How to check complications of kidney cancer

Kidney cancer can be diagnosed based on the patient's medical history and family history. In severe cases, the diagnosis can also be based on the patient's physical condition. However, the most reliable and commonly used examination methods are imaging examinations and laboratory tests, which use machines to determine the patient's actual situation. There are several specific methods:

(1) Ultrasound examination: Ultrasound examination is simple, easy to perform, non-invasive, and has a high sensitivity in detecting kidney tumors. It is the preferred examination method. Due to the widespread use of B-ultrasound examination in clinical practice, the detection rate of asymptomatic renal cancer has been greatly improved. The sonogram of renal cell carcinoma can show abnormal renal section, localized echo abnormality in the renal parenchyma, and compression of the renal parenchyma. Color Doppler can show the blood flow of malignant tumors, and pulsed Doppler can effectively determine the blood flow of tumors.
(2) MRI: MRI has similar sensitivity and accuracy in the diagnosis of renal cancer as CT, and is superior to CT in showing the renal vein or inferior vena cava, surrounding organ involvement, and differential diagnosis of benign and malignant tumors. The theoretical advantages of MRI do not always provide much help in clinical diagnosis and treatment, so MRI is not a routine examination for patients with renal cancer. MRI examination is only considered when the data provided by CT and ultrasound examinations are not satisfactory for differential diagnosis and staging of tumors.
