Diagnosis and grading of outflow obstruction.
Urodynamic data from 66 male patients with obstruction due to benign prostatic hyperplasia were analyzed. Criteria for grading the severity of outflow obstruction based on uroflowmetry, post void residual urine, maximum bladder contraction (Pmax), and pressure during voiding (Pvoid) were developed. In selected cases, voiding cystourethrography also may be needed. These criteria help determine the need for prostatectomy. Unnecessary prostatectomies can then be avoided and can lead to significant reduction in mortality, morbidity, and health care expenses.
