Using Near Infrared Spectroscopy (NIRS) on the Bladder

Researcher(s): Dr. Lynn Stothers

This study is looking at a device that uses light to determine how the bladder muscle uses oxygen, specifically the researchers want to look at the relationship between bladder pressure that is recorded during bladder function studies (urodynamics) and the oxygen in the bladder muscle.

The aim of this study is to develop safe and non-invasive techniques for studying bladder function without the use of catheters in people with neurological injuries or disorders. Currently, all tests related to the function of the bladder require that a catheter be placed.

Why should you participate in this study?

We hope that the information learned from this study can be used in the future to benefit other men and women with bladder symptoms due to a nervous system problem.

You may be eligible to participate in the study if you:

  • Have an injury or disorder related to nerves, spinal cord, or brain
  • Are aged 19 years or older
  • Require examination and measurement of bladder pressure (urodynamics evaluation).

You may be ineligible to participate in the study if you:

  • Are aged less than 19.

Time commitment: You can expect to spend about 15 minutes during the one-hour time slot assigned for standard urodynamics studies. Our non-invasive research study will be done during the urodynamic test.

This study will take place at ICORD/Blusson Spinal Cord Centre (818 West 10th Avenue, Vancouver).

Compensation for participation: A $50.00 honorarium will be granted to you to account for your time and involvement in the study. If you become ill or physically injured as a result of participation in this study, medical treatment will be provided at no cost to you. The cost of your medical treatment will be paid by your provincial medical plan.
