Uroflow Test and Post Void Residual
Please arrive at the Urology Clinic with a
full bladder and a strong urge to urinate
Do not void for a few hours before you
arrive, if possible. You may want to drink
extra fluids before the test.
This test is used to assess voiding problems.
This test is quick and there are no catheters
or needles used.
You will start the test by voiding into a
special toilet that records the strength of
your stream, the time it takes you to void,
and the amount of urine you pass. You may
need to give a urine sample. You should
give this urine sample at the end of your
Post Void Residual (PVR) Bladder
This test is done after you have voided. The
purpose of this test is to find out if you are
emptying all the urine out of your bladder.
You will lie down on the exam table with
your lower stomach uncovered. Ultrasound
gel will be put on your stomach over the
area of your bladder. A wand will be placed
on the gel and moved gently over your
bladder to check for urine. This test takes
about five minutes.
