Attempts were made to analyze through a computer system data concerning urometrograms of an apparently healthy man as well as electro ureter ograms of healthy dogs with the following results: 1. On urometrographic analysis in an apparently healthy man, discharge intervals of action potentials averaged 23.3 sec., contracting pressure 27.91 mm H_2O and resting pressure 11.77 mm H_2O respectively at a constant urine flow. 2. In normal dogs with constant urine flow, discharge intervals averaged 2.945 sec., travel rate 30.65 mm/sec. and amplitude 0.87 mV 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.
