The triggers of urinary tract infections include low body immunity, the presence of urinary tract obstruction, female physiological structural factors and factors of medical origin.
1. low body immune function: when combined with diabetes, chronic kidney disease, tumors and other basic diseases, as well as long-term oral immunosuppressants and other drugs, the body’s ability to fight disease is poor, the urethra’s ability to reduce the defense of germs, easy to complicate urinary tract infection.
2. Urinary tract obstruction: when there are urinary stones (such as ureteral stones, bladder stones, etc.), tumors (such as kidney tumors, bladder tumors, etc.) compression and congenital abnormalities of the urinary tract structure (such as congenital hydronephrosis, congenital ureteral stenosis), the urinary tract is narrowed by the pressure, and the urine is not discharged well, which is easy to breed bacteria and cause urinary tract infections.
3. Female physiological structure factors: because the female urethra is short and adjacent to the vagina, it is easier for retrograde infections to occur during menstruation and sexual intercourse, thus resulting in urinary tract infections.
4. Medical factors: indwelling urinary catheter, cystostomy, cystoscopy and other medical operations may cause damage to the urinary tract epithelium, resulting in a decrease in the ability of the urethra to resist bacteria, thus leading to the occurrence of urinary tract infections.
To summarize, if you have a urinary tract infection, you need to consult a doctor in time.
