USG KUB Test: Price, Purpose, Procedure, and Result [2026]

Bookmerilab/Ultrasound/

USG KUB, or Renal Ultrasound, is an ultrasound of the kidneys, ureter, and urinary bladder. This test examines and diagnoses any abnormality in the urinary system. Doctors may also recommend USG KUB as a diagnostic tool to assess the prostate gland in males. Ultrasonography, or ultrasound uses high-frequency sound waves to examine these organs. USG being a non-invasive (non-surgical) procedure, is helpful for healthcare professionals in looking for any abnormality in the nerves, tissues, and organs of the urinary system. USG KUB Scan price ranges between Rs 500 to Rs 1000.

Patients showing symptoms like frequent urination, abdominal pain, presence of blood in urine, or if kidney stones are suspected, a USG KUB scan is generally advised. Through such a scan, the doctors can easily visualize the patient’s urinary tract, enabling them to identify any infections, obstructions, or structural abnormalities. The test is very safe for people of all ages, is very quick, and does not involve any radiation, thus, it is also suitable for children and pregnant women. That’s why it is an indispensable instrument for early diagnosis and therapy management.

Purpose of USG KUB Scan Test

The KUB Ultrasound test is recommended in conditions such as:

  • To look for changes in kidney size: This test identifies the shrinkage (Kidney atrophy) or expansion in the size of kidneys. 
  • Obstruction in the urinary tract: This creates problems in the passage of urine. The obstruction in the urinary tract means the problem of resistance in the flow of urine during urination. 
  • Tumor or cyst in the Kidney: Tumors are round or oval-like cellular structures that may be cancerous or non-cancerous. Cysts are fluid-filled round pouches in the kidneys. 
  • To find the severity of urinary tract infection: The bacteria like E Coli and Staphylococcus cause UTIs. It relates to the inflammation or burning sensation in the urethra. 
  • Hydronephrosis: This medical issue indicates swelling in both kidneys. 
  • Symptoms of kidney injury: This may be due to the above-stated conditions or some autoimmune disorders like lupus.
  • Renal Stones: The accumulation of oxalate or uric acid crystals in the urinary tract that may form ureteric stones or renal calculi.
  • Evaluate the size of the prostate gland: This test determines the size of the prostate gland. The prostate gland is a male sexual part that produces sperm.
  • Monitor the post-treatment result: This test is beneficial in tracking the status of the pelvic organs like the Kidney, ureter, and bladder. 

What is examined in USG KUB?

  • Shape, size, and condition of the full bladder: For this, you shall drink the water and not urinate even if you feel the urge to urinate. 
  • Shape, size, and condition of the bladder after you empty the bladder: For this, you shall urinate completely. 
  • Size, shape, and condition of the kidneys and ureter for the Prostate gland: As discussed above, this test identifies tumours, stones, or structural issues. 

USG KUB Preparation 

The test does not require much preparation. You may need to fast for a few hours before the test and drink water before the procedure to keep the bladder full. The bladder can be examined properly when the bladder is full. No fasting is required for USG KUB.

Other instructions may be given depending on your health conditions. 

USG KUB Test Procedure

  • The radiologist performs the test. You will be asked to lie supine (on your back) with your lower abdomen exposed.
  • The examiner moves the transducer to the lower abdomen. The transducer emits high-frequency sound waves toward the body organs. 
  • You will be asked to empty the bladder to check the PVR value.
  • The images of the kidneys, ureter, and bladder are obtained, and the report is generated.
  • One can continue with a daily routine after the procedure.

Risks

There are no risks associated with USG KUB. The procedure is painless, non-invasive, and does not use dye. Since it is a noninvasive test that does not use ionising radiation, it is safe for pregnant women. 

USG KUB Test Result

The results of the USG KUB test will be interpreted by a trained healthcare provider, who will look for any abnormalities or abnormalities in the size, shape, and structure of the organs and tissues being imaged.

Normal KUB Ultrasound Result

The Normal USG KUB result suggests the absence of diseases of the kidneys like kidney cysts, kidney stones, and obstruction in the ureters.

Abnormal KUB Ultrasound KUB

The Normal USG KUB result suggests the presence of diseases of the kidneys like kidney cysts, kidney stones, and obstruction in the ureters. For example, if the test shows an enlarged kidney or a blockage in the ureter, it may indicate the presence of a kidney stone or other issues. Similarly, if the test reveals an abnormal shape or size of the bladder, it could be a sign of bladder cancer or another issue.

