Occasionally, a suprapubic catheter (a tube placed through the belly area into the bladder) is needed to drain the bladder.
Long-term treatment of bladder outlet obstruction usually involves surgery. However, medical treatment options are available for many of the diseases that cause this problem. Discuss treatment options with your health care provider.
If diagnosed early, most causes of bladder outlet obstruction can be treated with great success. However, if diagnosis is delayed, permanent damage can result.
Long-term or high-grade bladder outlet obstruction can permanently damage all parts of the urinary system.
If you have symptoms of bladder outlet obstruction, call your provider. Early diagnosis is important and can often lead to a simple and effective cure.
The condition may be prevented by identifying and treating the cause of the blockage.
