Yes. In kidney transplants, only one kidney is transplanted. Some people are born with only one kidney and others, for whatever reason (due, for example, to obstruction by a kidney stone), suffer the failure of one kidney, but they can still live a normal life.
However, this kidney needs to be preserved after surgery. Some care is therefore needed so that the kidney continues to function and the risk of chronic kidney disease is lowered.
For example, it is necessary to control blood pressure and potential diabetes, which can lead to lower kidney function.
Lower kidney function can also be a risk factor for cardiovascular disease.
