The most reliable test method to diagnose bladder cancer

What is the most reliable examination method for diagnosing bladder cancer? With the rapid development of current medical technology, the diagnosis of bladder cancer has reached a very accurate level. Patients can diagnose bladder cancer through clear examinations. So, what professional examinations do patients need to do before being diagnosed with bladder cancer? Let's ask relevant experts to introduce the examination methods of bladder cancer in detail.

What are the main tests for diagnosing bladder cancer?

(1) Urinalysis: can detect hematuria that is invisible to the naked eye.

(2) Bimanual bladder examination: It can examine the scope and depth of bladder tumor infiltration. Doctors and patients should cooperate during the examination and move gently to avoid bleeding.

(3) Cystoscopy: This is the main method for diagnosing bladder cancer. It can directly see the location, size, number, shape, and invasion of bladder tumors. Tumor biopsy should be performed at the same time during the examination.

(4) CT examination: It can detect tumors and enlarged lymph nodes with an accuracy rate of 80%, and helps to correctly stage bladder tumors.

(5) B-ultrasound: This examination is painless. The accuracy is proportional to the size of the tumor. Generally, tumors larger than 0.5 cm can be found. It is of auxiliary value in distinguishing bladder stones from tumors.

(6) Cystography: It is generally used to supplement the deficiencies of cystoscopy. If the tumor is too large, cystography can be used to view the entire picture. Multiple exposures can show that the bladder wall is stiff and cannot expand. Double contrast imaging shows the tumor more clearly.
