How does renal capsule inflate excessively to return a responsibility?

summary

The mass was located under the auxiliary edge of one side of the abdomen. It was oval in shape, smooth in surface and solid in texture. No tenderness, relatively fixed, unable to move; The first symptom of about 1 / 4 nephroblastoma is low back and leg pain, but in fact, most of the pain is not serious, and children can not express it, so most of them can not be detected by parents early; Occasionally, children may have sudden paroxysmal pain, most of which are caused by sudden bleeding in the tumor, excessive expansion of renal capsule or blood clot blocking the ureter. Children with nephroblastoma often have atypical gastrointestinal symptoms, such as nausea, vomiting and loss of appetite.

Hematuria may occur in one of every five children with nephrocytoma. Hematuria is the first symptom in about 10% of the children. It is generally painless and intermittent hematuria, with a small amount and sometimes accompanied by blood clots. In most cases, however, hematuria is a more advanced symptom. Children with nephroblastoma may have fever of different degrees, mostly intermittent, rarely reaching 39 degrees. There may be many children with mild to moderate hypertension, but because of neglecting to measure the blood pressure of children, it is generally unknown. In addition, there are poor appetite, mild emaciation, mental impotence, pale complexion and general discomfort and other symptoms. Laboratory tests showed hematuria and proteinuria, rapid ESR and mild anemia; But the renal function was normal.

Surgery is the most important treatment for nephroblastoma. When the mass is found, the necessary examination should be done, and the operation should be carried out in time after making a clear diagnosis. For huge tumors, chemotherapy or radiotherapy should be done before operation. Surgical treatment can reduce the spread of cancer cells caused by extrusion during operation. Nephroblastoma is sensitive to radiotherapy. Preoperative radiotherapy can reduce the size of the tumor, which makes the operation more convenient and safe. If necessary, postoperative radiotherapy can also be performed. According to the current statistics, at least 20% of the patients had metastasis when they visited the clinic, and 80% of them were pulmonary metastasis. Nephroblastoma mostly has multiple metastases in both lungs, which is very sensitive to radiotherapy. If combined with chemotherapy, the curative effect is more significant. Bone metastases are usually multiple lesions, that is, the use of high-dose chemotherapy and radiotherapy, rarely cured.

Excretory urography showed that the shape of the kidney was enlarged, and the renal pelvis and calyces were deformed, elongated, displaced or destroyed. In some cases, renal function decreased or did not develop at all, and large dose contrast medium was needed. There are scattered or linear calcification on plain film. Ultrasonography is helpful to differentiate hydronephrosis. CT examination is helpful to determine the extent of tumor invasion. It can also be used for the determination of serum erythropoietin and renin. If necessary, renal arteriography and 99mTc DMSA renal scintigraphy can be performed.

matters needing attention

The maintenance of Wilms tumor must be carried out in daily life. The early symptoms of Wilms tumor are not obvious, so maintenance and prevention are particularly important. 1. Try to find and eliminate the kidney tumor before it grows. The earlier the discovery, the better the effect. The kidney should be examined by B-ultrasound once a year. 2. Renal cell tumor has become one of the top ten male tumors. 3. It is very important to grasp the best opportunity of renal cancer treatment. About 90% of early renal cell carcinoma can be cured after standardized radical operation. 4. The most common renal tumors in adults are renal cell tumors, which mostly come from the epithelial cells of renal tubules. The most common renal tumor in children is nephroblastoma.
