[Combination radiodiagnosis of the functional state of the urinary tract in cancer of the kidney]. / Kompleksnaia luchevaia diagnostika funktsional'nogo sostoianiia mochevydelitel'noi sistemy pri rake pochki.

The results of combined radiodiagnosis of the urinary system in patients with renal tumors before and after nephrectomy were analyzed. Investigations included excretory urography and renography with the processing of the results of measurements by a common algorithm and on the basis of 3 mathematical models of RP body transport. The results were correlated with the findings of biochemical blood and urine tests and pathoanatomical investigation of the removed kidney. Ample potentialities of renography for the detection of latent renal insufficiency in the preoperative period and for accurate and exhaustive assessment of function of the urinary system were shown.
