title: Bladder function in healthy volunteers: ambulatory monitoring and conventional urodynamic studies.
abstract: OBJECTIVE
  To obtain data on conventional artificial filling cystometry and ambulatory monitoring in healthy asymptomatic control populations.
  
  
  METHODS
  Seventeen healthy volunteers were assessed by means of artificial filling cystometry (CMG), filling at rates of 50 ml/min (CMG 50) and 100 ml/min (CMG 100), and ambulatory monitoring (AM).
  
  
  RESULTS
  Significant differences were found between AM and CMG with respect to: the pressure rise on filling (P < 0.02), voided volumes (P < 0.01) and maximum detrusor pressure on micturition (P < 0.01). Detrusor instability was found in 38% of volunteers on AM, in 17% on CMG 50, but in none on CMG 100.
  
  
  CONCLUSIONS
  A range of baseline urodynamic values has been established which could provide the basis for future studies of ambulatory monitoring.
