A Comparison of Two Urinary Catheters of Different Lengths for Female Use, in Intermittent Catheterization

A Multi Centre, Single-blind, Randomized, Cross-over Study Comparing Two Female Catheters With Different Length in Terms of Residual Urine After Intermittent Catheterization

A study comparing a 10 cm catheter with a 7 cm catheter in a group of female patients who, on a routine bases, empty their bladder using urinary catheters, by measuring residual urine after intermittent catheterization.

The study personnel will conduct three bladder scans after each catheterization in order to obtain the mean residual urine volume. Each patient will catheterize herself two times with each product, i.e. a total of four catheterizations.

Diagnosis and BMI will be collected at visit 1 to assess whether the residual urine volume differs between these subgroups.

The hypothesis that the mean residual volumes were equal when using the 7 and the 10 centimeter catheters was tested by means of the Wilcoxon signed rank test.
