[QUAD-L] SP Cath size

[greg]

Those with a SP cath, what size do you use? After how many years?   For about 15 years I used a 16F, but it started leaking around the cath itself, through the incision. So I changed to a 18F. But after only a few years, it's leaking again. Only at night. No idea why. Not blocked, not plugged, no junk in it, no sweating. In the morning everything is wet, night bag 1/4 full. So it's draing some, but not backing up causing AD or anything. I don't want to keep going up in size. How often do you go up in size?   Thanks, Greg
