Update After Urologist Visit

Got back from Dad's appointment with the urologist. They've decided to schedule his kidney surgery soon. It will be robotic (da Vinci) surgery. During the discussion, the urologist explained that the mass lacks clear boundaries, indicating a 50%-60% likelihood of radical surgery. However, she assured us that she will strive to perform a partial surgery if feasible.

Given my father's high blood pressure and the potential side effects of subsequent chemotherapy for rectal cancer, there is a consideration of the worst-case scenario, which could mean he might need dialysis. I don't want to think about it right now. I believe the medical team will closely monitor and adjust the treatment plan accordingly.
