Role of detrusor instability in primary enuresis.
We studied 50 enuretic boys and girls by supine cystometry. Detrusor instability was found in 74 percent of the cases. The mean threshold volume at which detrusor instability was demonstrated was 200 mL. The mean bladder capacity of age-matched nonenuretic children was 325 mL. We consider detrusor instability at this reduced threshold volume to be the main cause of primary enuresis.
