Ureteroceles vs. pseudoureteroceles in adults. Urographic diagnosis
JR Thornbury, TM Silver and RK Vinson
Simple ureteroceles discovered in adults on excretory urography have long
been regarded as congenital anomalies, usually innocuous.
Pseudoureteroceles are acquired dilatations of the submucosal portion of
the distal ureter that mimic simple ureteroceles. The authors compared 5
pseudoureteroceles and 13 simple ureteroceles and found that the former
were distinguished by asymmetry of the dilated ureteral lumen, moderate to
severe obstruction of the upper tract, and evidence of an acquired cause
such as a calculus or abnormal vesical mucosal pattern. The distinction is
important, since most pseudoureteroceles were related to malignancy
involving the bladder.
