Kidney tumors are divided into benign tumors and malignant tumors. Hamartomas, cysts, etc. are all benign tumors. Renal pelvis cancer and kidney cancer are malignant tumors. Different in nature. The severity is very different. Treatment methods are also very different. So, how to find kidney tumors. And how to choose treatment methods?
Pay attention to the “triad of kidney tumors”
Pain, hematuria, and masses are regarded as the “triad of kidney cancer.” But not all patients will have such symptoms, so the most scientific way is to use medical examinations to find kidney tumors.
Ultrasound inspection is the most basic inspection method, and its advantages are specific, sensitive, cheap and convenient. Through ultrasound screening, and then through enhanced CT to confirm whether there is a tumor and the size, location, nature, extent, and metastasis of the tumor. On the one hand, imaging examination can find the most obvious evidence, on the other hand, it can also scientifically evaluate tumor staging, providing a basis for subsequent scientific and reasonable selection of treatment methods.
If the diagnosis of ultrasound and CT is difficult, renal angiography and MRI (magnetic resonance) can be used to assist. Digital subtraction technology can clearly show the distribution of blood vessels and the benign (or malignant) nature of tumors in 80% under non-invasive conditions, providing a reference for the implementation of nephron-preserving radical renal cancer surgery. Currently, kidney tumors over 1 cm can be screened by ultrasound.
Diverse, vary
kidney tumors derived from renal parenchymal cells while, but it can grow invade surrounding tissue, such as. Renal pelvis, renal blood vessels, peripheral lymph nodes, etc. Kidney tumors can also metastasize to more distant organs, such as liver, lungs, etc., and then produce metastatic tumor foci. Currently curative. Nephrectomy is still a treatment. One of the most basic ways of renal malignant tumors. The parts removed by the operation are. Perrenal fat, fascia, renal pedicle lymph nodes and upper ureter. For those that have been transferred. Kidney cancer should also be removed to reduce tumor burden and improve the efficacy of subsequent treatment.
For both kidney cancer, isolated kidney cancer, one side. Kidney cancer was complicated by the contralateral side. Kidney failure and one side. Kidney cancer is complicated. Patients with severe renal insufficiency, or for chronic disease. In patients with kidney disease, nephron preservation surgery has extraordinary value. On the one hand, all tumor lesions can be removed by surgery; on the other hand, it will be as normal as possible. The renal parenchymal units are preserved to avoid uremia and. Kidney insufficiency. But not all. It can be implemented for kidney cancer patients. Kidney preservation surgery, this type of surgery is usually only suitable for lesions less than 4 cm in diameter and not exceeding. Tumors on the upper and lower poles or edges of the kidney.
For isolated and larger ones. Kidney tumor, but at the same time away. Near the center of the kidney. Kidney cancer patients, if conditions permit, can perform isolated workbench surgery, and perform autologous surgery after the tumor is removed. Kidney transplantation. For such insurance. Kidney surgery has very high technical requirements, and the requirements for surgical indications are also extremely strict.
1. Laparoscopic surgery for kidney cancer. The requirements, scope, efficacy, safety and openness of laparoscopic radical renal cancer surgery. The requirements for radical renal cancer surgery are the same. It can also be implemented through laparoscopy. Nephron preservation surgery only has a high technical standard for this. The current outstanding problem is that it cannot successfully carry out local cooling, thereby reducing the blood flow control caused by it. Nephron damage.
2. Minimally invasive treatment. Percutaneous puncture under ultrasound guidance or laparoscopic puncture, for smaller ones. Renal tumors are treated with cryotherapy and radiofrequency ablation. This type of approach is realized. The minimally invasive treatment of kidney cancer, the patient’s 5-year quality of life. Nephron preservation surgery is roughly equivalent, so it is currently. New trends in surgical treatment of kidney cancer.
3. Drug treatment. For the middle and late stages. In patients with kidney cancer, because they cannot be fully resected or tumor metastases have occurred, chemotherapy drugs such as medroxyprogesterone, interleukin-2 and interferon are usually used in the past, but the efficacy is not outstanding. In recent years, some new drugs for targeted therapy, such as sorafenib, sunitinib, mTOR blockers, etc., can successfully increase the progression-free survival time of patients. Although such drugs are expensive, they have high application value in clinical practice.
Scientific diet, reasonable weight
Studies at home and abroad have shown that some types of kidney tumors are closely related to hypertension, smoking, kidney disease, obesity and industrial pollution. In addition, some kidney cancers are related to genetic factors. Experts recommend that people pay attention to health, eat a reasonable diet, eat less fried foods, eat more fresh fruits and vegetables, maintain a reasonable weight, and prevent obesity. These healthy lifestyles can prevent the occurrence of some kidney tumors.
