Urethral catheterization significantly alters uroflowmetry results in both males and females. Performing uroflowmetry immediately after catheterization is not recommended due to unreliable flow rate measurements.

Area of Science:

Urology
Diagnostic Imaging

Background:

Uroflowmetry is a key diagnostic tool for lower urinary tract symptoms.
Urethral instrumentation, such as catheterization, may impact uroflowmetry measurements.

Purpose of the Study:

To evaluate the effect of urethral catheterization on uroflowmetry parameters.
To determine the reliability of uroflowmetry performed immediately after urethral instrumentation.

Main Methods:

Uroflowmetry was conducted on 129 patients before and after urethral catheterization.
Analysis focused on maximum flow rate, mean flow rate, and voided volume.

Main Results:

Urethral catheterization significantly altered uroflowmetry measurements in all patients.

Related Experiment Videos

Males showed decreased maximum and mean flow rates; females showed decreased maximum flow rate only.

Voided volume increased in females, while residual urine decreased, but changes were not significant in males.

False positive results occurred in 32% and false negative in 11% of post-catheterization tests.

Conclusions:

Urethral instrumentation markedly affects uroflowmetry readings.
Uroflowmetry is not recommended immediately following urethral catheterization due to potential inaccuracies.
