A normal kidney usually has about 1 million glomeruli, and two kidneys have about 2 million glomeruli.
Glomeruli are an important part of the renal unit and there are about 1 million renal units in each kidney, i.e. about 2 million renal units in two kidneys. Therefore, a normal person usually has about 2 million glomeruli.
The kidneys have a strong compensatory ability, such as trauma, kidney tumors, as a donor kidney transplant and other special circumstances, even if one side of the kidney is removed, the other side of the kidney can still meet the metabolism of the body.
If one side of the patient’s kidney is removed, the remaining kidney may not be able to fully compensate if there is underlying disease, etc., which may lead to different degrees of renal insufficiency. If patients experience discomfort, it is recommended that they go to regular hospitals in time and receive standardized treatment under the guidance of doctors.
