title: [Possibilities of polyposture methods in x-ray diagnosis of renal and ureteral calculi and associated complications].
abstract: A comprehensive radiation examination of 47 apparently healthy patients has ascertained that one of the angles formed by the renal lateral axis and the body's frontal plane (BFP) is 35-45 degrees and medially open, the second made by the long axis of the kidney and BFT is 28-32 degrees and caudally open. The densitometric findings from the X-ray films of 17 patients with ureteral calculi (UC) significantly suggest that a contrast medium rapidly moves to the dilated lower urinary tract due to changes in the relative position of the renal cavities against BFP. Twelve patients underwent separate studies of diuresis, glomerular filtration and tubular reabsorption in the supine position and in the position of the lower body dropped at an angle of 45 degrees (for 20-min periods). Excretory urography followed by measurements of the mean ureteral diameter was performed in 36 patients with dilated ureters and in 31 control subjects. There was a close correlation between the size of ureteral lumen and diuretic values and there was an inverse relationship to the magnitude of tubular reabsorption.