What is PVR in USG KUB?

After urinating, there is always some urine left in the bladder. Post Void Residual (PVR) is a measurement of the amount of urine left in the bladder after urination. If PVR is more than usual, it indicates an abnormality in the ureter or bladder. It is commonly measured using ultrasonography (USG) of the kidneys, ureters, and bladder (KUB). A normal post-void residual is less than 50 milliliters, while a high post void residual may indicate urinary incontinence, bladder outlet obstruction, or other urinary tract disorders

The Link between USG KUB and PVR?

The Role of the Kidney is to purify the blood and remove the waste material. The waste material urine is stored in a bladder. The residual urine in the bladder is measured using USG KUB, also called PVR ultrasound. A high PVR can be a sign of an issue with the bladder or urinary system, such as an obstruction or bladder dysfunction. There is a link between USG KUB and PVR in that USG KUB can help to identify any abnormalities or issues in the kidneys, ureters, and bladder that may be causing a high PVR. If an issue is identified through USG KUB, further testing or treatment may be necessary to address the issue and improve the PVR.

Comparison with other related investigations

  1. USG Abdomen: This ultrasound examines the entire abdominal area, including the liver, spleen, pancreas, and abdominal aorta. It is often used to diagnose abdominal pain, and abnormal liver function, or to monitor the progress of certain diseases.
  2. USG Pelvis: This ultrasound looks specifically at the organs in the pelvis, including the uterus, ovaries, and prostate gland. It is often used to diagnose pelvic pain, and infertility, or to monitor the progress of a pregnancy.
  3. CT Abdomen: This is a more detailed and specialized type of abdominal imaging that uses X-rays and computers to create detailed, 3D images of the abdominal organs. It is often used to diagnose more serious or complex conditions, such as cancer or organ damage.

Overall, USG KUB is a relatively quick and non-invasive way to examine the kidneys, ureters, and bladder, while the other abdominal ultrasounds and CT scans are more comprehensive and specialized.

Benefits of KUB Ultrasound

There are some benefits of KUB Ultrasound:

  • Non-invasive & safe: Sound waves are used, thus there is no radiation exposure.
  • Early detection: Assists in locating kidney stones, infections or bladder abnormalities.
  • Quick & painless: Offers on-the-spot results in a few minutes.
  • Scans urinary system: Proper inspection of kidneys, ureters, and bladder.
  • Condition support: Aided in the continuous monitoring of chronic kidney disease or prostate health.
  • Safe for pregnancy: Can be carried out without any harm to the mother or the baby.

Limitations

USG KUB test is noninvasive, painless, and relatively quick, making it a useful tool for diagnosing and monitoring kidney problems. However, there are a few limitations to keep in mind when considering an ultrasound KUB.

  1. Limited anatomic detail: Renal ultrasound images are not as detailed as those obtained from other imaging tests, such as CT or MRI, so they may not be as useful for identifying small abnormalities or for evaluating the structure of the kidneys in detail.
  2. Obesity and other factors may affect image quality: Factors such as obesity, gas in the intestines, and the presence of kidney stones can affect the quality of the images obtained during a renal ultrasound.
  3. Cannot evaluate the function of the kidneys: While a renal ultrasound can provide information about the size, shape, and location of the kidneys, it cannot evaluate how well the kidneys are functioning. Other tests, such as a blood or urine test, are needed to assess kidney function.
  4. Cannot detect all kidney problems: Some kidney conditions, such as early-stage kidney cancer, may not be visible on renal ultrasound. Other tests, such as a CT scan or biopsy, may be needed to diagnose these conditions

Conclusion

The results of a KUB ultrasound can provide valuable information to help diagnose and manage kidney-related conditions, such as kidney stones, kidney infections, and kidney abnormalities present at birth (congenital abnormalities). The test can also be used to monitor the progression of chronic kidney disease and to assess the effectiveness of treatment for kidney conditions. In conclusion, renal ultrasound or USG KUB is a useful tool for diagnosing and monitoring kidney problems, but it has limitations in terms of the level of detail it can provide and the conditions it can detect. It is important to discuss all available options with a healthcare provider to determine the best course of action for diagnosis and treatment.
