Hi Pinky, welcome to the club, that no one wants to join. I had my right kidney removed last year, it was keyhole, so very little pain and hospital stay quite short, full recovery about 12 weeks, give or take. All consequent function test's on my remaining Kidney have been good, it was slow to wake up to the fact that it's partner was missing, but it all soon settled down. I feel totally well and having one Kidney has made no difference to me at all. :) I have blood and scan's / x rays done every six months, had a CT yesterday, I am not overly concerned, my specialist said that I have a low to Moderate risk of developing further Cancer sites, so I am hopeful, only time will tell. You are not alone and I for one , know how you are feeling just now. Hugs and stuff x x
