When I was first diagnosed with urine retention I was instructed to buy reusable red rubber catheters. After the use of the catheter I was instructed to wash it with dial soap and let it air dry on a paper towel.
Only to find out later that other countries and even some major medical facilities
DO NOT RECOMEND REUSING INTERMITTANT CATHETERS BECAUSE OF INFECTION.
I think we as a community need to demand better care.
