My daughter (who has autism and other special needs) gets very anxious about passing urine and therefore tries to go as little as possible (she will sometimes go 24 hours without passing any)- I’m quite worried about this and I was talking to my mum today who says that this won’t cause a urine infection (she has had a few urine infections in the past year) and most likely won’t do her any harm so I shouldn’t worry. I was just wondering if anyone knows if holding in urine for extended periods can actually cause a uti and also if I am being unreasonable/unnecessary in worrying? Thank you
