Prone
Because the ureters curve anteriorly in the abdomen, the prone position can use gravity to better demonstrate the contrast in the renal collecting systems and ureters
Which way do the ureters curve in the abdomen?
Anterior
The ureters curve anteriorly, following the sacrococcygeal curve
Where should compression pads be applied when they are ordered for an IVU procedure?
At the distal ends of the ureters
