Brief Summary:
A cross over study evaluating the efficacy of intravesical gentamicin on the occurrence rate of urinary tract infections and bladder complications in patients after spinal cord injury (SCI), and to assess its effectiveness in promoting overall quality of life (QOL), community living, and participation.

Resource links provided by the National Library of Medicine

Arm Intervention/treatment
Experimental: Gentamicin sulfate Drug: Gentamicin Sulfate
Gentamicin will be compounded by the Michigan Medicine Research Pharmacy in a concentration of 480 milligrams of the active product to 1000 milliliters of normal saline. Participants will do daily instillations of 30 milliliters of solution

Primary Outcome Measures :
  1. Number of urinary tract infections (UTI) [ Time Frame: 6 months ]
    Number of reported urinary tract infections (UTI) by participants

Secondary Outcome Measures :
  1. Change in score of Neurogenic Bladder Symptom Severity scale [ Time Frame: 6 months ]
    Self-reported bladder symptoms on a scale from 0 (no symptoms) to 74 (maximum symptoms)

  2. Change in score of Neurogenic Bowel Dysfunction [ Time Frame: 6 months ]
    Self-reported bowel symptoms on a scale from 0 (very minor) to 14+ (severe)
