Manny is a 6 1/2 year old male neutered Havanese. Sadly he belongs to my son. I was called over to their home one evening and he was shaking with discomfort. This seemed to pass over the next 24 hours. I brought him in to the clinic and worked him up. His blood work and urinalysis were totally normal. BUN and Creat were both normal. His urine was clean with a SG of 1.049.
X-rays revealed a grossly enlarged R kidney.
I did an ultrasound on him yesterday and all was well except for the kidneys. I am posting a couple of .jpg and 2 cines.

My question- is the large cyst on the R kidney originating from the parenchyma or is it peri-renal. How can you tell?
I tried to drain it with a 22 guage needle and very little came out. This surprised me. Any suggestion on draing this cyst.
How would you medically manage this case?
Large cyst is on the R kidney

The renal capsule encompasses
The renal capsule encompasses the cyst and the cyst is continuous with the renal raprenchyma toward the pelvis weoihtout being separated by the capsule so you know its renal. Perirenal pseudocysts have fluid around nearly the entire renal cortex with the capsule completely or nearly completely detached form the cortex and occurs only in cats. If you have to sample this cyst do it through the cotex and not through the thin capsule. That way you can use the cortex to seal off the needle hole (see attached arrow on image from your video). Or heminephrectoma if it gets infected continually but most of these are best left alone unless you grow bugs out of it.

Thanks EL for the info. I
Thanks EL for the info. I won’t forget.
If this was your dog and he was assymptomatic at this time- would you drain this?

I would drain it once as
I would drain it once as described and culture. If nothing clinical then would leave it alone thereafter.
