Why I am diagnosed as kidney tumor without any symptoms? Typical symptoms of kidney tumor, such as hematuria, lumbago and abdominal mass, only account for less than 15% of all patients. Most of the patients are found by physical examination, at this time, the tumor is small and in the early stage of the disease, so the treatment effect is very good. If you undergo radical resection in time and follow up with our doctors regularly, the local recurrence rate after surgery is only 1%~2% and most of the patients can achieve radical effect. Therefore, you are lucky to a certain extent when the kidney tumor is detected in your physical examination! Please believe that when God closes a door to us, he will surely open a window at the same time. Second, how will the surgical removal of a kidney affect my life Surgical radical nephrectomy is the treatment of choice for limited kidney cancer, and it is ineffective against radiotherapy and chemotherapy. Each kidney in the human body is made up of one million mutually independent factories. Under normal circumstances, only 1/10 of the factories in each kidney are working, and the rest of the factories are in the state of “taking turns to rest”, that is, the kidneys have a strong reserve function. When we lose one kidney and half of another kidney, we will not have any conscious symptoms, and it will not have any effect on our life, work, labor, study and reproduction. In reality, some people are born with one kidney, and many people donate one kidney and kidney transplant patients have only one kidney, and they live like normal people. Therefore, surgery to remove one kidney will not have any effect on us. How should I follow up after the surgery? After kidney tumor surgery, we should follow up strictly according to the clinician’s requirements. Please remember the time of your supervising physician’s visit when you are discharged from the hospital. The first follow-up visit can be made at 4~6 weeks after the surgery, mainly to evaluate the kidney function, the recovery status after blood loss, and whether there are any surgical complications. For patients with preserved diseased kidneys, a renal CT scan will be performed 4-6 weeks after surgery to understand the morphologic changes of the kidneys for comparison in the future. Routine follow-up includes: ① history inquiry; ② physical examination; ③ blood routine and blood biochemistry examination; ④ chest X-ray; ⑤ abdominal ultrasound and SCT examination. The specific follow-up time is determined by the tumor stage, usually every 3 months for 2 years, every 6 months in the third year, and once a year thereafter.
