Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults aged 18 and older with spinal cord injuries lasting at least six months who manage their bladder through intermittent catheterization.
✕Probably not a fit
Patients with additional genitourinary pathologies, those using prophylactic antibiotics, or individuals with active cancer or autoimmune disorders may not benefit from this study.

What this trial studies
This clinical trial aims to evaluate the effectiveness of Lactobacillus Rhamnosus GG (LGG) combined with saline bladder wash compared to saline bladder wash alone in preventing urinary tract infections (UTIs) among individuals with spinal cord injuries and neurogenic bladder. The study focuses on self-management strategies for participants who experience specific urinary symptoms, such as cloudiness or foul odor. By addressing the diagnostic challenges associated with UTIs in this population, the trial seeks to provide a novel approach to managing urinary health without relying on antibiotics. Participants will be monitored for changes in bladder and urine quality as primary outcomes.
Why it matters
Potential benefit: If successful, this intervention could significantly reduce the incidence of UTIs in patients with spinal cord injuries, improving their overall health and quality of life.
How similar studies have gone: While this approach is novel in the context of spinal cord injuries, similar studies have shown promise in using probiotics for UTI prevention in other populations.
