What is the purpose of a nephrectomy?

The purpose of a nephrectomy is the surgical removal of one or both kidneys. This procedure is typically performed to treat kidney diseases, tumors, or other conditions that severely impair kidney function. In cases of kidney cancer, for example, removing the affected kidney can help prevent the spread of cancer cells. Additionally, nephrectomy may be indicated in cases of severe trauma to the kidney or for living kidney donation purposes. Understanding this procedure's context is crucial for medical professionals, as it informs how surgical interventions can impact a patient's renal function and overall health.
