MR urography findings of a duplicated ectopic ureter in an adult man.

Abstract

In this report we present the imaging findings in an adult male with a duplicated ectopic ureter which inserted into the prostatic urethra. The appearances at excretory urography, US, CT, and MR urography are described together with the potential pitfalls of the imaging techniques. Both US and MR urography accurately image the collecting system from the kidney to the point of distal ureteral insertion, and in our patient, MR urography provided similar information to US.
