What is RGU?
RGU is a special X-Ray procedure done to study the urethra i.e., the terminal part of your urinary passage, to look for any abnormalities like stricture (narrowing) etc. It is usually done in males.
When is an RGU required?
What is done?
A local anesthetic solution is first introduced through the urinary outlet, in the reverse direction to the normal urine flow. Following this, the contrast solution (which looks opaque on x-rays) is pushed in the same manner and this is captured on an x-ray film to document the findings.This procedure is done under strict aseptic precaution. The contrast is injected into the urethra by placing a catheter at the tip of the penis.
Any specific advice?
There is no need of any preparation before this test.If you have an active infection of the urinary tract, indicated by burning sensation while passing urine, pus in the urine or fever, you will need to be treated for this before undergoing this test.
Will I have any pain (or) other problems during the procedure?
No, the procedure does not involve any injections. When the local anesthesia solution is introduced you will only have a discomfort. But if you have pain, immediately report to your Doctor and the procedure may be abandoned.This procedure does not involve any adverse reaction of the contrast agent used. Very rarely you may have reactions to the contrast (or) the local anesthesia itself. Very rarely this can be life threatening.
Will I have any problems following the procedure?
You may feel burning sensation while passing urine and may pass slight blood tinged urine once (or) twice following the test. In case the problems persist (or) you develop fever, scrotal pain, then immediately report to your doctor.
