Multiple small contrast-containing outpouchings are evident on excretory images.

These diversions may be imaged on CTU.

Ureteral strictures may be the result of prior surgery or instrumentation, stone passage, primary urothelial neoplasms, penetrating injuries, prior radiation therapy, ischemia, retroperitoneal fibrosis, endometriosis, metastatic tumor encasement, or an infectious disease e.

Often, stones are found at or near the ureterovesical junction, and it may be necessary to differentiate a stone lodged in the distal ureter from one that has passed into the bladder lumen and which is lying on the dependent wall.

Technique Most CTU protocols are triphasic examinations that include noncontrast, enhanced, and delayed images. After intravenous contrast injection, clots do not enhance, atlaz urothelial tumors usually do.

CT urography is well suited to detect such complications. Then set up a personal list of libraries from your profile page by clicking on your user name at the top right of any screen.

While diagnostic unenhanced and nephrographic acquisitions are relatively easy to obtain, optimal opacification and distention of the ureters during the excretory phase can be more problematic.

A variety of techniques have been proposed to improve visualization, including oral and IV hydration, diuretic administration, use of a compression belt, prone positioning, and a log-rolling prior to the excretory acquisition. What is the current role of CT urography and MR urography in the evaluation of the urinary tract?
