The most important purpose of the follow-up visit is: to check for recurrence, metastasis and neoplastic tumors. The competent physician may refer to the guidelines of urology (CUA) for follow-up treatment related to the following contents, taking into account the local medical conditions and the patient’s condition. For the first follow-up, it can be performed 4-6 weeks after surgery, mainly to understand the renal function, recovery status after blood loss and any surgical complications. For patients who underwent renal unit preservation surgery, a renal CT scan was performed 4-6 weeks after surgery to understand the morphological changes of the kidney for future review. General routine follow-up includes: 1) medical history questioning; 2) physical examination; 3) routine blood and blood biochemical examination: liver and kidney function as well as blood biochemical indexes of abnormal preoperative examination, such as abnormal preoperative blood alkaline phosphatase, usually need further review because recurrent or persistent abnormal alkaline phosphatase usually indicates distant metastasis or residual tumor. If there is abnormal elevation of alkaline phosphatase or (and) symptoms of bone metastasis such as bone pain, bone scan is needed to further understand whether there is bone metastasis; elevated alkaline phosphatase may also be a manifestation of liver metastasis or paraneoplastic syndrome; 4. Chest X-ray (frontal and lateral). If economic conditions permit, it is best to perform CT scan of the chest; 5. Ultrasound examination of the abdomen. Patients with abnormalities found in abdominal ultrasound examination, patients with preserved kidney unit surgery and patients with T3-T4 stage kidney cancer after surgery need to have abdominal CT scan examination, which can be performed once every 6 months for 2 years, and later depending on the specific situation. Follow-up time frame for each stage of kidney cancer: ① Early stage kidney cancer (T1-T2): follow-up every 3-6 months for 3 consecutive years, and annually thereafter; ② Advanced stage kidney cancer (T3-T4): follow-up every 3 months for 2 consecutive years, 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 once every 6 months. MRI of the central nervous system, urinary catecholamine measurement, ophthalmology and audiology should be performed once a year. ④ For patients in the low-risk group, CT scans of the chest should be performed once a year for 5 years after surgery, and CT examinations of the abdomen should be performed at 24 and 48 months after surgery. In contrast, for patients with regional lymph node metastases, CT scans of the chest and abdomen were required at 3, 6, 12, 18, 24, and 36 months postoperatively, and annually thereafter.
