Kidney disease can be acquired by men, women and children alike, and clinically, there is a difference between renal column hypertrophy and kidney cancer, and it is better to treat the disease properly when treating it. Patients want to treat these two diseases, they must know more about their symptoms, so that they can take preventive measures in the process of curing, treatment of these diseases must go to the hospital to find a professional doctor for diagnosis and treatment.

　　Kidney column hypertrophy is benign, and Kidney cancer is a malignant tumor. Renal column hypertrophy refers to the infiltration of the superficial cortex into the kidney column to form the kidney column. If congenital variation and individual kidney column loss are filled by the cortex, it is called renal column hypertrophy and does not affect the function of the kidney. It has no clinical manifestations and Pathological symptoms usually require B-ultrasound or other examinations to be found; kidney cancer is a common solid malignant tumor, which is also found through physical examination, and some have no obvious symptoms. The similarities between the two are substantial, low echo, and less blood flow, so it brings certain difficulties to clinical diagnosis. Kidney cancer less than 3cm and the renal column are difficult to distinguish. Kidney cancer mainly shows high echo, medium-sized kidney cancer sometimes shows low echo, and a few have liquefaction ranging from strong to weak. The boundary is relatively clear. It is recommended to go to a specialist hospital for examination.

　　 Preoperative diagnosis of kidney cancer depends on the results of imaging examination, and can provide the most direct diagnosis. At the same time, imaging diagnostic technology can also make accurate tumor staging in most cases, which is crucial for the choice of future treatment methods. Normally, imaging examination starts with B-ultrasound, and the diagnostic value of intravenous pyelography is relatively small. CT scan is the best method to understand the location, size, range, nature and metastasis of the tumor, so it has become the most reliable tool for diagnosing kidney cancer. Smaller tumors generally do not need to be checked for cavity group veins. If the patient has a large right tumor, vena cava or MRI should be performed. Now MRI is more commonly used to understand whether the tumor involves the vena cava and differential diagnosis. Cystoscopy should also be considered when there is hematuria. Renal arteriography has a certain role in the diagnosis of kidney cancer, especially selective or superselective renal artery embolization can be performed at the same time, which is conducive to the subsequent surgery.
