Urinary Tract Infections (UTIs). Urinary tract infections (UTIs) are a common type of infection caused by bacteria (most often E. coli) that travel up the urethra to the bladder. A bladder infection is called cystitis. If bacterial infection spreads to the kidneys and ureters, the condition is called pyelonephritis. (Sometimes lower UTI symptoms may be the only signs of kidney infection. 2  People at highest risk for such silent upper urinary tract infections include patients with diabetes, impaired immune systems, or a history of relapsing or recurring UTIs.). 3  An increased need to urinate at night.
Bacteria can enter the urinary tract from the outside to cause a UTI to come back, or a recurrent infection can be caused by bacteria that remain in the urinary tract after a previous infection.rine inside the urinary tract is normally sterile, but if any bacteria get in, it can cause an infection. UTIs are the second most common type of infection that people get, accounting for 8.3 million doctor visits every year in the United States.
