This is a story that my driver told me:
6 years ago, when he was 18, he fractured a leg playing soccer. He was taken to the hospital, and they gave him an spinal anesthesia, in order to work on his leg, put the bones in position and then put the cast, that covered the entire leg, from toes to the crotch.
After the cast was fixed in his leg, he realized that he was't capable of urinating, his bladder was full, but he had no sensation down the waist, and couldn't pee, even if he made his effort in the methalic pot. The female doctor told him that if in a half hour he didn't pee they would have to put a catheter or the bladder would explote and he would die, so, after half hour they performed that procedure. The nurse took his penis, cleaned it and introduce the long methalic catheter, he said it was maybe 1m long. He said it was the worst sensation ever, even if he didn't feel any pain (because he was still under the spinal anesthesia), but he felt so vulnerable, and was very afraid of any damage.
After that, he was in his home, but he was incapable of poop, everytime he tried, his leg was in pain, make any effort was terrible, so he didn't shit for a week. After a week he began to feel very sick, and start to have a kind of seizure. A cousin that is doctor go to visited him and told him that his colon was very constipated, and he was in a kind of intoxication. The doctor cousin gave him a shoot to calm his seizure, and recommended a diet of plenty fluids and light food. He also put him a suppository, which he said was a very embarrasing experience, as long as he felt very bad about putting something up his ass.
