[Assessment of the passage of urine in the upper urinary tract based on radionuclide renographic data].
A group of 516 patients was studied using the routine renographic method. It can be admitted that 3 min after registration of maximum radioactivity in the kidney the curve of the radionephrogram in the interval of 7 min and that of radioactivity in the cardiac area within the same time interval are similar. Proceeding from this supposition coefficients of intensity of hippuran comparative outflow from the kidneys (K), from the kidney and blood (D) have been proposed. Using K and D coefficients the criteria of an extent of urinary passage delay from the upper urinary tract were determined. It has been established that renal function increases with age; therefore, age should be taken into consideration while assessing renographic results. In nephroptosis due to kidney forward shift the renal function index is to be understated. Renography has been shown advantageous in the evaluation of urine function and passage before chromocystoscopy in cancer patients.
