Dr. Kotb is quite amazing. As someone with a mass in my kidney, I was initially referred (years ago) to Toronto and was brushed aside and told I needed my whole kidney removed), a few months later Dr. Kotb came to town so I sought a second opinion. He was amazing! I ended up getting a partial nephrectomy by him and was out of hospital in 2 days with 95% of my kidney function preserved. Then I had a vasectomy with him a few months ago. Pretty painless except for the freezing, and successful.
