DX

Dorsal bladder mass encroaching upon the right ureteral papilla with early obstruction.

Outcome

Ureteral stent placement may be the best option with chemoreduction or surgical reduction of the bladder
mass. Neither kidney revealed pyelectasia at the time of imaging. There was suspicion of developing pyelectasia of the right kidney over time. Invasion of the right ureter appeared to be present in the last 1.0 cm of the ureter.
A guarded to poor long term prognosis was given.

Image Interpretation

The urinary bladder revealed a dorsal wall mass that measured 3.0 cm. The mass was moderately vascular. The right ureter was slightly dilated at 0.28 cm. The pelvic urethra was imaged 3.0 cm beyond the cystourethral junction. There were slight wall irregularities noted at the ureteral papilla. The urethra appeared to be free of evident pathology as did the cystourethral junction. The mass presented intramural encroachment on the right ureteral papilla causing secondary dilation and rendering this mass non-resectable unless ureteral transposition is to be performed given the early obstruction.
