were dyspnea, generalized edema, general weakness, nausea and vomitting. All of them wereanemic. The blood pressure was normal in 1 case, minimally hypertensive in 4 cases, moderately or severely in 10cases. Chest X-rayx revealed cardiomegaly in 9 cases and pulmonary edema in 6 cases. The average values o BUN were138.2mg/dl, serum creatinine, 20.82mg/dl, and hemoglobin, 6.89gm/dl. 3. Selective renal angiographies revealedabnormalities in all of the cases. The kidneys were shown to be small in 14 cases. With the size of the renalmasses and the shape of the renal arteries, the diagnosis of chronic advanced renal disease were possible in these14 cases. In one case, one of the kidneys was enlarged, a finding which would have been difficult to prove byother methods. The autopsy of this case revealed renal tuberculosis with hydronephrosis. 4. The diameter of therenal arteries was small in all the kidneys examined. The interlobar arteries were abnormal in shape in all thecases: pruing, 85.2%, tortuosity, 66.7%, spiraling, 96.3%, segmental stenosis, 22.2%, ectasis, 29.6%, and crowding81.5%. 5. The arcuate arteries and interlobular arteries were not able to be clearly delineated in most of thecases. The extrarenal vasculature was prominent in 44% of the cases. 6. The selective renal angiography may be avaluable method of screeing out the cases of reversible renal failure.
