It is a common problem in women to have burning sensation while passing urine. The reason is that the urinary tract gets infected. This Urinary Tract Infection is of 2 kinds, Upper urinary tract infection: Ureter (the tune connecting kidney to the urinary bladder) infection and kidney infection come under this type. Lower urinary tract infection: Urethra (the tube that extends from urinary bladder to urinary passage) infection and kidney infection comes under this type. In women, urethra infection is more common. It is because the urethra, the tube discharging urine, is very short.
