Vascular impressions on the renal-collecting system: diuretic cine-roentgenographic and angiographic study of 50 cases.
The vascular impressions on the renal pelvis and caliceal system may assume an important role in the study of some patients with hematuria and renal pain of unclear origin. 50 patients presenting vascular impressions on the calices and renal pelvis have been studied. In 12 patients (24%) the impressions were bilateral and in 38 (76%) unilateral: in 35 patients (70%) the right kidney was involved. In each patient the morphological pyelocaliceal variations have been studied with cine-roentgen-dynamic investigations and in 30 angiography was also performed. Interesting results have been obtained with cine-roentgenographic investigations during forced diuresis allowing differentiation between intrinsic and extrinsic lesions of the renal collecting structures, without resorting to more complex investigations such as angiography.
