Learning objectives

- to illustrate the differences in appearances ofureteral thickening: mucosal or submucosal thickening - to discuss the different etiologies of ureter thickening correlated with clinical evolution, analytical results and pathology

Background

The clinical presentation of the ureter thickening is highly variable. It may be asymptomatic; alternatively it may cause colicky pain or haematuria or it may present clinical and analytical signs of sepsis. Treatment options vary depending on the aetiology which may be A) inflammatory (pyelitis or pyeloureteritis related or not to kidney stones), B) catheter-related or idiopathic; C) infectious (related to tuberculosis or bacterial infection); or D) neoplastic (related to urothelial carcinoma or lymphoma). Knowledge of the different radiological manifestations of the etiologies of thickening...

Findings and procedure details

The radiological appearances of mucosal o submucosal ureter wall thickening are different, correlated by pathology. The ureteral wall is thin and is composed by mucosa, lamina propria, muscle. (Fig. 1) Usually, mucosal thickening is caused by cell proliferation at the mucosal and lamina propria (Fig. 2). Submucosal thickening is caused by cell proliferation at the lamina propria (Fig. 3). We studied different patients with radiological alterations of the ureter wall on CT and correlated them with the clinical evolution and/or pathology. There are some diseases...

Conclusion

The CT appearances of the ureteral thickening helps to reach the correct diagnosis, helped by clinical and analytical findings.
