title: A method to register a dynamic balance of the upper urinary tract.
abstract: Using a specially designed circuit with an UP-DOWN counter, a new method is briefly described for investigation of the upper urinary tract. It allows sequential measurements of the balance level between input and output of the pelviureteral system in animal experiments.
