Ultrasound PVR (Post Void Residual) - Book Test at Low Cost

No, fasting is not required for ultrasound PVR. You can take your usual food and supplements unless otherwise specified by your healthcare professional.

Yes, you can drink water before the scan. But just before the scan, you need to empty your bladder as ultrasound PVR measures the amount of residual urine which is left in the bladder post-urination.

Ultrasound PVR is a painless, rapid, non-invasive and safe technique that is used to examine the urinary bladder for urinary retention.

Ultrasound PVR is a safe procedure with no side effects as it utilizes sound waves and a computer to produce images of the urinary bladder which help in the estimation of residual urine that remains in your bladder post-voiding.

There are several advantages of Ultrasonography/USG for the evaluation of residual urine in the urinary bladder over other techniques such as: 

• Rapid technique. 
• Non-invasive and painless.
• Cheap and affordable as compared to other techniques.
• Doesn’t utilize ionizing radiations.
• Do not require anesthesia unlike Bladder catheterization for PVR measurement.
• No need for intravenous/oral contrast agents which are usually used in the other imaging scans such as X-rays or CT (Computed tomography) scans.  
• Help in the evaluation of causes of urinary retention such as atonic bladder, mass in bladder, bladder stones, blockage in urinary tract, birth defects, neurogenic bladder, Prostate enlargement, trauma, urethral stenosis/narrowing or due to side effects of drugs.

Ultrasound/USG PVR test usually takes about 15-30 minutes. However, it may last longer depending upon the severity of condition and the associated co-morbid conditions.
