Category:  UWHC Departmental Policy   
Policy Number:  12.53    
Effective Date:  May 28, 2014   
Version:  Revision    
Manual:  Ambulatory    
Section:  Clinic Specific (Ambulatory)   

Ultrasound Post-Void Residual (US PVR) will be performed in the Adult Urology Clinic by Nursing, Radiology
Technicians, and Medical Assistant staff who have completed an initial observed competency and an annual written
competency (see attached related documents).


An US PVR is performed to help determine the amount of urine the bladder holds when it is full and/or whether
someone empties their bladder when urinating. This policy describes the process for performing and documenting
US PVR bladder scan.

A. Verify provider order for bladder scan.
B. The patient will be instructed to empty his/her bladder upon arrival to the clinic. A urine specimen will be
obtained if ordered. (Note: If uroflow test has also been ordered, it should be performed before the US
PVR. See Ambulatory Policy 12.55 - Uroflow Procedure in Clinics)
C. Explain procedure and purpose of the test, answer any questions.
D. Press the On/Off button on the bladder scan machine.
E. From the Main Menu, press the Scan button.
F. Select the appropriate Gender button. NOTE: if female who has had a hysterectomy choose male.
G. Palpate patient’s symphysis pubis. Apply ultrasound gel to the scan head.
H. Locate the patient icon on the scan head and make sure that when scan head is placed on patient’s
abdomen, the head of the icon points toward the head of the patient.
I. Place the rounded end of the scan head on the abdomen and aim toward the expected location of the
bladder. For most patients this means angling the scan head toward the coccyx.
J. Press and release Scan button on scan head. Hold scan head steady during the scan. When the machine
beeps the scan is complete.
K. Verify that the scan head was aimed properly by sitting the target shaped aiming icon located on the right
side of the LCD screen. The light represents the bladder and indicates the position of the bladder relative
to the scan head. The scan is accurate when the bladder image is centered on the cross hairs of the
aiming icon. If the bladder image is not centered, re-aim and rescan.
L. When the scan is accurate, press the Done button to view Scan results screen. Verify that the light
colored bladder image is completely contained in both vertical and horizontal scan planes. If bladder
image overlaps the edge of one scan plane or appears cut off, press Scan button to return to scanning
screen. Re-scan patient.
M. When accurate measurement achieved, press Print button twice to print exam.
N. With a washcloth or paper towel remove the ultrasound gel from the patient abdomen and the transducer
head. Clean the transducer with disinfecting towelette and allow to dry.
O. Document that procedure was performed with the date and time and the results of test in the patient's
electronic medical record (EMR) in the progress notes.

P. Notify the ordering provider that the scan has been completed.
Q. Complete the charge capture in the EMR.
