Diagnostic Tests

Depending on the symptoms, a variety of tests will be ordered to help in the diagnosis of BPH. These may include:
  • A urine test to detect the presence of blood or infection.
  • A blood test to check how your kidneys are functioning.
  • An ultrasound of your abdomen to visualize the kidneys and bladder.
  • Cystoscopy in which a small telescope is passed through the urethra and into the bladder. This causes a small amount of discomfort.
  • Urine flow studies which help to identify if the symptoms are caused by a blockage in the urethra. To do this test you will urinate in the usual manner into a special container and the strength of the flow is recorded.
  • Urodynamic studies in which urine flow and bladder volume and pressure are measured via a small catheter which is passed into the bladder via the urethra.

A measure of the residual volume of urine left in your bladder after urinating normally. This can be measured by ultrasound over the bladder or by passing a catheter into the bladder and measuring how much urine remains in the bladder after urination.
