The following is the problem of chronic prostatitis, but it is only a personal opinion, some may be biased, please only for reference. 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. If it protrudes from the rectum, hardens in texture and has nodules, it should be called enlarged, i.e. prostatitis. Traditionally divided into 1-3°, this degree depends on the experience of the doctor to distinguish. As for whether it is infectious or sterile, it is a bit complicated, my experience is: if it is in a long-term enlarged state, it is basically inflammatory, if only recently there is drinking, eating spicy, sexual activity after the enlargement, most are sterile – this depends on the patient symptoms are recent, or long-term, the most important is the performance of sterile For the prostate is enlarged, but soft and will not have nodules. 2, about the prostate fluid laboratory, my opinion: does not really reflect the state of inflammation, such as the prostate discharge duct opening back, the doctor’s fingers short, massage lighter, the patient due to pain tension, etc., may take less fluid or can not take, and for example, take the fluid is only the front section, may not or a small number of white blood cells, or less small bodies. At this point, it is necessary to judge the situation according to the anal examination. 3, modern ultrasound technology has a high reference value. The manifestations are: enlarged prostate (not enlarged large) – may only be length overload, not overall large volume, uneven echogenicity, enlarged inner gland, calcification or nodules, can be considered to have prostatitis.
