| Abstract: | The experience with dynamic renal scintigraphy has shown its high informative value and safety in evaluating the degree of intrarenal urine outflow disorders. However, failure to make an objective assessment of ureteral patency considerably limits its study. The set of studies, which is given in this paper, is devoted to precisely this, highly urgent, problem. The authors have developed an original procedure for diagnosing impaired urine outflow along the ureters during dynamic renal scintigraphy. The visual and digital characteristics of normal and impaired urine outflow in the supravesical segment are defined. The criteria characterizing severe impairments of renal urine derivation along the ureters are denoted. Risk factors for urine outflow disorders are identified in patients with cancer of the cervix uteri, who receive various treatment modalities. |
