High mucus filaments in a urine test can be seen in a number of situations. First, in most normal people, due to often high protein diet, drink less water, resulting in urine in the urinary salt material crystal precipitation, combined with physiological proteinuria, will be synthesized into mucus filament-like material. Secondly, sedentary people, often cycling people will also appear in the urine mucus filaments increased, mainly prostate long-term in the state of stasis, the prostate follicles will overflow prostate fluid, viscous, mucus filaments increased in the urine. In addition, can be seen in prostatitis, urethritis, the former is mainly the prostate long-term in the inflammation of the stimulation, the gland follicles secretion of prostate fluid increased. The latter is mainly pathogenic bacteria can stimulate the urethral bulbourethral gland and urethral mucosa, causing an increase in urethral bulbourethral fluid and urethral secretion, so there is an increase in mucus filaments in urine.
