Hi! I would like to know how uncommon it is renal agenesia… I encountered a 14yold FN golden retriever who, as an incidental finding on scan, presents what appears to be a total lack of left renal structures. Initially I thought it was me, then I thought it had to be a nephrotic severely degenerated kidney that I just coul not find… But… I couldn’t find anything in the left area… Finally I realized there was no left renal artery at all and the left ureteric papilla at bladder was also missing… X-rays confirm lack of LK and no abnormal small mass structure is seen in the area…

Has anybody encountered anything like this?
