title: Negative cystography with bladder rupture: presentation of 2 cases and review of the literature.
abstract: Cystography is commonly thought to be the sine qua non in the diagnosis of perforation or rupture of the bladder. Recently, we encountered 2 cases of bladder rupture discovered at subsequent exploration in which preoperative cystography had been negative. The reasons for these negative radiographic findings in light of a non-intact bladder are discussed and a technique for cystography is suggested that will reveal disruptions of the bladder with greater certainty.
