[The jet phenomenon in the bladder (author's transl)].
The jet phenomenon seen during entry of urine into the bladder is illustrated by the urograms of a number of patients. Its diagnostic significance is discussed. Experimental models and theoretical considerations have shown that the jet is determined by the kinetic impulse; for a 1:10 mixture of contrastmedium and water, the jet is visible at all jet diameters and jet speeds at the orifice provided flow at the centre of the jet has fallen to about 0.073 m/s. Transferring these findings to man, and bearing in mind the functional and anatomical peculiarities and pressure differences between the lower ureter and the bladder, it becomes apparent that this phenomen can be produced under physiological conditions.
