Ultrasound Postvoid Residual
This test is performed to measure the amount of urine
that is left in your bladder after you have made an attempt to empty
This study is done with ultrasound. You will be asked to lie flat on
the exam table. The surface of your lower abdomen and pelvis will need
to be exposed. A towel will be placed along the waistband of your clothing
to protect it from the gel that is used for the study. Gel is placed
on the skin over your bladder. The ultrasound probe will be placed over
this area, and a recording will be made. Your care provider will review
the image and measurement with you.
You will have no side effects as a result of this study.
There is no special preparation for this study and you may resume your
usual daily activities immediately following the ultrasound.
