Brief Summary:

A major complication in studies to identify the nature of bladder sensations is language. It is difficult, if not near impossible, for the lay person, with no knowledge of physiology, anatomy or pathology, to put into simple terms a description of basic visceral sensations. Therefore, before the investigators can speculate about the detailed mechanisms generating sensation the investigators must overcome this language and communication difficulty. This will be addressed in the present study.

There are important reasons why the investigators must identify the mechanisms generating the different sensations as the bladder fills. One of them is that these are basic physiological mechanisms which need to be better understood.

  1. description of bladder sensations

    The primary objective of this experiment is to address how medical students and patients with OAB describe the sensations they feel during the filling phase of the bladder.

    Primary objectives

    • To put into simple terms a description of basic visceral sensations coming from the bladder
    • Describe the pattern of normal sensations during filling

Patients with overactive bladder


Inclusion Criteria:

Healthy volunteers

  • Healthy students from The University of Maastricht well versed in Dutch.


  • Patients with OAB diagnosed by their urologist using the criteria of more than 8 micturitions on three consecutive days. Before the start of any anticholinergic or other therapy.
