The purpose of this study is to ascertain whether the urinary (turbulent) flow really causes the sounds during micturition in humans. For this purpose the artificial bladder and urethra, which were made of silicon rubber (3M Co. Minnesota, U.S.A.), were used. The manometric device was attached to the bladder to measure the intravesical pressure. Outside the bladder neck a prostate like protrusion surrounding the urethra was made. A microphone was attached to this protrusion to detect the sound. A recording system was also adopted. The bladder was filled with 200 ml of sterile eater. By pressurising the artificial bladder at 100 cmH2O, the water passed through the urethra. During this artificial voiding the sound detection was undertaken. At the same time uroflowmetry was also performed. It was demonstrated that sound spikes were recorded whenever water in the artificial bladder passed through the artificial urethra.
本研究的目的是确定排尿时尿液（湍流）是否真的会产生声音。为此，使用了由硅橡胶（美国明尼苏达州3M公司）制成的人工膀胱和尿道。压力测量装置连接到膀胱以测量膀胱内压力。在膀胱颈部外侧制作了一个围绕尿道的前列腺样突起。在这个突起上连接一个麦克风来检测声音。还采用了记录系统。膀胱中注入200毫升无菌水。通过以100 cmH₂O对人工膀胱加压，水通过尿道。在这种人工排尿过程中进行声音检测。同时也进行了尿流率测定。结果表明，每当人工膀胱中的水通过人工尿道时，都会记录到声音峰值。
