Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The urethral pressure is measured with the standard urethral pressure catheter Microtip. After this measurement the urethral pressure is measured again with the new 7-channel catheter. The intervention is a part of a urodynamic evaluation for which the women are scheduled. Each measurement is taken once in each patient.

The microtip catheter is has 2 sensors (one in the bladder, one in the urethra) and is withdrawn through the urethra using a mechanical puller at a constant speed. Measurement take about 1 minute.

The 7-channel catheter has 7 individual sensors at 5 mm distance between each of them, size 8 French, flexible. It is not withdrawn. Measurement take about 1 minute.
