for my foley, I take a large diaper pin and pin the catheter to the inside of my underpants near where the drain tube y’s from the balloon port. The catheter is flexible and long enough that this seldom causes a problem. The catheter comes out of the penis and makes a gradual bend downward into my underpants. I pin mine on the lower left side of the underwear. You could always discuss this with your surgeon’s nurse.
