Obstructive ureteral calculus and pelvic calculus with hydroureter in a 5 year old FS Miniature Schnauzer

The urinary bladder presented a minor amount of suspended debris, dependent debriswithout acoustic shadowing. The ureteral jets were normal with normal urine flow.

The left kidney presented slight, comet tail infarct with corticomedullary calculi that were small enough to pass. The patient is likely passing calculi periodically from this kidney. The right kidney presented pelvic calculus and dilated ureter. Swollen irregular contour and loss of corticomedullary definition. A 1.0 cm right pelvic calculus was noted with multiple other corticomedullary calculi and hydroureter expanding to hydronephrosis measuring 2.0 x 1.5 cm. The right ureter continued caudally measuring approximately 0.8 cm with an obstructive calculus that measured approximately 2.0 cm mcaudal from the right renal pelvis. The right ureteral calculus measured approximately 1.0 cm, which is too large to pass on its own.

The gallbladder presented minor polypoid changes and minor over distension. The gallbladder revealed a double layered wall.
