School ager with incontinence

CT of spinning top urethra
Coronal MIP simulating an intravenous pyelogram (above left), coronal (above right) and axial (below) CT urogram with contrast shows the right kidney to be duplicated. There were normal ureteral insertions bilaterally into the bladder (not pictured). There was an oval structure inferior to the bladder that appeared to be the posterior urethra.

The diagnosis was spinning top urethra in a patient with a right duplicated kidney.
