Do you hold to pee twice as much if you merely own one kidney?

Do you hold to pee twice as much if you merely own one kidney?
no.. you pee when your bladder is full..
I only hold one kidney and seem to budge less than other population
No, your kidney produces the urine. Your bladder is the holding tank. The bladder will remain like size, no matter how lots kidneys you have. The amount of urine produced depends on your hydration status and the condition of your remaining kidney and cardiac output (strength of your heart).
I'd say they don't because how habitually you go pee is controlled by your brain by how much urine is within your bladder.
now that is to say outragerous, since there are 2 kidneys that filter blood which will produce more urine..however the bladder will still hold same amount of urine and if have one kidney..it will be more slower before going to bathroom...any way ancestors can live with one kidney short so called going to bathroom twice as much
