title: [Evidence-based medicine. Usefulness of isolated cystomanometry for the diagnosis of periurethral detrusor-sphincter dyssynergia in patients with suprasacral lesion].
abstract: OBJECTIVE
  To determine the utility of cystomanometry alone in the diagnosis of periurethral detrusor-sphincter dyssynergia in patients with suprasacral spinal cord lesion.
  
  
  METHODS
  Cystomanometry and selective electromyography were performed to evaluate the periurethral sphincter of 40 patients (16 female and 24 male; mean age 46.6 years) with suprasacral spinal cord injury diagnosed by neurological evaluation.
  
  
  RESULTS
  The pre-test probability of having dyssynergia was 0.45. The post-test probability, with cystomanometrically demonstrated hyperreflexia, was 0.58. The likelihood ratio utilizing cystomanometry alone was 1.69.
  
  
  CONCLUSIONS
  Cystomanometry alone is not useful in the diagnosis of periurethral detrusor-sphincter dyssynergia in patients with suprasacral spinal cord injury. Periurethral electromyography should be used in combination with the foregoing technique.
