CT KUB PLAIN

If you are experiencing sudden, severe pain in your side or back, your doctor may recommend an NCCT KUB scan. This is a specialized, rapid computed tomography (CT) scan designed to provide highly detailed images of your urinary system. Its primary purpose is to diagnose stones located in the Kidneys, Ureters, and Bladder (KUB). The term "Non-Contrast" is key; it means the scan is performed without injecting any intravenous dye. This makes the NCCT KUB scan a quick, safe, and minimally invasive diagnostic tool, providing your doctor with the clear answers needed to guide your treatment effectively.

At Cadabams Diagnostics, we are committed to using advanced imaging technology to ensure you receive a swift and accurate diagnosis, helping you get on the path to relief and recovery.

What is an NCCT KUB Scan?

An NCCT KUB scan uses a sophisticated combination of X-ray beams and advanced computer processing to create detailed, cross-sectional images of your urinary tract. Imagine slicing a loaf of bread to see every detail inside; a CT scanner does something similar with your body, but digitally and non-invasively.

The acronym "KUB" stands for the three main structures examined during the scan:

• Kidneys: The organs that filter waste from your blood to produce urine.
• Ureters: The thin tubes that carry urine from the kidneys to the bladder.
• Bladder: The muscular sac that stores urine before it leaves the body.

This scan focuses specifically on this region because it's where urinary stones most commonly form and cause problems. The reason it is performed as a "non-contrast" study is particularly important for stone detection. Kidney stones are typically made of calcium and are naturally very dense. This density makes them show up as bright white spots on a CT scan, allowing them to be easily identified without the need for contrast dye, which can sometimes obscure smaller stones.

Types of NCCT KUB Scan

The NCCT KUB scan is itself a highly specific type or protocol of a CT scan, tailored for one primary purpose: finding stones. The main variation within this procedure is the radiation dose protocol. The standard of care for a suspected kidney stone is a low-dose NCCT KUB scan. This approach was developed because stones are so dense that they can be seen clearly even with a lower radiation dose, which is a significant safety benefit for the patient without

When our expert radiologists at Cadabams Diagnostics analyze your scan, they are looking for much more than just the presence of a stone. They evaluate several critical parameters to create a comprehensive report that will guide your urologist's treatment plan. These include:

• Stone Presence & Location: The first step is to confirm if a stone exists and pinpoint its exact location—whether it's still in the kidney (renal pelvis or calyces), traveling down a ureter, or has reached the bladder.
• Stone Size & Number: The dimensions of the stone (or stones) are precisely measured in millimeters. This is a crucial factor, as smaller stones are more likely to pass on their own, while larger stones may require medical intervention.
• Stone Density: Measured in Hounsfield Units (HU), the density can help predict the stone's composition. For instance, high HU values often suggest a harder calcium oxalate stone, while lower values might indicate a uric acid stone. This information can influence treatment choices.
• Secondary Signs of Obstruction: The radiologist looks for tell-tale signs that a stone is causing a blockage. This includes kidney swelling (hydronephrosis) or the dilation of the ureter above the stone (hydroureter). The severity of these signs indicates how urgently treatment may be needed.

You may be referred for this scan for several definitive reasons, all aimed at resolving a painful and urgent medical issue.

• To accurately diagnose the definitive cause of acute flank pain or renal colic.
• To get a clear and unambiguous answer for a suspected case of NCCT KUB for kidney stones.
• To determine the exact size, shape, and location of a stone, which is essential for planning the most effective treatment, whether it's medical management, shockwave lithotripsy (ESWL), or surgery.
• To check for urinary tract obstruction, a serious complication of kidney stones that can lead to kidney damage if left untreated.
• To evaluate patients who have a history of stones, to see if new ones have formed.

When and Who Needs to Take an NCCT KUB Scan?

An NCCT KUB scan is the gold standard diagnostic test for patients who present with symptoms highly suggestive of kidney or ureteric stones. A doctor will typically order this scan if you are experiencing:

• Renal Colic: This is the most common reason. It is characterized by sudden, excruciating, and often wave-like pain in the flank (the side between your ribs and hip), back, or lower abdomen. The pain can radiate towards the groin.
• Hematuria: The presence of blood in the urine, which may be visible to the naked eye (gross hematuria) or only detectable under a microscope (microscopic hematuria).
• Unexplained Abdominal or Pelvic Pain: When other causes have been ruled out and a urinary stone is suspected.
• Associated Symptoms: Nausea, vomiting, fever, chills, or painful urination accompanying back or side pain can also prompt the need for this scan.

