Diagnosis of kidney cancer

Kidney cancer is a type of cancer that occurs in the kidneys. Regardless of the size of the kidney cancer, about 80% of patients may not have any symptoms in the early stages. It is only during a general survey or a physical examination or B-ultrasound examination for other reasons that it is discovered that there is a space-occupying lesion in the kidney or a palpable abdominal mass. So what is the diagnosis method for kidney cancer?

(—) Clinical manifestations

Typical symptoms include painless hematuria, a mass in the waist or upper abdomen, and waist pain.

2. Laboratory examination

(1) CT examination: can show the size of the tumor and the degree of infiltration of adjacent organs

(2) Microscopic examination of urine: "Three cups of urine" and exfoliative cytology of urine can identify the site of hematuria.

(3) Ultrasound examination: It is easier to differentiate renal cancer from benign renal tumors, cysts, and hydronephrosis, but it is often easy to miss renal pelvis and ureteral tumors.

(4) X-ray examination: X-ray abdominal plain film, intravenous urography, retrograde cystography, abdominal aortography, renal artery angiography, intravenous renal parenchymal tomography, inferior vena cava angiography, and perirenal pneumatic angiography are all helpful in the diagnosis of renal tumors.

Urine lactate dehydrogenase determination and serum reactive protein examination can also be performed.

Through the above explanation, we know what are the diagnostic methods of kidney cancer. If there are patients suspected of kidney cancer, go to relevant regular hospitals for diagnosis and treatment.
