How much is a normal person's urine volume?

The bladder capacity of normal people is about 500ml. When it reaches 300ml, it will produce urine intention. That is, normal people will urinate once when the bladder capacity reaches 200-300ml. Drunken and other unusual circumstances will cause urinary retention. At this time, the bladder capacity may reach more than 500ml. Doctors recommend not to hold urine. It is most appropriate to urinate when there is urine intention.
