can bladders actually shrink? like i found out during surgery recovery due to a blocked catheter that was ignored by a nurse on shift, the following shift nurse who actually acknowledged my point that itw as blocked said my bladder held 3x the normal bladder limit, but now due to a change in urethral gravity i cant sleep longer than 7 hours without my bladder deciding its time for action. Am i just doomed to a super sized bladder that wont ever see its full potential again or might it shrink from nonusage?
