This sounds so strange to me Daphne. Did the new doctor give you a diagnosis as to WHY your bladder isn’t emptying completely? There could be many reasons. As to self catheterization…go to the main Mayo Clinic page and put “self catheterization” in the search box. Many posts about it came up when I did that. You might want to join a second chat group about self catheterization and chat with others in that group about their diagnosis and why they are now self catheterizing. Did you make an appointment with a nephrologist yet?
