Postoperative care measures for kidney cancer primarily include observing the patient's vital signs. After a radical nephrectomy for a large renal tumor, a significant amount of tissue is removed including the kidney, surrounding adrenal fat, and lymph nodes at the renal hilum, which results in larger surgical wounds and potentially more bleeding. Therefore, it is crucial to closely monitor for signs of bleeding and ensure that transfusions and fluid administrations are unobstructed. Secondly, careful observation and management of the wound drainage tubes are required. Thirdly, for radical nephrectomies, once the patient is past the anesthesia phase and the blood pressure is stable, a semi-reclined position can be adopted. Patients who have undergone partial nephrectomy should remain in bed for one to two weeks to prevent further bleeding, and kidney functions should be monitored. Additionally, attention should be paid to symptoms such as breath holding and difficulty in breathing. Postoperative feeding should commence once gastrointestinal function is restored; thereafter, nutrition should be enhanced to boost bodily resistance. Calming medications may be appropriately used to ease pain, facilitating movement, effective coughing, and expectoration.
