Nowadays, if you open a newspaper or turn on the TV or radio, you will probably see and hear a medical advertisement or health knowledge lecture about prostatitis. Prostatitis has become a household name, but people are more aware of its harmful effects on their health, while the concept of prostatitis is vague. 1. What is prostatitis? The actual fact is that you will be able to get a lot of people to do the job. In other words, it contains a variety of diseases, but these diseases have a common clinical syndrome, but the current level of medicine can not be completely clear about their respective causes, so temporarily grouped together. These symptoms are mainly abnormal urination symptoms such as frequent urination, urgent urination, painful urination, difficult urination, incomplete urination, and discomfort or pain in the perineum, lower abdomen, penis, scrotum, and lumbosacral area. The poor naming of the disease name of prostatitis can easily lead to misunderstanding. First, it is easily understood as a single disease, and to avoid misunderstandings, experts are now calling for the use of the name prostatitis syndrome. Secondly, prostatitis can easily be misunderstood as a prostate infection, in fact, bacterial prostatitis that can be confirmed with certainty only accounts for 5% to 10% of prostatitis. The third is that prostatitis is easily misunderstood as a lesion in the prostate, and research has found that some patients have lesions not in the prostate at all, but in its surrounding tissues, so prostate type III is now called chronic pelvic pain syndrome, which we will discuss in detail below. 2. What is the incidence of prostatitis? The most common disease is chronic prostatitis, the prevalence of which is about 10% to 14%; among men aged 25 to 40, about 30% to 40% suffer from chronic prostatitis of varying degrees; it is the most common urological disease in men under 50 years of age, and ranks third in men over 50. And in autopsies, chronic prostatitis is even higher at 24% to 73%. According to statistics, about 50% of men have had symptoms of prostatitis at one point in their lives, and it is evident that prostatitis symptoms are quite common in adult men, and many patients with chronic prostatitis have become the main patients in urology clinics, accounting for 25%-33% of urology clinics. The actual fact is that you can find a lot of people who are not able to get a lot of money for the purpose of the actual project. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. In fact, chronic prostatitis has two age peaks, one for 30 to 39 years old and the other for 60 to 69 years old, and the incidence of 36 to 65 years old is higher than that of 18 to 35 years old. The reason why people have this misconception is because on the one hand, older people tend to have prostate enlargement and their symptoms mask the symptoms of prostatitis; on the other hand, it is due to the lack of awareness of prostatitis in older people, even among doctors. The incidence of prostatitis in children and adolescents is very low, and prostatitis in children is extremely rare. The actual fact is that there are a number of types of prostatitis. The actual fact is that there are a number of ways to classify prostatitis. 1978, Drach proposed to divide prostatitis into four types: acute bacterial prostatitis, chronic bacterial prostatitis, chronic non-bacterial prostatitis, and prostate pain, and this classification system is widely used in clinical practice and familiar to patients. However, there are some defects in the Drach classification system. In order to have a more scientific classification, the National Institutes of Health (NIH) proposed the NIH classification system in 1995, and in 1998 the International Prostatitis Collaborative Network (IPCN) proposed and affirmed this classification system again after 3 years of clinical and experimental application. the NIH classification system has had a great impact on the study of prostatitis and is now Clinically it has gradually. The NIH classification system divides prostatitis into 4 types: Type I is acute bacterial prostatitis, which as the name implies is an acute bacterial infection of the prostate; Type II is chronic bacterial prostatitis, which is a chronic bacterial infection of the prostate; Type III is chronic non-bacterial prostatitis/chronic pelvic pain syndrome, which is subdivided into Type IIIa (inflammatory) and Type IIIb (non-inflammatory); Type IV is asymptomatic inflammatory Type IV is asymptomatic inflammatory prostatitis, where the patient has no symptoms of prostatitis and is found to have leukocytosis in the prostate fluid or prostate puncture pathology biopsy for other diseases. Type I and II are bacterial prostatitis, accounting for 5% to 10%. Type IIIa, the chronic non-bacterial prostatitis of the Drach classification system, is the most common, with leukocytosis in prostatic fluid, semen or urine after prostate massage, but no bacterial growth in bacterial culture, accounting for about 60% of cases. Type IIIb, the Drach classification system of prostatodynia, has normal leukocytes in the prostate fluid, semen or urine after prostate massage and no bacterial growth in bacterial culture, accounting for about 30-35% of cases. The difference between type IIIa (inflammatory) and type IIIb (non-inflammatory) is that the former has increased leukocytes in the prostatic fluid, semen or urine after prostate massage, while the latter has normal leukocytes. The exact onset of type IV is not known. 5. What is meant by chronic pelvic pain syndrome? The careful reader will notice that the name of prostatitis type III is long, followed by an unfamiliar name called “chronic pelvic pain syndrome”, chronic pelvic pain syndrome is equivalent to the former chronic non-bacterial prostatitis and prostate pain in general, it includes inflammatory chronic pelvic pain syndrome and non-inflammatory chronic pelvic pain It includes inflammatory chronic pelvic pain syndrome and non-inflammatory chronic pelvic pain syndrome. The reason why experts propose the naming of prostatitis type III as chronic pelvic pain syndrome, while eliminating the names of chronic non-bacterial prostatitis and prostatodynia, is that current research has found that some patients have lesions not in the prostate at all, but in its surrounding tissues; chronic pelvic pain is the common and most characteristic manifestation of type III prostatitis; expanding the prostate to the pelvis can avoid misunderstanding and confusion among patients and doctors. The expansion of the prostate to the pelvis can avoid misunderstanding and confusion among patients and physicians.
