Differential diagnosis of right renal cancer

Renal cell carcinoma can occur at any age, but is most common in people aged 60 to 70 years. It is twice as common in men as in women. It usually occurs on one side, with no symptoms in the early stages. Painless hematuria is the earliest sign. Hematuria that grows at the edge of the kidney or outwards appears later or not at all. So what are the differential diagnoses for right kidney cancer?

1. TCM diagnosis: It mostly occurs in people over 40 years old. It is more common in men. The main symptoms are intermittent painless gross hematuria, but it is not an early symptom. When the bleeding is heavy, blood clots can be seen. There is dull pain in the waist, and a few cases are paroxysmal colic. A hard mass can be felt in the waist or upper abdomen. There may be fever, fatigue, weight loss, loss of appetite, dizziness, pale face, etc.
2. Diagnosis basis of western medicine: The diagnosis of renal cancer can generally be preliminarily diagnosed based on medical history, pyelography and ultrasound. Pyelography can show the displacement and compression of the renal pelvis and calyces. When it is difficult to make a diagnosis, CT and abdominal aorta and selective renal artery angiography can be used. Ultrasound and CT examinations can detect whether there are space-occupying lesions in the kidney and whether the lesions are cystic or solid. Arterial angiography can distinguish between benign and malignant tumors. CT can show the image of space-occupying lesions and the density of lesions more clearly, and can see whether there are enlarged regional lymph nodes and whether there are cancer thrombi in the renal vein and inferior vena cava. If the nature of the cystic lesion is still unclear after ultrasound or (and) CT examination, cyst puncture examination should be performed. The extracted fluid is observed with the naked eye, cytologically examined, and tested if necessary, and contrast agent is injected for cystography. The extracted fluid of benign cysts is transparent and light yellow, without malignant cells, and the cyst wall is smooth. If there is a tumor or tumor necrosis and liquefaction in the cyst, the extracted fluid will be bloody or thick, and malignant cells and filling defects can be found in the cyst.
