title: Persistent primary enuresis: a urodynamic assessment.
abstract: Videocystourethrography with synchronous pressure and flow-rate recordings has been carried out on 50 patients referred for the investigation of persistent primary enuresis. Urodynamic studies showed nocturnal enuresis to be associated mainly with normal detrusor function and nocturnal plus diurnal enuresis mainly with abnormal detrusor function. Evidence is presented which suggests that these two distinct types of enuresis occur de novo and do not overlap. Out of 18 of formerly enuretic male patients nine with abnormal detrusor function showed persistent nocturnal plus diurnal symptoms.
