I just underwent significant abdominal surgery to re-repair a ventral hernia.
I had a catheter for two days.
Somewhere between the catheter, the pain meds and a new body shape i was leaking worse than after my original ralp!! 4 or 5 pads a day
Ive been walking and kegeling and have it back to a pad a day, mostly for coughs/sneezes etc…
So yes i believe they continue to be useful.
