A bladder biopsy is a procedure to obtain a sample of your bladder tissue. It is usually done during a cystoscopy, a procedure that examines the bladder with a lighted scope. After the tissue is removed, it is examined under a microscope.
A small tool called a cystoscope will be inserted into the urethra and passed into the bladder. The bladder will be drained of urine. Next, the bladder will be filled with sterile water or saline solution to allow a better view of the bladder walls. Any suspicious tissue will be removed from the bladder wall for further testing.
