Abstract
Introduction and hypothesis
The objective of this study is to evaluate the effect of transient catheterization on uroflow parameters.
Methods
Consenting women (ages 18–90) provided an uninstrumented uroflow pre- and post-indicated in urodynamic procedures. Voided volume, Qmax, and Qave were recorded for both uninstrumented uroflows. Uroflow curves were classified as “normal” or “abnormal.” Pre- and post-urodynamic uroflow data were compared.
Results
Thirty-five patients were included in the study. There was a statistically significant decrease in Qave from the pre- to the post-urodynamic uroflows from 14.71 to 10.55 ml/s (p = 0.012). Additionally, 28.6% of uroflow tracing patterns changed from “normal” to “abnormal,” whereas only one (2.9%) changed from “abnormal” to “normal” (p = 0.031).
Conclusions
This study showed a degradative effect of transient catheterization on uroflow parameters, suggesting that catheterization may cause more than simply a passive obstructive effect. Urethral stimulation due to catheterization may perturb detrusor urethral function, altering voiding and possibly filling performance.
