My my Monkey on my back

I'm 60, in a nursing home, hav ms, my bladder shut down. 8 years ago I got a suprapubic catheter, great going. A year ago the sediment appeared and now I have to get a new catheter every 5 days. This morning I started to wet myself, the catheter was FULL of sediment. Where does the sediment come from? There is a never ending supply of it!!!!1
