- 10 year old FN DSH presented for lameness with kidney abnormalities identified incidentally
- High WBC, neutrophilia on bloods and SDMA, urine sg 1.060, culture pending
- Left kidney is completely hydronephrotic with a stone in ureter (and bladder) causing obstruction but there was a severe steatitis with free fluid in the retroperitoneal space. The right kidney was hypertrophied with a stone and medullary markings (how do you describe this again?). There was a mild lymphadenopathy of mesenteric LNs.

- Do you think the steatitis is from infection of the left hydronephrotic kidney? This kidney will need removal but I want to make sure I am not missing other pathology.

The perinephric steatitis
The perinephric steatitis and effusion around the hydronephrotic LK is consistent with chronic inflammation and possible / likely infection associated with the LK with the WBC count. This looks like it probably been going on for a while. I dont see any other obvious pathology.
The RK is likely hypertrophied due to the chronic nonfunctionality of the LK. I dont see signs of RK perinephric inflammation or effusion, or subcapsular effusion or pelvis dilation. There is a mild medullary rim sign in the RK but this is a nonspecific finding. I would suggest checking calcium levels if not recently done.
