    Abstract:
    Even though the mortality due to urinary tract complications has decreased dramatically during the last decades in individuals with spinal cord lesions (SCL), urinary tract infections (UTI) still cause significant morbidity in this population. Complicated UTI are caused by a much wider variety of organisms in individuals with SCL than in the general population and are often polymicrobial. Escherichia coli, Pseudomonas spp., Klebsiella spp., Proteus spp., Serratia spp., Providencia spp., enterococci, and staphylococci are the most frequently isolated bacteria in urine specimens taken from individuals with SCL. There is no doubt that the greatest risk for complicated UTI in these individuals is the use of an indwelling catheter. Intermittent catheterisation during the rehabilitation phase has been shown to lower the rate of UTI, and virtually eliminate many of the complications associated with indwelling catheters. Persons with SCL should only be treated for bacteriuria if they have symptoms. Generally, it is advisable to use antibacterial agents with little or no impact on the normal flora. Single agent therapy - in accordance with antimicrobial susceptibility test - is preferred. We advise extending treatment to at least 5 days, and in those with reinfection or relapsing UTI, at least 7 to 14 days, depending on the severity of the infection. The diagnosis of structural and/or functional risk factors is essential in order to plan an optimal treatment for UTI in individuals with SCL, which should include treatment of simultaneously occurring predisposing factors. The treatment of structural risk factors follows general urological principles, aiming for sufficient outlet from the bladder with minimal residual urine and low pressure voiding. For prevention of UTI, general cleanliness and local hygiene should be encouraged. If the patient has a reinfection or relapsing symptomatic UTI, it is important to check for inadequately treated infection and complications, which need special attention, in particular residual urine and urinary stones. No reliable evidence exists of the effectiveness of cranberry juice and other cranberry products. Prophylactic antibacterials should only be used in patients with recurrent UTI where no underlying cause can be found and managed, and in particular if the upper urinary tract is dilated. Antibacterials should not be used for the prevention of UTI in individuals with SCL and indwelling catheters. However, the use of prophylactic antibacterials for individuals with SCL using intermittent catheterisation or other methods of bladder emptying is controversial.
