Prevention of urinary tract infection in patients with spinal cord injury--a microbiological review.

Abstract

The importance of urinary tract infection (UTI) in patients with spinal cord injury cannot be understated. Many patients with significant bacteriuria are considered to be colonised rather than infected, and treatment should be reserved for those with clinical symptoms or other signs of infection. Published research on the prevention and management of UTI in patients with spinal cord injury often has limitations due to differences in definitions of UTI, studies on groups using different urinary drainage appliances, the mixture of newly injured and longstanding injured patients and studies being carried out predominantly on male patients. The complications due to UTI and the difficulties in treating established infection mean that prevention is essential. Close urological follow-up is crucial in ensuring that adequate bladder drainage is achieved avoiding the use of long term indwelling urinary catheters if at all possible. For those patients who require long term urinary appliances patient education and strict attention to hygiene and catheter care policies is important. The role of antiseptic/ antibiotics is strictly limited in preventing UTI in patients with spinal cord injury and may even be harmful. Further study into which groups of patients may benefit from the use of antiseptics or antibiotics is urgently required. Continued research into different methods of prevention eg by vaccination, immunotherapy, the use of receptor analogues and bladder interference should also be encouraged.
