Bladder Outlet Obstruction
How is the condition diagnosed?
A person with this condition sometimes has urine left in the bladder after urinating. When this amount is large, or if the person cannot urinate at all, the healthcare provider can often feel the bulging bladder by touching the lower abdomen. The urine left in the bladder can be measured with an x-ray test known as ultrasound or by placing a tube, called a urinary catheter, in the bladder. Other tests that help the healthcare provider determine the severity of the condition include:
uroflowmetry, which measures the rate of urine flow
pressure flow studies, which compare the pressure in the bladder with the flow of urine during voiding
