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

What is a CT scan of the bladder?

A CT scan uses x-rays to make detailed cross-sectional pictures of your body. A CT scan of the kidney, ureters, and bladder is called a CT urogram. It can provide detailed information about the size, shape, and position of any tumors in the urinary tract, including the bladder. It can also help show enlarged lymph nodes that might contain cancer, as well as other organs in the abdomen (belly) and pelvis.

How does ultrasound help with bladder cancer?

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. This is usually an easy test to have, and it uses no radiation.

Why is bladder cancer found?

Bladder cancer is often found because of signs or symptoms a person is having. Or it might be found because of lab tests a person gets for another reason. If bladder cancer is suspected, exams and tests will be needed to confirm the diagnosis. If cancer is found, more tests will be done to help find out the extent ( stage) of the cancer.

Can a urine culture show cancer?

If you’re having urinary symptoms, this test may be done to see if an infection (rather than cancer) is the cause. Urinary tract infections and bladder cancers can cause the same symptoms. For a urine culture, a sample of urine is put into a dish in the lab to allow any bacteria that are present to grow. It can take time for the bacteria to grow, so it may take a few days to get the results of this test.

What type of tube is used for bladder cancer?

If bladder cancer is suspected, most doctors will recommend a cystoscopy. . A urologist uses a cystoscope, which is a long, thin, flexible tube with a light and a lens or a small video camera on the end. For details on how this procedure is done, see Cystoscopy.

What is the biopsy for bladder cancer?

A biopsy is when tiny pieces (called samples) of the abnormal-looking tissue are taken out and tested for cancer cells. If bladder cancer is suspected, a biopsy is needed to be sure of the diagnosis.

Is bladder cancer invasive or noninvasive?

This is very important in deciding treatment. If the cancer stays in the inner layer of cells without growing into the deeper layers, it’s called non-invasive. If the cancer grows into the deeper layers of the bladder, it’s called invasive. Invasive cancers are more likely to spread and are harder to treat.

What is the best way to test for bladder cancer?

Although radiological tests provide important information about the kidneys and the ureters, cystoscopy is the best method of evaluating the bladder and the urethra and diagnosing and monitoring bladder cancer. The cystoscope, a long thin camera, is inserted through the urethra into the bladder.

What is a CT urogram?

A CT urogram examines the upper urinary tract (kidneys and ureters) in detail. This test is good at finding tumors of the kidney, renal pelvis, and ureter, as well as other urologic abnormalities. It may identify kidney stones and hydronephrosis (swelling of the kidney that is often due to downstream blockage).

Can a urologist do a biopsy of the bladder?

Some urologist may have the ability to perform small bladder biopsies in the office. The tissue sample, or biopsy, is then sent to the pathologist for examination. A sample of the urine from the bladder is sent for analysis of the cells (called cytology) to determine if the urine contains any cancer cells.
