Bladder Outlet Obstruction (BOO)
What is Bladder outlet obstruction?
A Bladder Outlet Obstruction (BOO) is a narrowing of the point at which the bladder opens into the urethra (internal opening inside penis) due to repeated infection, a cancer or injury to the area. The patient has difficulty in passing urine, particularly in starting the urinary flow, and they are usually unable to completely empty the bladder, which makes them prone to repeated urinary infections (cystitis).
How to diagnose bladder outlet obstruction?
The problem can be detected by using a cystoscope (examination tube passed into the bladder through the urethra) or an x-ray of the bladder after adding a dye by an intravenous injection (IVP – intravenous pyelogram) or through the urethra.
