Study Summary

This trial compares a new self-management intervention to prevent UTI to usual care.

Who is the study for?
This trial is for adults over 18 with spinal cord injury (SCI) for at least 6 months, who manage their bladder using intermittent catheterization and live outside of acute care settings. It's not open to those with other genitourinary issues, current antibiotic use, recent intravesical treatments or oral antibiotics, immune deficiencies, certain psychological conditions, participation in conflicting studies, recent LGG® exposure or active cancer/autoimmune diseases.Check my eligibility
What is being tested?
The study tests a new way to prevent urinary tract infections without antibiotics in people with neurogenic bladders due to SCI. Participants will either receive an innovative treatment called Lactobacillus Rhamnosus GG directly into the bladder or a standard saline wash as a comparison.See study design
What are the potential side effects?
Potential side effects may include discomfort during the bladder instillation process and possible mild urinary symptoms related to the introduction of substances into the bladder. However, since this is an antibiotic-sparing approach using probiotics or saline washes, severe side effects are less likely.

4Treatment groups
Experimental Treatment
Group I: Intravesical Lactobacillus RhamnosusGG and Bladder Wash (Treatment Phase)Experimental Treatment1 Intervention
LGG® (Culturelle Probiotic LGG®) will be used. This is the product we have used in the past and for which we have demonstrated safety, tolerability, and preliminary efficacy. For the LGG® instillation in response to trigger symptoms, participants will be instructed to mix the contents of 1 LGG® capsule into 45 cc sterile 0.9% saline. After mixing, participants will draw up the 45cc liquid LGG® mixture into a 60cc syringe and instill via the intermittent catheter after the last catheterization prior to going to bed. Participants will be asked to return any remaining capsules at the end of the study. Participants will be instructed to complete the USQNB-IC at the time of symptoms (in real time) and daily during instillations for 2 days after the final instillation. Subjects will remain in this phase 6 months.
Group II: Intravesical Lactobacillus RhamnosusGG and Bladder Wash (Prophylaxis Phase)Experimental Treatment1 Intervention
LGG® (Culturelle Probiotic LGG®) will be used. This is the product we have used in the past and for which we have demonstrated safety, tolerability, and preliminary efficacy. For the LGG® instillation in response to trigger symptoms, participants will be instructed to mix the contents of 1 LGG® capsule into 45 cc sterile 0.9% saline. After mixing, participants will draw up the 45cc liquid LGG® mixture into a 60cc syringe and instill via the intermittent catheter after the last catheterization prior to going to bed. They will then instill the LGG® mixture every 2 days for the remainder of the 6 months. Participants will be asked to return any remaining capsules at the end of the study. Participants will be instructed to complete the USQNB-IC at the time of symptoms (in real time) and biweekly post-instillation. Subjects will remain in this phase 6 months.
Group III: Intravesical Bladder Wash (Treatment Phase)Experimental Treatment1 Intervention
Participants will draw up the 45cc of normal saline into a 60cc syringe and instill via the intermittent catheter after the last catheterization prior to going to bed after trigger symptoms occur. Participants will be instructed to complete the USQNB-IC at the time of symptoms (in real time) and daily during instillations for 2 days after the final instillation. Subjects will remain in this phase 6 months.
Group IV: Intravesical Bladder Wash (Prophylaxis Phase)Experimental Treatment1 Intervention
Participants will draw up the 45cc of normal saline into a 60cc syringe and instill via the intermittent catheter after the last catheterization prior to going to bed after trigger symptoms occur. They will then instill the saline BW every 2 days for the remainder of the 6 months. Participants will be instructed to complete the USQNB-IC at the time of symptoms (in real time) and biweekly post-instillation. Subjects will remain in this phase 6 months.
