Abstract

Observation that the size and force of the urinary stream are diminished in certain urologie conditions dates back many years. In 1932 Ballenger suggested that by periodically measuring the maximum distance from his feet that a man with a full bladder could eject his urine one might follow the effect of an enlarging prostate. Rose, Denny-Brown, Robertson, Langworthy, Kolb, and Lewis have studied by cystometric means the normal and abnormal physiology of the detrusor urinae muscle. Simons has likewise studied the physiology of both the internal and the external sphincters of the urethra. In 1940 Sigematu of Japan published a report on measuring the urinary flow by the use of a "slit-flow-clock" apparatus. Correlation between volume and time was not made. He expressed the opinion that the procedure was of little diagnostic value. Apparatus for measuring the minute volume of the urinary flow with a turbine or propeller were discarded
