[Effects of iodine contrast medias on the function of transplanted kidneys].

The effects of renal arteriography (n = 94) and intraveinous urography (n = 137) on renal function were studied in 80 renal transplant recipients. No damage to renal function was noted when these investigations were performed in patients with normal renal function. In transplanted patients with previous renal insufficiency, arteriographies, even selective, did not seem to be more dangerous than highdose urographies. The degree of seriousness of nephrotoxic accidents seems to be increased when the iodine dose is more than 1 g/kg b.w. and when the investigations are repeated within short intervals.
