Experimental stress and cystomanometric recordings of patients with primary enuresis, a preliminary report.

The motility of the bladder has been recorded for 20 children with nocturnal enuresis while they were submitted to emotional tenseness experimentally induced. The analysis showed that emotional stress leads to contractions of the detrusor only in patients with psychogenic enuresis and not in those for whom organic lesions were responsible for the disturbance and that the motor response depends on the level of emotional tenseness. Such results are of interest for diagnosis and physiopathology of psychogenic enuresis.
