An estimated 86,500 people are currently living with spinal cord injury (SCI) in Canada, and approximately 4,300 more will experience SCI each year. In persons with SCI, the bladder can't receive or send the signals required for normal organ function, and 80 percent of persons with SCI are affected by acute or chronic urinary tract complications that negatively influence their health, quality of life and impact their life expectancy. Currently, evaluation of bladder function is limited to periodic urodynamic testing (UDS), an invasive procedure that requires patients to have catheters inserted into the urethra and rectum. Besides being a painful and inconvenient procedure, the invasive nature of this diagnostic method exposes patients to the risk of serious complications such as urinary tract infection, trauma and bleeding that may further complicate urinary tract conditions. Dr. Babak Shadgan is investigating the use of near-infrared spectroscopy (NIRS) as a novel non-invasive diagnostic method to evaluate the physiologic mechanisms underlying bladder dysfunction in people with SCI. Detecting when the bladder has filled to a given volume or size is essential to avoid accidental incontinence and also to prevent damage to the kidneys from backpressure secondary to a full bladder. NIRS is a non-invasive optical technique that uses light to monitor changes in tissue oxygenation and changes in blood supply to the bladder as the organ fills and empties. Using NIRS for bladder monitoring in this population will demonstrate both scientific relevance and commercial potential and will lead to the development of an NIRS device capable of more effective, more comprehensive, and safer evaluation of bladder dysfunction than current methodologies. The health care burden associated with bladder dysfunction secondary to SCI is considerable; hence, the further development of NIRS for monitoring devices and diagnostic techniques for persons with SCI has potential to reduce complications associated with current invasive tests and improve the standards of care in this population.
