The actual fact is that there is a lot of foam in the urine of prostatitis patients, but it is not necessarily prostatitis if there is foam in the urine. There are white blood cells and trace proteins in the urine of prostatitis patients, so during the urination process urine and water shock will produce a little foam, and at the same time can be accompanied by symptoms such as frequent urination, urinary urgency, and perineal area distension, but you cannot use foam in urine as a diagnostic criterion for prostatitis, it is not specific. A variety of conditions may have foam, such as kidney disease patients with increased protein content in the urine can appear foam, diabetic patients with excessive sugar in the urine can also appear foam, infected people can appear increased foam in the urine, these need to be based on routine urine laboratory tests, urine culture tests, routine examination of prostate fluid to confirm the diagnosis, but not based on the presence of foam in the urine as a definitive diagnosis. Sometimes foam in the urine can occur in a non-disease state, such as when the urine is excessively concentrated, but no urinary tract-related disease has occurred.
