Say you were normal young man of 20, with no kidney or BPH problems.
Say you decide to hold your urine until 500 ml to 1000 ml all the time.
You will create permanent damage to the muscles of the bladder
as they will be over stretched for years, they will have scar tissue,
unable to function properly, until one day they cannot squeeze all the
urine out of the bladder when you go pee.
You can damage your bladder by holding too long. Once a day
when you are asleep is enough to hold to 500 ml -600 ml.
But if you do this all the time when you are awake, you are asking for
problems as you get older because our bladders lose elasticity with age.
