What causes urinary tract infections

Urinary tract infection is mainly caused by bacteria, viruses and other pathogens, while vesico-ureteral reflux, urinary system structural abnormalities, urinary tract tumors and other reasons can increase the risk of infection.

1, vesico-ureteral reflux

If the patient's ureter and bladder opening tissue structure is abnormal, it is easy to cause urine reflux to the ureter, resulting in urinary tract infection.

2, urinary system structural abnormalities

If the patient has renal dysplasia, ureter malformation and other problems, due to abnormal urinary system structure can not be discharged normally, easy to secondary infection serious urinary tract reaction.

3, urethral tumor

patients lead to urinary tract obstruction, easy to increase the risk of pathogen reproduction, resulting in urinary tract infection.
