Urology and Andrology

Anesthesiology and Pain Relief Center

The Department of Urology and Andrology specializes in diseases of the urinary tract and male genital organs, such as adrenal gland, kidney, ureter, bladder, prostate gland, testis, urethra, and penis.

Medical services

Approximately 20 urologists work together to provide daily care in the outpatient clinic and the inpatient ward. The outpatient clinic is open from Monday to Friday to provide general medical services, specialized outpatient services and urologic examinations. There are 17 specialized outpatient clinics handling consultations and treatment for different types of tumors, lower urinary tract symptoms and intractable disease.

Diagnosis and treatment policy

With a patient-oriented approach, an individualized treatment plans are developed at department conferences and treatment is provided based on a team approach.


The department specializes in the treatment of prostate cancer and other malignant tumors (tumors of the kidney, renal pelvis, ureter, bladder, prostate and testis). We also provide chemotherapy. Medical care for patients with adrenal tumor, lower urinary tract symptoms, interstitial cystitis, urinary incontinence, pelvic organ prolapse, urolithiasis, late-onset hypogonadism renal transplantation, and hemodialysis are also provided.
