I was a patient of Dr. Victor Corona for several years, after a ureteral injury occurred in another intervention by another surgeon. The problem was delicate due to the configuration of the damage. Dr. Corona, with great diligence and kindness, took me in charge and performed a high-tech ureteral reimplantation surgery that was so successful that today, four years after the intervention, I have no consequences of that problem. I was very impressed by the quality and professionalism of the critical and very human help that Dr. Corona offered me in this very difficult moment of my life
