[|Human|] Hello, I just got my results from an ulstra sound I had on my lower abdmonin the findings were as follows: 1) My right Kidney is 11.1 c.m is that normal size? 2) There is prominence of the left pelvocalyceal system, what does this mean? and what is it? 3)There is a post void residual of 9mls in the distended bladder measures 168mls, what is this? and what is a CT KUB to exclude ureteric calcus? please can you help me understand any of the above? thank you :) Kind Regards SOnja
[|AI|]  Hi. The mean dimensions of the kidneys upon maturation are: length-about 12 cm, breadth-about 6 cm and thickness-about 3 cm. The weight of one kidney averages about 120-150 g. Any decrease in size is abnormal. Prominence of the pelvocalyceal system means that maybe because of distal blocking (probably due to a stone)there is collection in the pelvocalyceal system and hence the CT scan of the kidney, ureters and bladder is suggested. This is a more precise form of investigation. The urine forms in the kidneys and flows into the bladder through the ureters. Any blockage in the ureters will cause accumulation of urine in the kidneys. Hope this helps you.
