Overview

Objective:
The objective of this study was to determine the intraindividual variability of uroflowmetric measurement in women with normal lower urinary tract function.

Design:
Prospective study.

Setting:
Departure of obstetrics and gynecology University Hospital and Medical Faculty Ostrava.

Methods:
35 women without lower urinary tract dysfunction were enrolled into the study. Every subject uderwent 3 uroflowmetric examinations. We processed all numeric results.

Results:
We assessed maximum and average urine flow rate – Qmax, Qave, voided volume – VV, corrected maximum urine flow and corrected average urine flow rate in every of 105 uroflowmetric´s measurements. We did not find any statistically significant difference for evaluation of intraindividual dispersion in studied parameters.

Conclusion:
Intraindividual variability of uroflowmetric´s measurement in healthy female subjects is low. One uroflowmetric´s measurement is adequate for assessment of uroflowmetric´s parameters..

Keywords:
uroflowmetry, intraindividual variability, lower urinary tract
