Department of Urology

Message from the Director of the Department

The Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences makes progressive approaches in all fields of urology and aims to provide optimal care by standing in the patients’ shoes and by respecting the key principles of “progress, dialogue and kindness.” Not only general outpatient services of urinary tract stones, tumors, infectious diseases and urological impairment but also specialized outpatient services of female urology, neurogenic bladder, urinary incontinence, male infertility and internal secretion, male sexual dysfunction, prostatic gland, tumors, infectious diseases, and urostoma are provided. Using a patient-friendly approach, this general diagnosis and treatment department works on a wide range of urinary diseases, from a combination of less-invasive and effective examination, surgical therapy including robotic surgery, medical therapy with drugs, and holistic medical care providing psychological support.
