Case Summary:
A 6-month-old male domestic shorthair cat presenting with abdominal distension and an acute history of renal azotemia was diagnosed with bilateral perinephric pseudocysts and International Renal Interest Society (IRIS) grade 3 acute kidney injury. Ultrasound-guided drainage of the cysts was performed initially; bilateral subtotal resection of the perinephric pseudocysts was later performed using laparoscopy as a more long-term solution. There was no regrowth or reformation of the perinephric pseudocysts 1 year after the procedure, and the cat remained in IRIS stage 2 chronic kidney disease 1 year postoperatively.
Relevance And Novel Information:
Compared with traditional surgical approaches, laparoscopic resection of perinephric pseudocysts provides a less invasive approach. Bilateral perinephric pseudocyst in a pediatric feline patient (and associated treatment) has not previously been documented in the literature.
