What if a man only has one kidney?

Kidney as a very important internal organ of the human body, can discharge the waste of human metabolism, but also has endocrine function. There are two kidneys in the human body, under normal circumstances can function normally. However, due to kidney disease or trauma, tumor, need to remove a kidney. Unilateral kidney is based on two basic premises, namely stable metabolism and good renal function. It is best to go to the hospital for a related examination, such as nephrogram or glomerular filtration rate determination. If the remaining kidney is normal, renal function is normal, and there is no impact on the human body. It will not affect human health.
