Overview
Brief Summary
The study is undertaken to investigate if the urethral microtrauma, caused by intermittent catheterization, differs between three hydrophilic catheters for intermittent catheterization, LoFric; SpeediCath (SC) and SpeediCath Compact Male (SCCM). The study is a prospective, randomised, cross-over, single-centre study.
Each subject will be randomized to use three different catheter types. Three catheterizations will be performed with each catheter type during one day, with at least two hours between each catheterization. The washout period between catheter switch will be at least one week.
The primary objective is to evaluate urethral microtrauma for three hydrophilic catheters with regards to hematuria after intermittent catheterization.
The secondary objectives are to evaluate urethral microtrauma for three hydrophilic catheters with regards to pyuria and subjective evaluation after intermittent catheterization.
The safety of the three catheters will be evaluated in terms of adverse advents, non-serious and serious, rated for causality.
The hypothesis that level of hematuria is equal after using different catheters will be tested using Wilcoxon signed rank test. The hypothesis will be rejected if the p-value is less than 5%.

Outcomes
Primary Outcomes
Hematuria
Time Frame: Approximately 2 hours after last catheterization
Blood in urine (measured by microscopic urine sediment evaluation) will be assessed at the first normal micturition after three catheterizations. Comparison will be made between study catheter/visit days.
Secondary Outcomes
- Hematuria(At first, second and third catheterization, approximately 2 hours apart)
- Pyuria(Approximately 2 hours after last catheterization)
