The main purpose of follow-up is to check for recurrence, metastases and new tumors. The first follow-up examination can be performed 2-3 months after surgery to assess renal function, postoperative recovery status and any surgical complications. Routine follow-up includes: ① history and physical examination; ② routine blood and biochemical examination; ③ chest examination: X-ray or chest CT; ④ abdominal examination: abdominal ultrasound or abdominal CT; ⑤ renal function measurement: ECT (nephrogram and glomerular filtration rate measurement). The items to be reviewed should be selected according to the situation at each follow-up visit. The follow-up time limit for each stage of kidney cancer: ① T1~T2: follow-up every 3~6 months for 3 years, and annually thereafter; ② T3~T4: follow-up every 3 months for 2 years, and every 6 months in the third year, and annually thereafter; ③ After treatment of VHL syndrome: CT scan of abdomen and head should be performed every 6 months. ③After treatment of VHL syndrome: CT scan of abdomen and head should be performed every 6 months. MRI of central nervous system, urine catecholamine measurement, ophthalmology and hearing examination should be performed once a year; ④Follow-up after targeted therapy for advanced kidney cancer: follow-up every 4-6 weeks, CT scan every 6-8 weeks, and the follow-up plan should be adjusted appropriately according to the patient’s general condition, drug duration, dose, toxic side effects and other factors. The follow-up plan after kidney cancer treatment should emphasize individualization.
