Prostate puncture is performed to directly extract prostate tissue for pathological analysis and is the gold standard in the medical diagnosis of prostate disease. The puncture of the prostate generally consists of two routes, a perineal puncture and a transrectal puncture.
Prostate puncture is performed to directly extract prostate tissue for pathologic analysis and is the gold standard in the medical diagnosis of prostate disease. The first one is the perineal puncture, which is usually anesthetized, so the pain is paralyzed and not felt much, and the other is the transrectal puncture, while the rectal mucosa is not sensitive to the pain caused by the needle puncture, and the patient just feels the discomfort of the anal swelling, although the perineum of the prostate is painful, but the puncture is relatively fast and completely tolerable.
And the puncture needle is very thin, so penetration of the rectal wall and the prostate is less damaging, and local anesthesia with lidocaine gel is also used during the puncture to minimize rectal discomfort.
