The Department of Urology at the Institut Mutualiste Montsouris is a world leader in its field. It has an innovative and unique organisational structure with a specific surgeon plus a medical doctor assigned to individual patients. The department uses pioneering technology like robotic laparoscopy and focal therapy. They have developed a new device, Focal One, to perform a focal therapy of prostate cancer with fusion imaging from Ultrasound and MRI. 12 years ago, the department set up a not-for-profit training school for surgeons in the heart of Paris. The European School of Surgery is located at Descartes University and trains surgeons and medical doctors in these new technologies.
