The possibility of using bladder wall thickness data as criteria for benign prostate hyperplasia intervention and as outcome criteria for benign prostate hyperplasia treatment has been proposed. Detrusor hypertrophy associated with bladder outlet obstruction can be imaged on suprapubic ultrasound, and bladder mass can be quantified from the evaluation of bladder wall thickness and bladder volume. Bladder wall hypertrophy has been found to be correlated with detrusor function.
