Common misunderstanding of prostate fluid examination "Why do I have more white blood cells in prostate fluid examination, and how is it getting heavier and heavier?" ! ""Why did my symptoms decrease after treatment, and the white blood cells in prostate fluid test increased? Is my condition worse or less? " "Why my symptoms are obvious, prostate fluid examination without white blood cells? Do I have chronic prostatitis? " .。 . . . . Patients often face similar confusion. This is mainly caused by misunderstanding in prostate fluid examination. Before Luo Kangping, a urologist in the Third Hospital of Peking University, the diagnosis of chronic prostatitis was mainly based on whether the white blood cells in prostatic fluid were greater than per high magnification 10. Judging the severity and curative effect of the disease is also based on the number of white blood cells in prostatic fluid. However, in recent years, many experts at home and abroad have published research reports and found that there is no positive correlation between the symptoms of patients with chronic prostatitis and the number of white blood cells in prostatic fluid; Many patients with chronic prostatitis have obvious symptoms, but there are no or few white blood cells in prostate fluid examination. After treatment, the symptoms were obviously relieved, white blood cells increased, and even accumulated in the whole field of vision. Therefore, the diagnosis of chronic prostatitis is not based on the number of white blood cells in prostate fluid test, but on symptoms (except asymptomatic prostatitis); Similarly, the evaluation of therapeutic effect is not based on the changes of white blood cells in prostatic fluid, but on the changes of symptoms. Prostate fluid examination is only a reference in diagnosis and treatment (except asymptomatic prostatitis). The author's own clinical experience also supports the above viewpoint. The number of white blood cells in prostatic fluid can not reflect the situation of chronic prostatitis well. For example, inflammation of the prostate leads to obstruction of the prostate, and there may be no or almost no white blood cells in the test. On the contrary, when the inflammation is relieved (symptoms are improved) after treatment, the glandular duct becomes unobstructed, white blood cells can be discharged from the glands, and the test value is also increased. Obviously, at this time, the condition is relieved rather than aggravated, but it is not completely good, at least in the glandular duct. So which part has been improved? It should be inflammation of prostate parenchyma outside the glandular duct. Losing an objective index will inevitably make people more confused about prostatitis. The author's experience, judging whether chronic prostatitis exists or not, on the other hand, has a good reference value, that is, digital examination of prostate and anus. Digital diagnosis of anus can understand the texture, size, tension and shape of prostate. These characteristics are very helpful to judge prostate inflammation and its changes.
