hello and welcome to this case from first opinion veterinary ultrasound I'm Dr Camilla Edwards this was a case of a nine-year-old female neutered English Bull Terrier with a history of hematuria so what we found in this case was when scanning the left hand side where the kidney should be we found this very small kidney-like structure but but very small for what it what it was again here we can see this very small abnormal kidney here Fanning through it um we've got this small kidney possibly some cortex and medulla visible there and it was measuring um at about uh 2.4 centimeters so for an English Bull Terrier that's that's incredibly small for a kidney this it was in comparison to the right hand side where we had a much larger kidney um here we can see the cortex and we've got the medulla clearly and the pelvic area here um much bigger kidney more normal looking kidney kidney here and this was my measuring a more healthy uh 6.7 centimeters I'm Fanning through um this kidney this normal kidney on the right hand side so in this case we had a left kidney that was hypoplastic and a right kidney that was normal or possibly even hypertrophic possibly slightly larger than we were expecting and this was likely congenitally caused animals can go on to live a very normal life with one kidney and can be born with one hyperplastic kidney however they may be slightly more prone to disease in the kidney because they don't have such potential backup in having two kidneys laughs
