title: The primary megacystis syndrome.
abstract: We discuss 7 cases of the primary megacystis syndrome to demonstrate that the syndrome is non-obstructive and non-neurogenic, and probably of psychogenic origin owing to learned dysfunctional voiding. The major complication is vesicoureteral reflux and initial therapy is aimed at its correction. Prolonged followup and retraining of voiding habits are necessary. Specific pharmacologic or biofeedback techniques are indicated should urodynamic abnormalities of function be evident.
