Giant prostatic hyperplasia is a rare condition which can pose a number of clinical challenges.
Criteria for giant prostatic hyperplasia - some variation in definition:
(1) prostate weight > 500 g (most commonly used)
(2) prostate volume > 200 mL
(3) prostate volume > 500 mL
The prostate tissue should show a predominance of glandular and stromal hyperplasia, with adenocarcinoma or other tumor only a minor subcomponent.
Clinical features may include:
(1) hematuria that may be intractable
(2) urinary retention
(3) other lower urinary tract symptoms
Problems for patients who undergo prostatectomy:
(1) excessive blood loss
(2) urinary incontinence
(3) urinary bladder neck stenosis and urethral strictures
Because of problems associated with surgical prostatectomy, some view embolization as a viable option.
