14 yr MN Heeler cross with weight loss over 6 months despite normal appetite, no vomiting or diarrhea. Found this renal cyst on ultrasound. Blood work from earlier in the fall did not show azotemia, repeating today and a UA is also pending. Wondering if you might recommend draining it and if so, any specific precautions besides sedation and how likely it will be to return.
Comments
Generally renal cysts are incidental findings but can cause some degree of pain as there is stretching of the renal capsule. FNA drainage often of short duration as the cyst fills up again but always good to eliminate underlying infection or neoplasia with cytology/culture. Best treatment (if needed) is surgical removal.
Thank you so much!
I usually dont drain unless causing discomfort, has inflammation or echogenic debris and when draining it approach it through cortical parenchyma as opposed to the thin capsule so it doesnt risk leaking
Great – thank you for the additional advice.
