How to tell the difference between kidney cancer and renal pelvic cancer, which is more serious, ren

Kidney cancer and renal pelvic cancer are both common malignant tumors of the kidneys and are common causes of hematuria. If kidney cancer originates from the perirenal pelvis cortex and protrudes into the renal pelvis, it can resemble renal pelvic cancer, and renal pelvic cancer can also resemble renal cancer when it grows large and invades the renal parenchyma. Distinguishing between them is important to guide the clinical development of an effective protocol, because in the case of renal pelvic cancer surgery, the kidney and ipsilateral ureters are completely resected, otherwise only nephrectomy is performed.

1) The time when the tumor causes hematuria.

Renal pelvic cancer is a tumor that originates from the renal pelvis and is prone to necrosis and shedding, causing hematuria at an earlier time. Renal cancer originates from the renal parenchyma, and hematuria occurs only when the renal pelvis is invaded, so hematuria develops later than renal pelvic cancer.

2) Boundary between tumor and renal parenchymaKidney cancer is a tumor that occurs in the renal parenchyma, and the boundary between tumor and renal parenchyma is blurred. Renal pelvic cancer originates from the epithelium of the renal pelvis, and when it grows, it first compresses and then invades the surrounding tissues (a variety of tissues), so the boundary between the tumor and the renal parenchyma is often clearer than that of renal cancer, or there is a compression zone.

3) 90% of kidney cancers with tumor blood supply were high blood supply lesions, and the enhanced scan showed moderate to high enhancement, while the blood supply of renal pelvic cancer was less than that of renal cancer, and the enhanced scan showed low enhancement.

4) Tumor calcification.

8% to 18% of kidney cancers are accompanied by calcifications, which mostly occur within the tumor and can be irregular, patchy, spotty, and sandy. Renal pelvic cancer is less likely to cause calcification, and if calcifications are found, they are more likely to be coarse calcifications and more likely to develop tumor margins (which may be pre-existing kidney stones).

The difference between kidney cancer and renal pelvic cancer is that the location of occurrence is different, renal pelvic cancer occurs in the urinary system, and kidney cancer occurs in the kidney. The second point is that there are differences in clinical symptoms depending on the location. Patients with renal pelvic cancer will have ** naked blood urine in the early stage, and kidney cancer patients will have a certain degree of hematuria.

The prevention of kidney cancer should be based on the positioning of kidney cancer, which is mainly related to smoking, drinking, obesity, occupation, hypertension, radiotherapy, family history, genetics and other factors. At present, the only recognized environmental risk factor is smoking, so quitting smoking in time can reduce the risk. In addition, we should reduce the intake of high-fat and high-energy foods, keep exercising, control weight, avoid obesity, and control hypertension and diabetes.

Reduce the use of certain medications that can cause kidney cancer, such as antipyretics and pain relievers. Try to avoid the intervention of chemical carcinogens to reduce the incidence of kidney cancer.

Renal pelvic cancer and kidney cancer are both serious diseases of the kidneys, so which is more serious, renal pelvic cancer or kidney cancer?

The severity of renal pelvic cancer and kidney cancer cannot be directly compared, and it mainly depends on the stage of the patient with renal pelvis cancer and kidney cancer at the time of diagnosis. If it is early renal pelvic cancer or early kidney cancer, it can be surgically removed. After the operation, some patients with renal pelvic cancer need to undergo postoperative adjuvant chemotherapy, while patients with a section of renal pelvic cancer can be treated with the postoperative targeted drug Huai Ant.

Therefore, whether it is early renal pelvic cancer or early kidney cancer, there is a chance to get it after the above **. If renal pelvic cancer or kidney cancer is already at an advanced stage when it is discovered, it is a relatively serious situation and needs to be treated with conservative means of internal medicine.

Renal pelvic carcinoma is a type of tumor that occurs in the renal pelvis or calyceal epithelium, accounting for about 10% of all kidney tumors. Most of the disease is transitional cell carcinoma, and a few are squamous cell carcinoma and adenocarcinoma, the latter two account for about 15% of renal pelvic cancer, and their malignancy is much higher than that of transitional cell carcinoma. Transitional cell carcinoma can occur sequentially or simultaneously in any urinary tract site covered with transitional epithelium, so the diagnosis and treatment should be regarded as a whole, and a local transitional cell carcinoma cannot be treated in isolation.

About 70 90% of patients have the most important symptom in the early stage of clinical manifestations for ** gross hematuria, a small number of patients can cause lumbar discomfort, dull pain and swelling pain after the tumor blocks the renal pelvis and ureteral junction, occasionally renal colic caused by clots or tumor shedding, and it is rare for lumbar masses to appear due to fluid accumulation caused by tumor growth or obstruction, and a small number of patients have urinary tract symptoms. Patients with advanced disease develop anemia and cachexia.

The diagnosis method of this disease is basically the same as that of kidney cancer, a large number of repeated gross hematuria, and ureteral casts can be seen when the hematuria is severe. Examination is often unpositive, cystoscopy shows blood spurting from the affected ureteral orifice on cystoscopy, and tumor cells on urine cytology. B-ultrasound and CT examination showed parenchymal mass lesions in the renal pelvis, and intravenous pyelogram or retrograde pyelogram showed irregular filling defects in the renal pelvis or renal calyces.

Opaque positive nephrolithiasis can be confused with renal pelvic cancer, but the defective shadow of the former on the urogram is mostly garden-shaped or oval with smooth edges; In renal pelvic cancer, the edge of the mass defect is irregular, and urine cytology can detect cancer cells, and CT and B-ultrasound examinations also help in differential diagnosis.

Surgery is still the main treatment for renal pelvic cancer, which removes the diseased kidney and the entire ureter, including the part of the bladder next to the ureteral opening, to prevent the recurrence of tumors in the remaining ureters. The prognosis is also very different due to the large difference between the differentiation of cancer cells and the degree of invasion of the basal. The 5-year survival rate of well-differentiated and non-invasive renal pelvic tumors is more than 60%, but the survival rate after surgery for renal pelvic cancer is generally lower than that of renal cancer.

It has been reported that the addition of radiotherapy after surgery has a certain effect on improving the survival rate of imitation age.

The inner ear is located at the crest of the temporal bone and consists of a bony labyrinth and a membranous labyrinth. The bony labyrinth is a bony tunnel at the temporal bone crest, the cavity surface is lined with periosteum, and consists of the bony semicircular canal, vestibule, and ear.

Systemic symptoms: general malaise, loss of appetite, and weight loss are common systemic symptoms in cancer patients, and some patients may also be accompanied by varying degrees of fever, anemia, or hypertension. Manifestations of tumor metastasis: early metastasis often occurs in renal pelvicis cancer, and sometimes supraclavicular enlarged lymph nodes are palpable.
