I had a catheter for two days mostly because I had this epidural thingy for pain medication and its potential side effect is to numb the lower half, including the bladder area so it was kinda necessary. It wasn't too bad, though, just kinda funny not having to use the toilet for that long. Removing the catheter, however... well, let's just say I'll live without ever having to experience that again, pretty uncomfortable couple seconds.
Due to the epidural thingy, the nurses also frequently checked my blood pressure (lowering the pressure as side effect) and foot movement (idk, just because?).
The only thing they really checked on me was the actual incision. Oh yes, I didn't have a laparoscopic operation, btw. My home town's hospital lacked skillz so it was done through all the stuff in the abdomen. Also the reason why I spent four days at the hospital.
I was actually in the OB/GYN ward (I suppose?) afterwards... It was a huge anxiety source for me beforehand but I called there and asked if I could have a one-person room or have a two-person room all for myself for obvious reasons. They were very friendly and I had the latter one. I didn't really move around the ward after the surgery so there weren't any awkward moments etc.
But yeah, one experience from the northern wilderness called Finland.
