Gentamicin Bladder Instillation in Individuals With Spinal Cord Injury Having Chronic Urinary Tract Infections

Participants will undergo daily gentamicin bladder instillations to determine if its use will reduce the rate of symptomatic urinary tract infections (UTIs) as well as the use of oral and intravenous antibiotics in adults with chronic spinal cord injury (SCI) who have recurrent UTIs. Participants are randomized into one of three groups: 1) Gentamicin and saline instillation 2) Saline only instillation 3) Standard of care, no instillation.

Key information

About this study

The purpose of this study is to determine if twice daily bladder flushing with an antibiotic solution will decrease the rate of UTIs and the use of oral medications used to treat UTIs. The occurrence of UTIs in the SCI population is high, with a rate of about 2.5 episodes per year. The inability to effectively empty the bladder increases the risk of UTIs, which are the most common medical complication after SCI. This study will help us understand the effectiveness of a local bladder therapy on preventing UTIs and improving bladder function in individuals with SCI.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • At least 18 years of age;
  • Non-progressive spinal cord injury;
  • Stable medical condition;
  • Bladder dysfunction as a result of spinal cord injury
  • History of recurrent UTIs (defined as 3 or more within the past year or 2 or more within the past 6 months).

Exclusion criteria

  • Signs or symptoms of serious UTI that requires the use of systemic antibiotics;
  • Use of any urine-acidifying agent, bladder irrigant, or systemic antibiotic within the previous 2 weeks;
  • Participants colonized with gentamicin-resistant bacteria on baseline urine culture or a gentamicin allergy/sensitivity;
  • Participants with known hearing loss and/or renal disease;
  • Pregnant at the time of enrollment or planning to become pregnant during the time course of the study.

Treatment and study plan

Gentamicin Sulfate

Drug

Gentamicin will be compounded for immediate use in single-dose, disposable BD 50ml Luer-Lok tip syringes. The container closure system for the diluted gentamicin sulfate solution and saline solution will be sterile and processed with depyrogenation. The solution will be slowly infused into the bladder after drainage of urine is complete. While monitoring blood pressure, the solution will remain in the participant's bladder for a least 30 minutes (unless the participant is experiencing autonomic dysreflexia, and in that case, immediately drained) with the goal of attaining 2 hours.

Other names: Gentamicin only

Placebo instillation (saline alone)

Other

Saline will be compounded for immediate use in single-dose, disposable BD 50ml Luer-Lok tip syringes. The container closure system for the diluted gentamicin sulfate solution and saline solution will be sterile and processed with depyrogenation. The solution will be slowly infused into the bladder after drainage of urine is complete. While monitoring blood pressure, the solution will remain in the participant's bladder for a least 30 minutes (unless the participant is experiencing autonomic dysreflexia, and in that case, immediately drained) with the goal of attaining 2 hours.

Other names: Saline only

No instillation

Other

Participants will not receive an instillation of gentamicin or saline alone, but instead will continue standard of care. Participants will be assessed at the pre-, mid- and post-intervention time points.

Primary outcomes

  1. Evaluate Bladder Storage Using Urodynamics

    Time frame: 1. Baseline (1 week) 2. Midpoint (2 months) 3. Post (4 months)

    Assessment of Lower Urinary Tract Function: Urodynamic Bladder Compliance (mL/cm H20) based on Change in Bladder Capacity.

Secondary outcomes

  1. Participants With Symptomatic Urinary Tract Infection

    Time frame: 1. Baseline (1 week) 2. Midpoint (2 months) 3. Post (4 months)

    number of participants with symptomatic urinary tract infection measured by the presence of Leukocyte Esterase level in urine.
