[The information value of rheography and loading tests in the functional assessment of the ureter (experimental research)].

Functional tests, using electro-ureterography, ureteral rheography, electromanometry and electromagnetic flowmetry in the presence of diuretic and perfusion load tests, were performed at surgery in dogs. Ureteral rheography is shown to be a valuable method for the assessment of ureteral motility (as evidenced by ureteral volume changes), and have certain advantages over other techniques so that it can be used clinically for preoperative functional assessment of ectatic ureters. Load tests are necessary at functional tests of the upper urinary system in order to assess the pattern of ureteral wall contractility and reserves.
