What is a kidney nodule?

The kidney has nodules, which means that the kidney has a mass. The kidney has a mass, most of which are malignant, and only a few cases are benign. Benign cases are seen in renal adenomas or renal hamartomas. If B-ultrasound finds nodules on the kidney, further examination is needed. CT scan plus enhancement or MRI of both kidneys is needed to clarify the nature of the mass. If it is considered to be a benign tumor of the kidney, it can be reviewed regularly. If the review process found that the lump continues to grow, but also need surgery. If found that the lump does not grow, can not be treated. If suspected of malignant, or benign and malignant can not be distinguished, are to actively carry out surgical treatment.
