simple urinary tract infection

Simple urinary tract infection generally has no physiological or anatomical abnormalities, and has no history of urinary tract surgery and intubation. It is common in women. Most of them are propagated and spread by Escherichia coli entering urethra and vagina from anus or skin. The infection goes up to kidney and causes acute pyelonephritis. Sexual life is more conducive to upward infection of pathogens.
