Role of Residual Urine and Asymptomatic Prostatitis in the Development of Urinary Tract Infections in Spinal Cord Injury
Role of Residual Urine and Asymptomatic Prostatitis in the Development of Urinary Tract Infections in Spinal Cord Injury
The purpose of this prospective study is to investigate the association between the amount of
 residual urine and asymptomatic bacterial prostate infection with the occurrence of recurrent
 (>2 /year) symptomatic urinary tract infections in patients suffering from chronic (> 1 year)
 spinal cord injury (SCI) and neurogenic lower urinary tract dysfunction performing
 intermittent catheterization.

 The following hypotheses will be tested:

 1. The amount of residual urine after intermittent catheterization is significantly greater
 in SCI patients suffering from frequent (>2 /year) urinary tract infections compared to
 those without.

 2. The incidence of asymptomatic bacterial prostate infections is significantly higher in
 SCI patients suffering from frequent (>2 /year) urinary tract infections compared to
 those without.
To investigate the association between the amount of residual urine and asymptomatic
 bacterial prostate infection with the occurrence of recurrent (>2 /year) symptomatic urinary
 tract infections in patients suffering from chronic (> 1 year) spinal cord injury (SCI) and
 neurogenic lower urinary tract dysfunction performing intermittent catheterization, patients
 perform self-catheterization twice (before and after urodynamic testing. After each
 catheterization, residual urine is assessed by ultrasound. Prior to urodynamic testing,
 prostate massage is performed, bacterial cultures of the fluid and the urine are initiated
 and the results of these cultures will be analysed .
