After returning to Germany, he was able to gain recognition as a specialist in urology at both national and European levels, and received the title of F.E.B.U. (Fellow of the European Board of Urology). At the largest European center for robot-assisted urology, the St. Antonius Hospital in Gronau, he was able to acquire his long-standing experience and specialization in Da Vinci surgeries.

Born in Germany, Sergey Sarychev spent his formative years in Russia. He completed his medical training in Saint Petersburg, specializing in Urology.

Subsequently, his professional path led him to Switzerland, where he was involved in the development of robotic urology, the bladder and prostate cancer center, and reconstructive robotic urology at the cantonal hospitals in Frauenfeld and Münsterlingen. During this time, he served as the Senior Consultant Urologist and Head of Robotic Urology. After nearly four fulfilling years, he decided to embark on a new path in his career as an independent urologist.
