Various growth patterns have been described, including predominantly pedunculated urogrsphy intraluminal growth and sessile with mural invasion.

After intravenous contrast injection, clots do not enhance, whereas urothelial tumors usually do. Case Primary megaureter.

The bowel anastomosis may leak, or a postoperative ileus or bowel obstruction may occur. 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.

Set up My libraries How do I set up “My libraries”? Experience with patients who have undergone cystectomy with urinary diversion, most often for treatment of bladder carcinoma,continues to increase, and CTU is commonly used for surveillance of the urothelium in at-risk patients. The ability to biopsy and resect lesions are added benefits of cystoscopy.

Diseases of the urinary bladder CT urography is useful in detecting and characterizing multiple bladder abnormalities.

Prior to contrast administration, clots will be of soft tissue attenuation. Noninvasive papillary transitional cell. Hematuria following traumatic injury may be an initial clinical clue.

CT urography: Review of technique and spectrum of diseases

Small outpouchings sn the calyx are identified as contrast collections contiguous with a calyx Figure 3. Papillary necrosis is associated with analgesic overuse, sickle cell anemia, diabetes, pyelonephritis, renal obstruction, and renal vein thrombosis. Lesions frequently demonstrate enhancement in the nephrographic phase and appear as filling defects Figure 9 or as an irregular luminal contour in the excretory phase.

The cysts appear as multiple smooth filling defects most commonly in the proximal one-third of the ureter and are often seen in association with chronic urinary tract infections or stones. Urography — methods — Atlases. Caliceal diverticula are incidental findings of little or no significance. Fibroepithelial polyps are benign mesodermal tumors of the ureter composed of a fibrovascular core lined by normal urothelium.

Tomography, X-Ray Computed — Atlases. Not only do these postprocessing techniques allow the radiologist to interact with the data to more fully appreciate pathologic changes, but they also aid in communicating findings to referring physicians. Renal tubular ectasia is characterized by noncalcified cystic dilatation of the collecting tubules. Currently, CT urographic evaluation of the urinary bladder generally is not considered accurate enough to exclude small superficial urothelial tumors, and cystoscopy is indicated for complete bladder evaluation.


As an alternative to the triphasic single bolus CTU technique, the split contrast bolus technique has been designed whereby the contrast is given as 2 boluses before a single enhanced-scan is acquired.

Invasion into the perivesical fat may be revealed as infiltration or irregular fat-bladder wall interface. Accumulating data, however, indicates that CTU is reliable in detecting bladder cancer. Notes Includes bibliographical references and index. One study reported a mean effective dose estimate of We were unable to find zn edition in any bookshop we are able to search.

The large number of very thin section images allows for isotropic presentation of the axially acquired data set in any chosen plane. Mixed type injuries also need to be correctly identified. Ureteral pseudodiverticulosis Figure 4 is associated with chronic inflammation and urothelial neoplasms. Vt urography is useful in detecting and characterizing multiple bladder abnormalities. Conditions commonly referred for CTU include urinary calculus disease, hematuria, flank and abdominal pain, urograpny renal or urothelial neoplasm, a variety of inflammatory conditions, and congenital anomalies of the kidneys and ureters.
