I can only speak to my experience recently. I had my entire right kidney removed on April 27ths and spent five days in the hospital. Mostly because my stomach did not like the surgery. You will likely be in the hospital 2-4 days maximum. They will likely advise you not to lift anything for a while. Because they had to remove my kidney, my scar is much larger than the partial. They did not want me to lift anything for about six weeks. They pain for me was very manageable. I stopped using pain meds on my third day and have not had to use them since then. I returned to work 2 1/2 months after surgery. I work a very physical job and needed to be 100% before they (my employer) would allow me back to work.
Hope this helps. I had the same questions.
