COMPUTER ANALYSES OF UROMETROGRAPHIC & ELECTROURETEROGRAPHIC DATA

UTETERAL FUNCTION AT VARIOUS URINE FLOW RATES

Abstract

Attempts were made to analyze through a computer system data concerning urometrograms of an apparently healthy man as well as electroureterograms of healthy dogs with the following results:
1. On urometrographic analysis in an apparently healthy man, discharge intervals of action potentials averaged 23.3sec., contracting pressure 27.91mmH₂O and resting pressure 11.77mmH₂O respectively at a constant urine flow.
2. In normal dogs with constant urine flow, discharge intervals averaged 2.945sec., travel rate 30.65m/sec. and amplitude 0.87mV respectively as electroureterographic recordings revealed.
3. In normal dogs, action potentials of the ureter continuously increased or decreased in discharge interval or, otherwise, suddenly at a different pace, depending on the degree of increase in intraureteral pressure as urine flow increased.
