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.

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.

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.
