The prostate is a gonadal organ unique to men, and because of its anatomical location and functional specificity, it induces different diseases in men at different ages. In order to facilitate patient understanding and consultation, the Department of Urology of the Ninth People’s Hospital affiliated with Shanghai Jiaotong University School of Medicine gave a brief introduction to prostate disease, trying to describe the esoteric prostate disease and its hazards in easy-to-understand language. 1. What is the prostate gland? What part of the body is it located in? The prostate is the largest of the male genital glands, a substantial organ. The prostate gland is about 4cm in diameter (2.99~5.3cm), 3cm in diameter (1.48~4.58cm), 2cm in diameter (1.46~3.94cm) and 9.21~31.8g in weight. The prostate is located in the lower part of the bladder, adjacent to several organs such as the urethra, seminal vesicles, and vas deferens, and the urethra is traversed by the prostate. 2. What are the functions of the prostate gland? The actual fact is that some patients with severe symptoms of chronic prostatitis should not have their prostate cut off. （The actual endocrine function: the prostate is rich in 5a-reductase, which plays an important role in the pathogenesis of prostate enlargement. Therefore, 5a-reductase inhibitors such as Bollinger can make the hyperplastic prostate tissue shrink and improve the patient’s symptoms. (3) Control of urinary function: The prostate gland is close to the bladder neck and wraps around the urethra, participating in the formation of the internal urethral sphincter. When the urge to urinate occurs, the bladder contracts while the urethral sphincter relaxes, allowing for the smooth discharge of urine. (4) transport function: the prostate gland has urethra and two ejaculatory ducts through which the contents of the vas deferens and seminal vesicle glands can be discharged through the ejaculatory ducts and urethra when ejaculation occurs. As mentioned above, the prostate plays an important role in the body. The prostate is an indispensable organ when you are young, but it tends to grow and affect urination in old age. What are the prostate diseases that men are prone to get during their lifetime? The most common prostate diseases that can be encountered clinically are prostatitis, prostate enlargement and prostate tumor. It is a disease that occurs in men of different ages and has different characteristics, and requires appropriate treatment according to the characteristics of the disease. 4. What is prostatitis? 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. The actual fact is that there are four types of prostatitis according to the presence or absence of pathogenic bacteria, the length of the disease, and the characteristics of the symptoms, such as acute bacterial prostatitis, chronic bacterial prostatitis, chronic prostatitis/chronic pelvic pain syndrome, and asymptomatic prostatitis. 5, what are the symptoms of chronic prostatitis? The main reason for this is that there are many different symptoms of chronic prostatitis, some of which are asymptomatic, some of which are uncomfortable, and can be summarized as one or more different symptoms such as pain, abnormal urination, and sexual dysfunction. (1) Pain is mainly manifested as long-term and repeated burning sensation, pain or discomfort in the pelvic region, which can be seen in any part of the penis, urethra, scrotum, perineum, perineum, pubic bone or lumbosacral region. (2) Abnormal urination manifests as frequent urination, urgent urination, painful urination, incomplete urination feeling, and increased nocturia. (3) Sexual dysfunction is mainly manifested as erectile dysfunction, premature ejaculation, etc. 6, what are the causes of chronic prostatitis? The causes of chronic prostatitis are many and can be summarized as follows: (1) Infection by pathogens such as bacteria, chlamydia and mycoplasma. (2) Neuroendocrine abnormalities, anatomical abnormalities of the bladder neck, prostate, urethra and local pathological irritation leading to abnormal activity of the perineum and pelvic floor muscles, with persistent pain and involvement pain in the corresponding areas other than the prostate. (3) Prostatitis causes excessive contraction of the urethral sphincter, resulting in bladder outlet obstruction with residual urine formation, causing urine to flow back into the prostate, bringing pathogens into the prostate or directly stimulating the prostate, causing abnormal urination and pain in the pelvic region. (4) The predisposing factors for prostatitis also include smoking, alcohol consumption, spicy and stimulating food intake, inappropriate sexual activity, sedentary, and long-term urinary retention, causing long-term congestion of the prostate and chronic extrusion of the pelvic floor muscles. (5) Irregular life, fatigue, cold, etc. lead to a decrease in body resistance, can also cause chronic prostatitis. 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, but the quality of life of some chronic prostatitis patients is seriously affected. (1) Psycho-psychological and personality disorders: more than half of the chronic prostatitis patients have obvious psycho-psychological factors and personality traits change, such as anxiety, depression, insomnia, memory loss, hypochondria, hysteria, and even suicidal tendencies. These changes in mental and psychological factors can cause autonomic dysfunction and further aggravate symptoms. (2) Sexual dysfunction: Chronic prostatitis causes changes in the function of the hypothalamus-pituitary-gonadal axis and affects sexual function, resulting in poor erectile function and premature ejaculation. 8.What should I do if I have chronic prostatitis? The goal of treatment is to relieve pain, improve urinary symptoms and improve quality of life, and the evaluation of efficacy is based on symptom improvement. As the cause of chronic prostatitis, especially chronic non-bacterial prostatitis, is unknown, there are numerous treatment methods, and it can be said that each hospital, and even different doctors use different treatment options, which shows the difficulty and diversity of treatment for chronic prostatitis. The currently accepted treatment methods are mainly to take a-blockers, phytochemicals, anti-inflammatory and analgesic drugs, antidepressant and anti-anxiety drugs, M-blockers, Chinese herbal medicine and other two or several drug treatments, together with psychological and behavioral counseling, life and diet changes, prostate massage, prostate physical therapy and other comprehensive treatments, if it is clear that prostatitis is caused by pathogenic bacteria, while the need to add effective The actual antibiotics are also needed. 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. （The actual fact is that there are a lot of people who are not in a position to be able to get a good deal on a lot of things. (2) The lack of evidence-based medical evidence to confirm the efficacy and safety of prostate injection therapy, transurethral prostate irrigation therapy, and heat therapy, which is not recommended for unmarried or infertile people, are also being abused, causing not only economic waste but also serious harm to the physical and mental health of patients.
