Hello, remove a kidney. If a kidney works normally, it will generally not affect the work. If your kidney function is normal now, then you are equivalent to a kidney now, and you will be more vulnerable than the average person. For example, the dosage of drugs should not be too large and should not be used indiscriminately, because most drugs need to be excreted from the kidneys. Protein also can't eat too much, because it will increase the burden on the kidneys. It is recommended to check renal function and urine routine regularly. Pay attention to rest and avoid using nephrotoxic drugs. The above comments are for reference only.
