The specific objective of this clinical trial is to demonstrate that a multifaceted approach for treatment for catheter-related urinary tract infection (UTI) in patients with spinal cord injury is effective and feasible. We plan to test the following hypothesis: a multifaceted treatment approach that consists of immediate removal of the indwelling bladder catheter, selecting antibiotics based on the finding from a urine culture that is obtained through the newly inserted catheter, and a 5-day course of systemic antibiotics will effectively treat catheter-related infection that is limited to the lower urinary tract of patients with spinal cord injury.
