Many thanks to the director of the center Prof. Khatkov Igor Evgenievich for the laparoscopic surgery performed on me on 04/21/2022! He is an unsurpassed specialist in his field, which is recognized by his fellow doctors in many other medical institutions in Moscow. I had my tumor removed and my kidney preserved, which was very important to me. Many thanks also to the head. Department of Pelvic Floor Oncosurgery, Ph.D.Valiev R.K. and my attending physicianM.N. Saryev, who assisted during the operation. I am glad that I have fallen into the safe hands of such doctors.
