Like Bill, we ask that our pts avoid gassy foods and carbonated drinks the
day before their exam.  Additionally, we ask that they take a dose of Gas-X
the night before and the morning of their exam.
Can't tell you the last time we couldn't achieve a complete renal exam.
Agree with the lateral decubitus position.  If you angle up under the ribs,
you can see the entire renal artery in most patients.

Subject: Re: renal artery prep

Elaine,  I know that Miles Cramer had what I thought to be the ultimate prep
(you out there Miles???) However, it seemed to us that the more detailed we
made the procedure, the less compliance we had. Now, we simply tell the
patient to avoid gassy foods and especially carbonated beverages, hold
breakfast but drink lots of water and let them take their meds. The large
belly can be overcome by utilizing a lateral decubitus position, as can the
gas. (More than one way to skin a cat or see the renal artery). If the
patient is normal, it is almost never a problem. If the person is abnormal
or borderline and are very difficult due to gas, we will simply have them
come back a different day. Then you can do a face to face about the prep and
they seem willing to comply.
You should be able to visualize just about everyone with experience, a good
instrument, and most importantly patience! Good luck
