Whether 83 years old can tolerate bladder cancer surgery is determined by the patient’s own cardiopulmonary function, underlying disease conditions, physical conditions and other factors. Bladder cancer surgery is usually a general anesthesia surgery, which is more traumatic and takes a longer time. Post-operative complications such as bleeding and infection may also occur, and prolonged bed rest may cause lung infection. Overall, the surgery is risky and requires a certain level of physical fitness from the patients themselves. 83 years old is an elderly patient with a relative decline in cardiopulmonary function, but age is not a criterion for assessment, and a comprehensive assessment is needed in conjunction with the results of cardiac ultrasound, electrocardiogram, pulmonary function, lung CT, liver and kidney function. If the cardiopulmonary function is still good and there are no other disorders, bladder cancer surgery can be performed under close monitoring. For some patients with serious heart and lung diseases, the risk of surgery will be greatly increased, and they may not be able to tolerate the surgery, or they may have a long postoperative recovery time and increased complications. At this time, the pros and cons need to be weighed, and sometimes it may not be possible to perform bladder cancer surgery. When bladder cancer appears, it is recommended to seek medical treatment in time and standardize the treatment under the guidance of professional doctors.
