@srg_rik That's similar to what happened to my [ex-]wife...
She was in the hospital for back surgery -- a laminectomy, so nothing too major but still debilitating. IIRC the surgery was in the morning, and she had already been moved out of recovery to her room. However, by around dinner time, she still hadn't peed. She complained to me about it saying how uncomfortable and almost painful it was, but we agreed to wait until the nurse or doctor came by and we could ask about it then.
Fast forward to an hour later, still no pee, still no doctor or nurse. By this point she was in actual pain. I didn't know much about it, but I figured that if a bladder was full and kept getting fuller, it would burst or something terrible, and this pain was the body's way of telling us to hurry up. So I went and hunted down a nurse who came in to insert a catheter and solve the problem, when my more-observant wife asks, "Is that latex?" The nurse looks up. She looks at the catheter. Turns around, looks at the [BIG] sign on the door that says "Latex Allergy - no latex products to be used in this room", and finally nods. I was absolutely infuriated -- this seemed like such an obvious thing, to have it ignored was totally unacceptable to me.
She goes off to find a non-latex catheter. 2 minutes pass. 5 minutes. 10 minutes. In tears, my wife asks me to find out what's taking so long. I go out and find the nurse looking through cabinets but said she couldn't find a non-latex catheter. This was 2000, in downtown Chicago -- I felt like we were in the 3rd world trying to scrounge up supplies!
I thought getting mad and indignant might get her moving, or at least scared enough to go find someone competent. Nope. At one point she came in with some generic clear, plastic tubing saying "This is all I could find!" It didn't even have a rounded tip! It was like someone took some IV tubing and sliced it with a swiss army knife and suggested shoving that blunt/sharp end into my wife's urethra. I was not amused.
Eventually they found a non-latex catheter, the problem was solved (well over 1L but I don't remember the actual quantity), but to this day I still don't understand how the problem got so bad. When I went hunting for a doctor, it was like I was in a bad horror movie where everyone had just been taken -- there was no one around besides the station nurse who was unsuccessfully hunting for a catheter. Crazy.
