Micturition monitor as an aid to management of neurogenic bladder.

A portable, battery-operated micturition monitor has been developed for use by patients with spinal cord injuries. The monitor, when integrated into the external urinary collection device for a male with a spinal cord injury, provides an accurate measure of the elapsed time in minutes since the patient last voided. This measure greatly reduces the efforts required by the medical staff to obtain a reliable residual urine volume measurement.
