15. Bladder outlet obstruction

These notes are for use together with the Colley Model.

Bladder outlet obstruction (BOO) occurs when there is an obstruction to the flow of urine from the bladder. Examples of this are an enlarged prostate gland in men and severe uterovaginal prolapse in women. Urethral problems are more common in male patients, but it must be remembered that urethral stricture and stenosis can occur in women too.
