What is the mean of Uroflowmetry

The Uroflowmetry is a diagnostic procedure, in which the Harnausfluss during urination (micturition) were measured. It serves the objective determination of urinary symptoms and is one of the basic research in urology. In the following measurement values ​​are recorded:

     Harndurchflusses amount of time per unit (ml / sec)
     The duration of bladder emptying (s)
     The maximum urinary flow rate Qmax (ml / sec)
     The mean (average) urine flow (ml). It is calculated (micturition volume divided by flow time).
     The increase in flow time (sec). The time from the beginning to the maximum flow.
     The total micturition volume.

The calculated values ​​are in a flux curve umgesetzt.Diese flow curve shows a typical course of certain diseases.

Prerequisite for a properly executed measurement is sufficiently filled bladder. The interested party must wait micturition (urination) until he verspührt a strong feeling of pressure. Then he should urinate with pressure in the previously established diagnostic instrument, until the bladder is emptied completely. He should be unobserved if possible. After emptying the bladder with the help of an ultrasound residual urine found in the bladder and accurately measured.

When interpreting the following guideline applies Uroflowwerte:

     Maximum flow at 10 ml / sec. : High probability of obstruction
     Max flow between 10 and 15 ml / sec. : Further clarification is required.
     Maximum flow of 15 ml / sec. : No obstruction.
