Urodynamic studies in enuresis and the nonneurogenic neurogenic bladder.

We studied urodynamically 55 patients with enuresis. The severity of urinary incontinence ranged from occasional nocturnal episodes to daytime and nighttime wetting associated with radiographic abnormalities of the bladder and upper urinary tract. Despite differences in symptoms, urodynamic findings of poor cerebral appreciation of the degree of bladder filling and sudden unanticipated detrusor contractility were common in 50 of the 55 patients. Volitional detrusor sphincter discoordination also was common and appeared to be related to uncontrolled bladder contractility rather than a primary problem.
