Cutting out a kidney is major surgery.
Strictly speaking, clinically speaking, there is no such thing as major surgery versus minor surgery, and the size of the surgery is just a more general term. However, nephrectomy belongs to the surgery involving organ removal, the location of the kidney is relatively deep, often renal tumors or renal atrophy, etc. will involve nephrectomy surgery, no matter open surgery or laparoscopic surgery has a certain degree of difficulty.
In terms of surgical operation, the kidneys are located deeper, and the organs that can be neighboring around the left kidney include spleen and intestines, etc. The right kidney is surrounded by the liver, pancreas and other organs, and the kidneys may be adhered to the surrounding tissues and organs, making it difficult to separate them, and all these will affect the surgical operation, and increase the difficulty and risk of the operation.
If kidney-related diseases exist, timely consultation in regular hospitals is recommended.
