Dr. Sandeep Gupta is a very experienced and respected Urological surgeon in Kolkata.. A couple of months back, I was diagnosed with malignant Renal Carcinoma (Kidney tumor- cancer), and I needed an urgent full Radical Nephrectomy (whole left kidney to be removed).. He operated on me at Columbia Asia hospital.. It was a mammoth surgery, as my kidney had critical anatomy and so it took 6 hours.. But it was worth it.. Dr. Gupta executed the surgery so good that – it became the 1ST FULL LAPROSCOPIC Nephrectomy operation in that hospital\’s history.. Yes, he did it full lap, and since it was not open surgery, my recovery had been extremely good.. He was very helpful and provided great guidance throughout the pre and post surgery visits as well… I can not thank Dr. Gupta enough.
