The urodynamic effects of benzilonium bromide (Ulcoban) were investigated. In 5 healthy subjects a decrease of the maximum detrusor pressure, maximum urinary flow and maximum intravesical pressure were recorded as well as in increase of the residual volume. A significant effect on pulse rate but no effect on systolic or diastolic blood pressure was found.
Von Garrelts' uroflowmeter, commercially available, was tested at different true flow rates and jet velocities. The impact geometry was varied. Results show that flow-rate recording with von Garrelts' uroflowmeter is little influenced by variations of these parameters, and the instrument can be recommended for scientific and routine clinical use.
