I had mine for almost six months, but it never weeped urine when they pulled it. My doctor did warn me that it might for the first day or two. I had a fair amount of proud flesh around mine. They’d burn it off with silver nitrate at every catheter change, but it would come back in a couple of weeks.
I don’t blame you for keeping the suprapubic. As much as I hated having it, I felt secure knowing it was there.
