Abstract
An apparatus for monitoring an analyte comprises a urethral catheter (1), which has positioning means (13) for positioning the catheter within the urethra, and a sensor (19). In use the sensor (19) is held in close proximity to a urethral wall U, permitting monitoring of the analyte level in the urethral wall thereby providing information which may be useful in evaluation of the vita conditions of a patient.
