I had a catheter and a drain.  I had the laparoscopic/robotic surgery.  The catheter was no big deal when it was removed, but the drain was more painful to take out.  They do it quickly!

I had a drain and a nasal gastric tube (tube that went through nose to stomach) for most of my many surgeries.  There were a few where I didn't have the tube.  I always get nauseous after surgery and one time I didn't have the tube I was vomiting like crazy .  Not too fun or even good after our surgeries!   They use these during surgery, and the surgeon had it removed.  But sadly, they had to put a tube back IN when I was conscious and I wouldn't wish that on anybody. 

On subsequent surgeries I learned a bit. (This is just for me.)  I tell them to please not remove the tube after surgery until I've past the worst of the vomiting.  Yes that means having an NG tube in your nose for a while.  BUT IMHO, way better than vomiting and have it put back in.  Not an easy thing for the nurses or the patient to go through

One of the reasons I think I was extra nauseous was because of caffeine withdrawals!   I was drinking about three cups a day and the withdrawals caused me pretty bad headaches which made me nauseous.  I'd highly recommending tapering off from caffeine for weeks before a surgery for those that may have an issue.  Literally, Cleveland Clinic gave me caffeine in my IV to help.

Best wishes!
