I had a partial done with the DaVinci machine last Thursday where they removed 50 percent of my right kidney. I will go back 2 days from now so they can determine if the remaining half will survive because the blood supply is now limited. I've been reading a lot of you're posts and signed up because they are a lot more informative than anything else I've seen. Plus I have a lot of time on my hands now as you can imagine. I discovered the mass back in late January while they were looking for kidney stones. They want to try and preserve as much of the right kidney as possible because of my age and the fact that I have what they describe as cysts on the left which they are not as concerned with yet. I am a 43 year old male father of 2. Best of luck to everyone out there! Thanks!
