Clinical and Urodynamic Assessment of Bladder Sensation in Multiple Sclerosis

This study is examining how multiple sclerosis (MS) affects the bladder — specifically, how the brain and nervous system control the sensation of needing to urinate. People with MS often experience bladder problems, and this research uses urodynamic testing (a procedure that measures bladder pressure and function) to understand the underlying mechanisms. **You may be eligible if...** - You are 18 or older with a confirmed MS diagnosis - You have bladder problems that are thought to be related to your MS - You have been referred for urodynamic testing - You are not currently taking bladder medications - You can read and communicate in French and have French social security coverage **You may NOT be eligible if...** - You are pregnant or breastfeeding - You had an MS relapse in the past month - You have another neurological condition - You are already taking medications for bladder issues Talk to your doctor to see if this trial is right for you.
