In a male. a stent will need to hold both the inner and outer sphincter open. I have been experimenting with catheters for quite a while but rarely keep a catheter stent in place for more than a day or so because of unreliable drainage when in bed. A regular catheter works fine. I use a drainage bag at night and have kept them in place for up to 6 weeks. My goal is a stent that is totally comfortable and drains at night when asleep. Not there yet.
If just using a catheter, it is easy to manage coming out of the shower, put some sort of clamp over the tube. When I wear a catheter to bed, it is always connected to a night bag. No mess.
I had the prostate and inner sphincter removed 10 years ago. I needed to use pads for 10 weeks after which things were prety well normal but different.
