Psychogenic voiding patterns.

A urodynamic analysis was performed on 1,300 patients to precise typical psychogenic voiding patterns. Only 2.7% of this selected group showed voiding alterations derived from a psychosis or neurosis. The psychosomatic voiding alterations were to some degree similar to the alterations which were provoked by exogenous or iatrogenic influences. The voiding pattern of young children differs from that of adults when comparing psychosomatic symptoms such as prostatitis or enuresis. Urine retention and megalocystis were characteristic findings of psychotic patients whereas a polyphasic flow pattern, a delay of micturition and increased sacral reflex activity were typical findings of psychosomatic disorders. The denervation supersensitivity test is a reliable test to differentiate neurogenic from psychogenic voiding patterns.
