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.
