[|Human|] liver is enlarged to 173mm and demonstrates fatty infiltration the gallbladder, biliary tree, pancreas and spleen are unrembarkable.  a 6 mm non-obstructing calculus is identified in the mid aspect of the right kidney the left kidney and aorta are unrembarkable - on another note the bladder is smoothly marginated - prevoid volume was 829 cc postvoid residual of 90 cc is above the upper oimits of normal which is 20 cc, however, this may be related to over-filling of the bladder on the prevo8id scan - can you decipher both for me - what happens if it was not overfilling
[|AI|]  HI, thanks for using Chat Doctor The post void urine volume can be influenced by the amount of urine in the bladder initially. When an ultrasound is to be done to assess post void volume, persons are advised to use large amounts of water. If there is a waiting period, there can be over filling of the bladder. As a result when asked to urinate, it may be difficult to empty the bladder fully resulting in a significant residual urine volume. The report is stating that the increased amounts seen in the bladder after urination may be as a result of the large amounts prior to urination. I hope this helps
