That's one area I have had lots of luck with. I've used a 16f for over 10-12 years. Though about 6 years ago I switched to the 16f IC (Silver Coated, Infection Control.) I change every 2 weeks. I never see sludge in it. Greg
---------------- how often do you guys change your catheters? I have a supra pubic and I always have a lot of sludge running through my catheter and consequently it plugs up. I can barely go two weeks without it plugging. I'm using an 18 French. What is the process of increasing up to a 20? Dan
