Early symptoms of prostate cancer are not obvious and can be easily overlooked, since it is a relatively low-grade malignant tumor that can be effectively controlled or even cured clinically if it can be detected and treated early in time. Aspiration biopsy of the prostate is the most reliable test for diagnosing prostate cancer. The materials are more fully obtained by perineal puncture, and the positive rate is obviously higher than that of the transrectal approach. Because the puncture needle passes longitudinally parallel to the rectum through the prostatic cusp, more periprostatic tissue specimens can be obtained.
