I only needed a ride home after the Robot surgery and an over night at the hospital and Uber or a neighbor could have done that. I handled the catheter and bag and stairs at home and driving to the doctor to remove the catheter and driving home after removal and I handled getting my own food from the microwave. So that was my experience, if that is any guidance. That said, it would be wise to hire a back up caregiver in case there is a complication and staying another day in the hospital after the Robot surgery might be good.
Also, a three month delay MIGHT not hurt as this is a slow growing cancer, yet it is it is still a cancer. My doctors delayed my surgery 6 months and put me on ADT 6 months before surgery as they advised me that the ADT softens up the cancer and gives them a better chance to remove it all. Good luck
