How to diagnose kidney cancer

Kidney cancer is a malignant tumor that mainly occurs in the kidneys. It is very harmful to health. Patients should not only pay attention to treatment, but also pay attention to the problem of kidney cancer inheritance. If kidney cancer affects the next generation, it will make patients feel guilty. Therefore, how to diagnose kidney cancer? The following is a detailed introduction.

1. CT examination: It can show the different densities of the tumor and the images of each layer, as well as the extent of the tumor's invasion or metastasis to the surrounding tissues and adjacent areas, providing an important basis for surgical treatment.
2. Ultrasound examination This examination is safe and convenient. It can detect early renal cancer of 1-2 cm in size that has no clinical symptoms. The accuracy of qualitative and localization is very high. Therefore, a simple B-ultrasound examination can be used for preliminary diagnosis.
3. Urinalysis examination: A small number of renal cancer patients only have microscopic hematuria but no visible hematuria. Microscopic hematuria may still exist during the intervals between hematuria. Therefore, it cannot be observed only by the naked eye and urine specimens should be sent for microscopic examination.
4. Urinary system angiography includes intravenous angiography and retrograde pyelography. When the cancer does not compress the renal drainage system, it is difficult to find anything with urinary system angiography. If the renal drainage system has been invaded or is blocked, it can show deformation, stenosis, elongation or filling defects of the renal pelvis and calyces. If the tumor is large and the damage is severe, it will not be obvious in excretory angiography.
