Bilateral laparoscopic subtotal perinephric pseudocyst resection in a cat.

A 17-year-old castrated male domestic shorthair cat was diagnosed with bilateral perinephric pseudocysts (PNPs). Bilateral subtotal resection of the PNPs was performed via a laparoscopic approach. There was no regrowth or reformation of the PNPs after the procedure and the cat's serum concentration of creatinine remained stable for 6 months after surgery. Laparoscopic bilateral subtotal resection of PNPs appears to have been an effective treatment option in this cat with the advantages of being minimally invasive and requiring only a brief hospital stay.
