Abstract

The development of benign prostatic hypertrophy (BPH) and its associated obstructive influence on the male urethra continues to be the subject of intense study. Although direct cystoscopic and endoscopic examination can provide useful information on the physical state of the bladder neck and prostatic urethra, it is generally acknowledged that these techniques, in themselves, cannot be used to discern between normal and functionally obstructed subjects.26,29 It is also now generally accepted that the degree of obstruction bears no direct relationship to the size of the prostate.5,6,12,29 When prostatic hyperplasia is present, obstruction to flow in the proximal urethra may result from a loss of urethral distensibility as a result of impinging lateral lobes of the prostate, rather than a direct decrease in urethral caliber.12 Alternatively, detrusor-sphinctor dyssynergia may inhibit bladder opening during micturition so that voiding is impaired and urine is retained in the bladder.29
