The first time I heard the terms “paruresis” and “parcopresis” was in the mid-1980s at a plumbing code hearing. In those days, there was no Google to look up the words. I listened to the chief plumbing inspector from a Midwestern state explain why this was an important issue in the plumbing profession.
Paruresis is often called shy bladder syndrome. If you do Google the term, you will find that it is identified as a social phobia, second only to the fear of public speaking. It is when an individual has a difficult time urinating when other people are around, or when there is inadequate privacy. From my further research, there are different levels of paruresis, wherein the most severe case, an individual cannot urinate in a public toilet room.
