The importance of urodynamic investigation following spontaneous rupture of the bladder.

We report a case of spontaneous intraperitoneal rupture of the bladder. Followup urodynamic studies revealed unsuspected detrusor bladder neck dyssynergia that was treated by unilateral endoscopic bladder neck incision. The pathogenesis of spontaneous bladder rupture is discussed and we recommend urodynamic evaluation in all cases of spontaneous rupture.
