[|Human|] my son 9 years old, no pee from this noon, now is 12:oo am, because he said it s very hurt to pee, so he has to hold it, can t pee. I m going to take him to see the doctor, now he is in sound sleep, it s OK to wait until tomorrow? How long usually a 9 years old won t pee, but still ok for the kidney? Thanks
[|AI|]  Hi, Thank you for asking question on Chat Doctor. It is definitely a matter of concern if the child do not pass urine for 12-24 hours. AS the child is sleeping probably there is no distension of bladder. You can safely wait till tomorrow. Kidney damage will occur if there is no urination for more than 24- 48 hours, inspire of Chat Doctor. First there is distension of bladder and back pressure leading damage to kidney. Hope this answer will serve your purposeless feel free to ask any more queries if requiredTake care
