Bladder outlet obstruction refers to any condition that blocks urine flow from the bladder into the urethra, the tube that carries urine out of your body. Bladder outlet obstruction has many possible causes, but the most common cause is enlarged prostate. Other causes include:

  • Prostate cancer
  • Narrowing of the urethra from infection, injury or surgery
  • Scarring of the bladder outlet from injury or surgery
  • Bladder stones

Bladder outlet obstruction may also occur as a side effect of certain medications, such as antihistamines and decongestants.

Bladder outlet obstruction can cause a wide range of symptoms, including weak or intermittent urine stream, difficulty starting urination, inability to urinate, and a sensation of not being able to completely empty your bladder. Treatment depends on the underlying cause. If not treated, bladder obstruction can lead to bladder stones, bladder infection and even permanent damage to the bladder muscle and kidneys.

If you have signs or symptoms of bladder outlet obstruction, consult your doctor. Prompt diagnosis and treatment is important to prevent serious complications.
