UrologyMedicine and Medical Science

M.D., Ph.D. Professor Takashi Kobayashi

We have been dedicated to the development of novel treatment strategies and technologies in the fields of malignant diseases (prostatic cancer, renal cancer, urinary epithelial cancer, testicular cancer, etc.), kidney transplantation, and minimally invasive surgeries.
Through the close collaboration with our high-volume clinical department and basic research department, we conduct both translational researches on clinically unmet needs and biological researches on fundamental life science. in a well-balanced manner. We believe that this approach enables us to develop highly trained urological professionals who harbor the scientific and academic perspectives, which are essential abilities for Surgeon-scientists.

Research and Education

About 15 graduate students are engaged in our research laboratory at the Department of Urology, Kyoto University Graduate School of Medicine. Our research themes cover a wide range of topics such as uro-oncology, kidney transplantation, surgical techniques, and physiology of the urinary tract. We have been trying to elucidate the clinical questions and molecular mechanisms in these research fields using novel technologies such as next-generation sequencing, cell analysis, mouse models, and computer science. One of our strengths is that we have abundant clinical specimens (blood, urine, tumor tissue, etc.) obtained with the cooperation of patients at University Hospital and affiliated hospitals. Particularly, research using patient-derived xenograft (PDX) is one of the world’s leading fields in our department with a number of publications of original research and review articles. Although we are aware that research does not always work as we expected and can sometimes be painful, we are engaged in daily research with the motto of sharing the joy of revealing formerly unpreceded problems by original ingenuity.
