A patient got out of catch lab for 900ml fluid in without pee out, but he was fine, ate his lunch in afternoon, I came in asked how he felt, he said he could have sex then, I heard it but I couldn't believe he said that to me, just asked back quickly what, he said it again, then I replied let me scan your bladder first. 這個笑話恐怕只有學醫的才懂了
