About urinary tract and kidney infections

A urinary tract infection is usually caused by bacteria, and less often by viruses. Sometimes these bacteria come from the large intestine, possibly due to inadequate hygiene. Sexual intercourse can also introduce the bacteria (and also viruses) into the urinary tract.

The entire urinary tract from the kidneys to the bladder and then to the penis or urethra can be involved. A kidney infection can especially be a serious medical issue, and can also be due to viral infection.

Some UTI infections do not produce acute symptoms that are recognizable as an infection. Instead, they may create localized pain in the lower back or somewhere in the pelvis.


Some possible symptoms of a UTI include:

Strong urge to urinate
Sparse urination
Burning sensation when urinating
Cloudy color urine
Red colored urine if blood is present
A strong-smell in the urine
