As a common and frequent disease in urology, renal tumors are traditionally characterized by hematuria, intra-abdominal mass and back pain as their three main symptoms. With the popularization of health checkups, more and more cases are detected by simple checkups; meanwhile, with the improvement of surgical techniques, partial nephrectomy with preservation of renal units is becoming an important option. In this issue, we show the health care related to renal tumors. Further down, it is the knowledge of diseases related to renal tumors, perioperative precautions and postoperative follow-up, so be sure to take a closer look and study the content carefully. As a surgical disease, surgery is of course the most important part of treatment, but it is not the whole focus of treatment. Perioperative treatment and postoperative follow-up are equally important, and postoperative health care knowledge can also affect the patient’s prognosis, so they are all quite important. The follow-up form includes the items that need to be checked and recorded in each postoperative follow-up, which must be strictly implemented and follow the doctor’s instructions in order to achieve the purpose of better postoperative monitoring. Postoperative follow-up of renal tumors is also quite a detailed matter, which needs to attract the attention of patients and their families. Strict and regular postoperative follow-up can detect possible problems at an early stage, which is easy to deal with, and allow patients to have a sense of health care instead of letting it go, which can maximize the consolidation of the effect of the surgery.
