Overview

Urinary issues may elicit early symptoms that are usually thought to be trivial, such as frequent urination, difficulty emptying the bladder, discomfort in the lower abdomen, and incomplete voiding of the bladder. In order to establish what could lead to these symptoms, doctors may advise an ultrasound of the kidneys, ureters, and bladder. When the ultrasound also involves measuring the volume of urine left in the bladder after voiding, the method in question is referred to as the USG KUB with PVR.

City Imaging believes that knowing the purpose of a medical procedure can help patients cope with it with less worry. The cost of the USG KUB with PVR procedure varies between INR 999 and INR 3000. In this blog, we describe what the USG KUB with PVR procedure is about, what the reasons for the test are, how the test is administered, and more about the patient's pre- and post-scanning preparations.

What is USG KUB with PVR?

The meaning of USG KUB is Ultrasonography of the Kidneys, Ureters, and Urinary Bladder. It is considered to be a non-invasive imaging examination that uses ultrasound technology to produce pictures of the urinary system.

The term PVR means Post-Void Residual urine. It is used to refer to the urine that remains in the urinary bladder after urination.

In USG KUB with PVR, the sonologist assesses the condition of the urinary bladder and kidneys, as well as checks for possible health problems in the urinary tract, such as stones, infection, swelling, obstruction, or any other change. Measurements of the PVR help establish whether the bladder is emptying effectively.

The ultrasound method is often considered the best method in cases when imaging of the urinary system is necessary, since it does not imply any use of radiation.

Why is USG KUB with PVR done?

There could be various reasons that prompt a doctor to prescribe this examination. For example, it might be necessary if a patient is suffering from urinary problems or is suspected of having a urinary tract disorder.

Here are some of these cases:

• Difficulty starting urination
• Weak or interrupted urine flow
• Frequent urination
• Urgency to urinate
• Feeling that the bladder has not emptied completely
• Pain in the lower abdomen or side
• Blood in the urine
• Suspected kidney or urinary stones
• Recurrent urinary tract infections
• Suspected urinary obstruction
• Enlarged prostate-related urinary symptoms
• Evaluation of bladder emptying
• Follow-up of certain urinary tract conditions

What is PVR?

PVR stands for post-void residual urine; that is, this is the amount of urine which stays in the bladder after urination.

The bladder should normally empty itself when one urinates. However, under certain conditions, some residual urine can be present. An increased volume of residual urine may indicate the inefficient drainage of the bladder.

That is why measuring the PVR is helpful when a patient exhibits the symptoms of:

• Difficulty passing urine
• Weak urine stream
• Frequent urination
• Dribbling after urination
• Repeated urinary infections
• A sensation of incomplete bladder emptying

How is the Ultrasound performed?

Ultrasound of the urinary system with PVR is an uncomplicated and a non-invasive procedure.

The patient just needs to lie on the examining table. Only some amount of gel is applied to the abdomen area. A sonologist uses an ultrasound transducer to scan the abdominal region, so images can be taken.

The patient also may be asked to change positions or hold their breath for a short time. All this is necessary to get better-quality images. Therefore, no needles, injections or X-ray exposure is involved in this procedure.

Why Is a Full Bladder Important?

It is common for a KUB ultrasound test to require a comfortably full bladder. Patients are required to drink water before the ultrasound and hold their urine until the procedure is done unless otherwise instructed.

A full bladder allows for a better acoustic window for the test and helps the sonologist to visualise the bladder wall and surrounding organs better. Patients are to be careful about overhydrating themselves.

How is PVR measured?

The PVR portion is carried out after the patient has been instructed to empty his/her bladder.

Firstly, the sonologist assesses the bladder in the full stage. Following that, the patient gets the chance to void in the toilet next door.

After expressing urine, the patient comes back for another check-up. The sonologist assesses the volume of urine left in the bladder. The quantity is noted as post-void residual volume. The second measurement taken is very significant as it provides insights into the emptying of the bladder and the overall condition of the bladder.

What can USG KUB detect?

Ultrasound can provide useful information about several urinary tract conditions. It can detect:

• Kidney Stones
• Hydronephrosis
• Bladder Abnormalities
• Urinary Retention
• Enlarged Prostate

What does a high PVR mean?

An unexpected PVR level might suggest that the bladder is not emptying completely. Nonetheless, there is no one PVR number that can fit everyone.

The interpretation of the PVR measurement depends on and is affected by such factors as age and symptoms, medications, prostate condition, bladder functioning, and various other diseases. In case of the presence of excessive residual urine or constant urinary complaints, a physician may require the patient for further examination.

What does a normal PVR mean?

A PVR that is low or minimal usually indicates that the bladder is emptying properly.

However, the outcome should be considered in conjunction with the patient's medical conditions. It is possible for the individual to experience urinary symptoms when the PVR is within normal ranges.

How should you prepare for the Test?

Preparation is usually straightforward.

Patients may be asked to:

• Drink water before the examination.
• Arrive with a comfortably full bladder.
• Avoid urinating until the initial ultrasound is completed.
• Follow any specific instructions provided by the imaging centre.
• Inform the sonologist about relevant urinary symptoms and previous medical history.

Is USG KUB with PVR safe?

Absolutely. Ultrasound relies on high-frequency wave patterns, not ionizing radiation like X-ray, etc. Ultrasound is usually deemed a non-invasive and safe imaging method.

Generally, the investigation does not demand injection of contrast agents or any anesthesia. The scan, like any other diagnostic test, should be carried out because of medical necessity and should be interpreted by a medical professional.

How long does the examination take?

The length may depend on the person's health status, bladder fullness, and how many photographs are required.

Typically, urination follows the preliminary KUB scan before the PVR assessment. Thus, patients should plan for enough time for both examinations as opposed to thinking that the ultrasound will be over shortly after the first scan.
