What are the risk for a chronic obstructive pulmonary disease (copd) patient having a radical nephrectomy?

Depends: COPD exists with varying severity, and most patients can have surgery with no significant increased risk. If COPD is very severe, or there is significant chronic sputum production, surgical risk is higher, but experienced teams of surgeons, anesthesiologists, nurses, and respiratory therapists can help mitigate the risk. One important thing you have control over is pre-op smoking cessation.
