Overactive bladder (OAB), also called urge incontinence, is a condition in which you experience a sudden, strong urge to urinate. This urge is the result of spasms, or contractions, in the bladder. Physical examinations of the abdomen, pelvic area, genitalia and rectum can help identify OAB, though other tests such as ultrasounds, x-rays and urinalysis are often needed for a proper diagnosis. Most often, several different tests will be conducted to rule out other causes. OAB can be treated with medication, surgery, therapy and in some cases, diet.

Cystoscopy

A cystoscopy utilizes a cystoscope, a thin tube with a lens, that allows the doctor to examine the inside lining of your bladder and urethra. The doctor will be able to look for any abnormalities that may or may not explain your OAB symptoms.

Ultrasound and X-ray

Your doctor may perform a pelvic or abdomenal ultrasound or x-rays. During these tests, your bladder is filled with a contrast fluid that will be visible. This allows your doctor to study the flow of urine in your bladder and determine if your symptoms result from an obstruction or a weakened bladder muscle.

Urinanalysis and Urodynamic Studies

Doctors may also conduct a urinalysis, a laboratory analysis of your urine, to look for a urinary tract infection that might cause OAB symptoms.

Urodynamic studies, which measure pressure and urine flow from the bladder, and volume tests, which measure the amount of urine left in the bladder after urination, may also be used to diagnose OAB.
