i need to know if there is something in my stomach that will hinder the flow to my bladder/bowel I have had a scan on my bladder. after fasting for the night I emptied my bladder as per instructions between 5.30 / 6.00 then from 6.30 to 7.00 I drank a litre + of water had my scan at 8.00 with full bladder then was told to empty what I could and return for more scans I did not empty my bladder only a small dribble. the results came back and said 75% empty how can this be possible alan dadson
