DSA(Digital Subtraction Angiography) is a valuable diagnostic imaging method in many clinical fields, including ranal-related conditions. Sixty four renal DSA examinations were performed in performed in 59 patient with renal -related diseases from Jan. 1984 to Dec. 1985. Summary of These were as follows: 1. Intraarterial(IA)-DSA is performed in 6 cases, intravenous (IV)-DSA in 58 cases. In 58 Examinations of IV-DSA, diagnostic image quality is obtained in 51 cases (88%). 2. In investigations of a possible renovascular etiology of hypertension, IV-DSA is a simple, safe, sensitive and accurate method. On screening for evaluation of renovascular hypertension, RSP should be replaced with IV-DSA, because IV-DSA is more sensitive and accurate and can detect not only anatomic change of renal arttery but also functional hemodynamic change. 3. IV-DSA is valuabel in diseases with morphologic changes of vessels. In characterization of a known renal mass, and evaluation of hematuria, sus ected aneurym and renal trauma, IV-DSA is very useful diagnostic imaging modality. 4. In evaluation of potential renal donors, IV-DSA is an accrate and safe method with 82.4% of accuracy. IV-DSA also is useful in follow-up of allograft recipients. 5. In investigation of diabetic nephropathy, glomerulonephritis, pyelonephritis, IV-DSA is little helpful. 6. The advantages of DSA are well known , particularly post-procedure process using computer programs is helpful for obtaining informations of hemodynamic change or time-sequence-curve of density etc. More technical improvement with this modality is required for improvement of the image quality and resolution. And more accumulation of clinical experience is required in order to increase the diagnostic accuracy.
