what causes urinary tract infections?

Bacteria: Utis are caused by bacterial migration into the urethra/bladder. Hygeine (not wiping front to back, etc) may be an issue. Urinating before and after intercourse helps to decrease risk of uti. Cranberry juice and increasing water intake may help prevent bacteria from sticking to the bladder wall. Recurrence may indicate anatomical or medical (diabetes, hiv, etc) problems and warrant a work up.

3 ways: There are 3 ways that bacteria invade and infect the urinary tract, ascending, hematogenous and lymphatic spread. Ascending means bacteria ascend the urethra into the bladder. Hematogenous spread is when bacteria in the blood stream seed into the kidney tissue. Lymphatic spread is one way bacteria can get from the bladder into the kidney. The other is up the ureter.
