Basic Sensations Coming From the Bladder

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.
