PURPOSE
Uroflow and urodynamics are commonly used for demonstrating bladder functions. In this study we aimed to
demonstrate the effect of urodynamics catheter on uroflow parameters.
MATERIAL AND METHODS
This prospective study was performed from May 2014 until January 2015 on patients presenting to our pediatric urology
clinic with daytime or day and nighttime incontinance in whom urodynamics were indicated. Patients with neurogenic or
anatomic problems were excluded. Patients were chosen through simple randomisation and each patient had uroflow
measurements with urodynamics catheter (after 3rd filling), immediately after catheter removal and 1 week after
catheter removal. Uroflow parameters were compared between groups. Statistical analysis between groups was
performed using ANOVA and post-hoc Tukey analysis and p<0.05 was considered as significant.
RESULTS
Forty patients (18 male, 22 female) with an average age of 10.1 were included in this study. A statistically significant
difference between groups was observed for maximum flow (Qmax), time to reach maximum flow, flow time, voiding
time, average flow (Qave) and pelvic floor muscle activity while no difference was observed for voided volume or
postvoiding residue. While there was a difference between voiding patterns, this was not statistically significant.
CONCLUSIONS
This study has demonstrated a statistically significant effect that urodynamics catheter has on nearly all uroflow
parameters. Therefore, EMG-uroflow studies should be performed at a seperate time for patients undergoing
urodynamic studies.
