I thought I would share with you this page about removing part or all of a kidney. You will also find on this section information about what to expect on the day and what happens after kidney surgery.
I have found this thread by [@Taffykins] who mentions having had the kidney and ureter removed in December 2019 so it could be a good person for you to chat to so feel free to respond to their thread.
If you have any questions or would like to talk to one of our cancer nurses about the surgery and recovery, don't hesitate to ring them on this free number 0808 800 4040 - their line is open Monday to Friday from 9am to 5pm.
I hope your surgery goes well and that you make a swift recovery. Let us know if you get a chance how it all goes.
