Ureterolith with hydronephrosis in a 15 year old FS DSH cat

Case Study

Ureterolith with hydronephrosis in a 15 year old FS DSH cat

A 15-year-old SF DSH was presented for evaluation of abdominal pain. 

A 15-year-old SF DSH was presented for evaluation of abdominal pain. 

Sonographic Differential Diagnosis

Right ureteral calculus obstruction with chronic hydronephrosis and likely pyelonephritis right kidney. Minor degenerative changes left kidney.

Image Interpretation

The left kidney, measuring 3.9 cm, demonstrated a blunted caudal pole likely owing to infarct or remodeling. The right kidney was small (approximately 2 cm) likely owing to chronic hydronephrosis. Right renal hydronephrosis was moderate with echogenic debris suspect for purulent debris or infectious material. Minimal integrity was noted with the residual cortex of the right kidney. Pericapsular inflammatory pattern was also noted. The right ureter revealed a 0.36 cm calculus with obstruction and measured approximately 0.5 cm.

DX

Ureterolith with hydronephrosis

Outcome

None

Comments

Right nephrectomy and ureterectomy would be a reasonable approach. However, referral for interventional radiology plus or minus intravenous pyelogram (IVP) is an option. Long-term viability of the right kidney is significantly in question.

Clinical Differential Diagnosis

Peritonitis, pancreatitis, ureterolith, trauma, splenomegaly, hepatomegaly, hydronephrosis.

Sampling

None
