CT Evaluation of the Rupture of the Proximal Collecting System by Distal Ureteral Microlithiasis-Literature Review and Case Report

Ureteral rupture is a potentially dangerous event, the diagnosis of which is often delayed because of its rarity. Spontaneous ureteral rupture is a rare condition and ureteral calculi are the most frequent causes. In some cases, the cause is unknown. The diagnosis is made by computed tomography, the non-contrast phase shows the stone in the ureter and the excretory phase shows contrast extravasation, confirming the rupture. Management of the spontaneous ureteral rupture is not standardized because few systemic reports are available now. The conduct with minimally invasive procedures or conservative treatment yields the best results.
