Objective:
To obtain data on conventional artificial filling cystometry and ambulatory monitoring in healthy asymptomatic control populations.
Subjects And 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.
Conclusion:
A range of baseline urodynamic values has been established which could provide the basis for future studies of ambulatory monitoring.
