robotic partial nephrectomy in my future

ct scan says i have a 3.4 mass on right kidney probably RCC. No biopsy was done. kidney function is good. they found it by accident looking for kidney stone in the ER. That pain was stupid nasty! The dr. says it's a piece of cake to take it out. I'd love to hear from you guys what i can really expect. How long will i be in the hospital? how long does it take to recover? Is there alot of pain involved? what should i look out for? I'm having a bad month, diagnosed with PC also. That biopsy was no fun either lol. If it is malignant is there post op. therapy or scans involved? Will appreciate anything you can share thanks
