Abstract:
:In real-time ultrasound examinations of six women, jets of urine were noted to enter the bladder during the filling phase. The jets appeared at irregular intervals, and each jet lasted from a fraction of a second up to three seconds. The ureters functioned independently of each other. The flow characteristics of the urine jets were examined with a pulsed Doppler system, and Doppler wave spectral analysis was performed. Possible causes for the ultrasonographic appearance of these jets and their clinical relevance are discussed.
