High mucus in routine urine tests can be seen in many cases: first, it may be normal, if there has been sexual intercourse before the retention of urine routine, it can directly lead to an increase in the viscosity of urine. This is mainly due to the male urethra, where there may be fluid secreted by many accessory gonadal organs that are not completely discharged, such as urethral bulbous gland fluid and prostate fluid. Secondly, the frequent occurrence of this condition requires consideration of pathological factors, common diseases such as urinary tract infections and prostatitis. Urinary tract infections are usually caused by pathogens such as E. coli, gonococcus, mycoplasma, and chlamydia that travel up to the urethra and bladder. The pathogens can proliferate and multiply within the mucosa, causing vasodilatation and congestion on the mucosal surface, a large exudation of white blood cells, and the formation of purulent secretions therefore an increase in urine mucus filaments.
