Ureteral pseudodiverticulosis

Case contributed by Dr Matt A. Morgan


Microscopic hematuria. The patient recently had a CT urogram in which there was nonfilling of the right distal ureter, so a retrograde pyelogram was ordered.

Patient Data

Age: 65 years
Gender: Male

Images from a retrograde pyelogram: In the mid-ureter, there are tiny (1-2 mm) outpouchings of contrast, compatible with ureteral pseudodiverticulosis.

Case Discussion

Ureteral pseudodiverticulosis is an uncommon process that has been associated with the development of urothelial (transitional) cell carcinoma.

It can be seen on a CT urogram (CTU) but is much easier to detect on IVU or a retrograde pyelogram. In this case, the pseudodiverticula was not visible on the CTU.
