I was only born with one, was 35 when I found out. No negative impact so far but kidney stones could cause a serious issue. My dad is the same, he was 55 when he found out. He started dialysis when he was late 70s. Not sure having two would make a difference though as we’ve always had just one so our 100 kidney has always done the work of 2.
