How accurate is ultrasound in detecting bladder cancer?
The accuracy of baseline ultrasound in bladder cancer detection per patient was 72.09% (31/43 patients), with a sensitivity of 81.81% (27/33), specificity of 40% (4/10), positive predictive value of 81.81% (27/33) and negative predictive value of 40% (4/10) (Figure 1).
Can you tell if you have bladder cancer from an ultrasound?
Ultrasound. Ultrasound uses sound waves to create pictures of internal organs. It can be useful in determining the size of a bladder cancer and whether it has spread beyond the bladder to nearby organs or tissues. It can also be used to look at the kidneys.
What does an ultrasound of the bladder show?
Bladder ultrasound can give information about the bladder wall, diverticula (pouches) of the bladder, bladder stones, and large tumors in the bladder. Kidney ultrasound can show if the kidneys are in the right place or if they have blockages, kidney stones, or tumors.
How do they test for bladder cancer?
Cystoscopy. Cystoscopy is the key diagnostic procedure for bladder cancer. It allows the doctor to see inside the body with a thin, lighted, flexible tube called a cystoscope. Flexible cystoscopy is performed in a doctor’s office and does not require anesthesia, which is medication that blocks the awareness of pain.
Is cystoscopy better than ultrasound?
While the tolerability of cystoscopy is relatively low, it is still superior to ultrasonography in the evaluation of the bladder as a possible source of hematuria. Painless hematuria usually is the sole presenting symptom in the majority of patients with bladder cancer.
Why would a doctor order a bladder ultrasound?
Doctors order bladder ultrasounds when there’s a concern about bladder problems, such as trouble with peeing or daytime wetting. A bladder ultrasound can show how much urine the bladder holds when it’s full and whether someone completely empties the bladder when peeing.
Can a pelvic ultrasound detect bladder problems?
Bladder ultrasound can detect bladder stones, bladder tumors (cancers) and bladder diverticula. It may also detect ureteroceles among other urological problems. A pelvic ultrasound can help identify bladder tumors, kidney stones, and other disorders of the urinary tract in both men and women.
Does ultrasound show bladder infection?
Ultrasound. If you have frequent urinary tract infections, your doctor may order an ultrasound to check the kidneys and bladder for irregularities that may require treatment. This test uses sound waves to create images of structures inside the body.
When an abdominal ultrasound is done Why is it advised to have a full bladder?
Gas. One of the main reasons why you need a full bladder is to avoid your pelvic region being full of gas during the scan. Ultrasound waves don’t travel well through gas which means they won’t be able to produce a clean image of your internal organs.

Imaging Techniques To Detect Bladder Cancer
Imaging techniques, which include ultrasound, computed tomography (or CT) scanning, magnetic resonance imaging (or MRI) and x-ray approaches, provide an important means of assessing the urinary tract, including the kidneys, and play an important role in the detection, diagnosis, and monitoring of bladder cancer.
Detecting bladder cancer with ultrasound
An ultrasound (which may also be referred to as a sonogram) uses high frequency sound waves to produce images of internal organs. Echoes, which are created as sound waves bounce off organs and tissues, produce computer images that provide information on the structure and movement of organs and the blood flow through vessels.
How do ultrasounds help detect and monitor bladder cancer?
An ultrasound of the urinary tract can help assess the size of a bladder tumor and whether a bladder cancer has spread. Ultrasound is able to differentiate between fluid-filled cysts and solid tumors, however, it cannot determine if a tumor is cancerous. Ultrasound can also be used to guide a biopsy needle to sample a suspected cancer.
Detecting bladder cancer with CT scans
A CT scan uses x-rays to obtain cross-sectional images of the body. Compared to a general x-ray test, which directs a broad x-ray beam from a single angle, the CT scan uses a number of thin beams to produce a series of images from different angles.
Other imaging approaches to detect or monitor bladder cancer
An MRI scan uses radio waves and magnets to produce more detailed pictures of soft tissues. MRI scans can show whether bladder cancer has spread to other tissues or to the lymph nodes. To improve the quality of the images it’s sometimes necessary to administer an intravenous dye.
