Prostatitis (prostatis) refers to a prostate disease caused by various complex causes and mainly clinically manifested by urethral irritation symptoms and chronic pelvic pain. Prostatitis is a common disease of urinary surgery, although the incidence rate of prostatitis is high, the cause of prostatitis is still not clear, particularly non-bacterial prostatitis, so the treatment mainly aims at improving symptoms. In 1995, the National Institute of Health (NIH) established a new classification of prostatitis, type I: corresponding to acute bacterial prostatitis in the traditional classification method, type II: corresponding to chronic bacterial prostatitis in the traditional classification method, type iii: chronic prostatitis/chronic pelvic pain syndrome, type iv: asymptomatic prostatitis. Among them, nonbacterial prostatitis is much more common than bacterial prostatitis.

The methods for treating prostatitis include oral administration, physical therapy, injection therapy, and surgical methods. Different methods are selected for treating prostatitis due to different pathogenic reasons, however, currently, a puncture method is mostly adopted for determining prostatitis, but in the puncture process, operation trembling caused by psychological reasons of patients influences the entry of a puncture needle or experience of doctors influences the puncture effect, and the puncture success rate is low.
