Urinary system infection is caused by:

There are three main ways of urinary system infection. 1. Local spread caused. When the patient has vaginitis and other diseases, it can spread directly to cause urinary system infection. 2. Blood line infection. When infection occurs in a certain part of the body, pathogenic microorganisms enter the blood. When they reach the urinary system, they can cause infection at the location. 3. Retrograde infection. The proportion of retrograde infection is the highest, for example, patients with benign prostatic hyperplasia, benign prostatic hyperplasia causes urinary system obstruction, urine retention in the bladder, causing infection. Patients with long-term indwelling catheter, fistula, bacteria from the drainage bag retrograde to the bladder, causing infection, at this time can also form white floc, for bacterial metabolites.
