This paper outlines the presentation, evaluation, and management of bladder outlet obstruction (BOO) in women as it relates to iatrogenic, anatomic, and neurogenic causes. Attention is given to the different diagnostic criteria used by various authors in their case series and studies. The lack of standardization with regard to the diagnosis of BOO in women emphasizes the fact that BOO is often a clinical diagnosis that is made by taking into account the history, physical examination, imaging of the lower urinary tract, and urodynamic pressure-flow parameters. Individual obstructive conditions including urethral stricture, postsurgical obstruction, primary bladder neck obstruction, pelvic organ prolapse, and neurogenic causes are addressed briefly.
