Bladder cancer is a malignant tumor occurs in the bladder mucosa, the main symptom of which is hematuria, while hematuria is easily mixed as a symptom of other urological diseases. This makes many patients miss the best treatment time for bladder cancer. Bladder cancer diagnosis can help patients detect the cancer earlier and take prompt treatments. Below, experts from Modern Cancer Hospital Guangzhou, China are introducing you the diagnostic methods of bladder cancer.
Diagnostic methods of bladder cancer
The procedure of routine examination is very simple, that is to look for red blood cells in the urine which has been centrifugated under high power microscope, so as to judge the occurrence of hematuria. This method is the only way to diagnose the occurrence of recessive hematuria. It can help to detect early stage bladder cancer. It is also used as a routine examination for high-risk group people.
2、Urine exfoliative cell examination
Urine exfoliative cell examination is an easy inspection method without trauma. It is very valuable to the diagnosis of bladder cancer and 85% of the bladder cancer patients show positive in the examination.
3、X-ray Angiography examination
X-Ray angiography examination can figure out the filling extent of the bladder, the infiltrative scope and depth of the tumor. Combined renal pelvis and ureter radiography can also judge whether the patient has occurred to hydronephrosis and ureter infiltration.
Cystoscopy examination can observe the location, size, numbers, shape and the infiltrative scope of the tumor etc. while patients should undergo biopsy simultaneously when they are receiving cystoscopy examination.
5、 Type-B ultrasonic examination
With the filling of the urinary bladder, the bladder wall mucosa will be extended thoroughly, thus, Type-B ultrasonic examination can measure the size & location of the tumor and the infiltrative scope of the mucosa. Transrectal ultrasonic scan can display the abnormity of the bladder wall in the basilar part of the tumor, and the echo of the tumor that is intruding into the bladder cavity, according to which, doctors can confirm the scope of the tumor.
When the bladder cancer tissue is spreading to the bladder cavity or bladder wall, CT examination can fully show the shape and the size of the tumor, and the accurate rate of this examination can reach to 80%.
