Urology

Last updated on 2022-09-07

Over the years NIRS has been utilized in many different fields of research. Recently, NIRS has also found use in the field of urology. Indications show that bladder blood flow and oxygenation differ in health and disease. NIRS can non-invasively monitor changes in oxyhemoglobin and deoxyhemoglobin in the bladder, providing physiological information not available by other means.
