Management of polycystic kidney disease by ultrasound-guided percutaneous aspiration in a cat

A 5-year-old female Persian cat was presented with the owner?s complaint about lethargy, anorexia, and no defecation. Physical examination revealed relatively poor general health status. Also, marked azotemia was one of the prominent findings of clinical pathology. Abdominal ultrasound revealed smooth-walled anechoic cysts in both kidneys, characteristic of feline polycystic kidney disease. Three weeks after the initiation of supportive therapy, percutaneous aspiration of large cysts was performed under the guidance of ultrasonography. The contents of the cysts were hypocellular and did not contain infectious or neoplastic cells. Following the re-examination of the patient after 30 days, the clinical and hematological parameters were notably improved. Therefore, aspiration of cysts guided by ultrasonography can be beneficial in alleviating some of the complications of polycystic kidney disease and improving the life quality of affected cats. However, it may be temporary, and this method needs to be repeated periodically.