Benefits of Taking the Test

Opting for an NCCT KUB scan at Cadabams Diagnostics provides numerous advantages in a situation that demands speed and accuracy.

• High Accuracy: It is considered the international gold standard for detecting stones in the urinary tract, with a sensitivity and specificity of over 95%.
• Speed: The scan itself is exceptionally fast, taking only a few minutes from start to finish. This is vital in an emergency setting, providing rapid answers to relieve patient anxiety and allow for immediate treatment planning.
• Non-Invasive: Unlike some other procedures, it requires no needles, injections, or contrast dye. You simply lie on a table as it passes through the scanner.
• Actionable Results: The detailed report gives your doctor clear, unambiguous information to confidently recommend the best course of action for your specific situation.

Illnesses Diagnosed with CT KUB Plain

The primary focus of this scan is diagnosing stone disease, but it can also reveal other conditions.

Primary Diagnoses:

• Kidney Stones (Nephrolithiasis): Stones located within the kidney itself.
• Ureteric Stones (Ureterolithiasis): Stones that have moved from the kidney and are lodged in the ureter. This is the most frequent reason for ordering a CT scan for ureteric stones, as they are the primary cause of acute pain.
• Bladder Stones (Cystolithiasis): Stones that have either passed down into the bladder or formed there.

The scan can also incidentally identify other issues like urinary tract obstructions from causes other than stones, signs of kidney infection (pyelonephritis), and sometimes even unrelated but significant findings in the abdomen and pelvis.

Preparation for an NCCT KUB scan is minimal and straightforward.

• Fasting: Generally, no fasting is required. You can eat and drink normally before your appointment unless specifically instructed otherwise.
• Clothing: It is best to wear comfortable, loose-fitting clothes. You may be asked to remove any clothing with metal parts, such as zippers, belts, or underwire bras, as metal can interfere with the CT images. A hospital gown will be provided if needed.
• Hydration: Your doctor or the technologist may ask you to drink some water before the scan to ensure your bladder is comfortably full, which can help in visualizing it more clearly.

Pre-requisites

• A doctor’s referral or prescription is typically required to undergo the scan.
• Since this is a non-contrast study, no prior blood tests (like a creatinine test to check kidney function) are necessary.

Best Time to Take the NCCT KUB Scan

This test is most often performed as an urgent or emergency procedure when a patient presents with acute symptoms of renal colic. At Cadabams Diagnostics, our centers are equipped to handle these urgent cases 24/7. For less urgent follow-ups or evaluations, the scan can be scheduled at your convenience via an appointment.

Eligibility

Nearly all adults are eligible for an NCCT KUB scan. The main consideration is for patients who are pregnant. Due to the use of ionizing radiation, the scan is only performed on pregnant patients in rare situations where the diagnostic benefit is deemed to significantly outweigh the potential risks to the fetus, and alternative imaging methods like ultrasound are not sufficient.

Procedure for Taking an NCCT KUB Scan

Understanding the non-contrast CT KUB procedure can help ease any anxiety you may have. The process is quick and simple.

1. Check-in and Preparation: When you arrive at Cadabams Diagnostics, you will register at the front desk. A technologist will greet you, confirm your details, and explain the procedure. You may be asked to change into a hospital gown.
2. Positioning: You will be led into the CT scan room and asked to lie down on your back on the padded scanner table. The technologist will ensure you are positioned correctly and comfortably.
3. Scanning: The table will then gently slide into the center of the large, doughnut-shaped CT machine (called the gantry). The machine is open at both ends, so you will not be in a tight, enclosed space.
4. Breathing Instructions: The technologist will speak to you through an intercom from an adjacent control room. They will ask you to hold your breath for a few seconds at a time while the images are being acquired. It is important to lie very still during this time to ensure the images are sharp and clear.
5. Duration: The actual time the scanner is taking pictures is extremely short, often less than 30 seconds. The entire process, from entering the room to leaving, typically takes about 15-20 minutes.

Caution Before Taking the Test

It is absolutely crucial that you inform the technologist if you are, or if there is any possibility that you might be, pregnant. This is the most important piece of information you can provide to ensure your safety and the safety of your potential child.
