Causes of pain while urinating
There are many causes of painful urination. In young girls, painful urination is usually caused by the irritation of the lining of the vagina. This can be caused by using certain types of soap or bubble bath, not wiping properly after using the toilet, or wearing tight-fitting or wet clothes for long periods of time.
Older girls can develop yeast infections as well. A boy may have pain when urinating if his penis is injured. Kidney stones and swelling in the bladder can also make urinating a painful experience, but these conditions are less common.
Urinary Tract Infection
The most serious cause of pain while urination is a urinary tract infection.
Urinary tract infection is simply the swelling (or inflammation) of the urinary tract, and is most often caused by bacteria.
There are two types of urinary tract infection: those infections that involving the bladder are known as cystitis and those infections that are in the kidneys are known as pyelonephritis.
In the first year of life, a urinary tract infection is more common in boys, but later in childhood it becomes more common in girls.
