How is the prostate biopsy performed?
The procedure is performed on an outpatient basis under local anesthesia. The patient lies in the so-called lithotomy position (supine position with bent, slightly raised legs) or in the lateral position. The physician carefully inserts an ultrasound probe coated with lubricant into the patient’s rectum.
A thin hollow needle is inserted through a guide channel, which springs out by a spring mechanism and punches out a cylinder of tissue ten to fifteen millimeters in size (punch biopsy). Prostate biopsies can also be performed by what is known as an aspiration biopsy. In this case, the cells are aspirated through the hollow needle.
How much tissue is removed?
During an examination, the physician removes about ten to twelve tissue cylinders from different areas of the prostate within a few minutes. The samples are then examined for fine tissue under a microscope in a laboratory.
