PURPOSE OF REVIEW: Detrusor underactivity is a highly prevalent type of @entity409 in @entity1 and responsible for residual urine and decreased voiding efficiency. @entity1 with detrusor underactivity have an unfavorable outcome after prostatic surgery and do not have better long-term results than untreated detrusor underactivity @entity1 . Therefore, differentiation between detrusor underactivity and @entity1876 ( @entity1876 ) is crucial for the prediction of the outcome of prostatic surgery. RECENT FINDINGS: @entity1 with detrusor underactivity report more frequently about decreased/interrupted urinary flow, hesitancy, feeling of @entity1494 and/or @entity1494 compared with @entity1 with normal pressure-flow studies. Determination of and differentiation between detrusor underactivity and @entity1876 is only possible by pressure-flow studies. Threshold values for the diagnosis of detrusor underactivity have to be adjusted to the @entity1876 -grade. A nomogram using @entity1876 -index and maximum Watts factor is currently the most advanced tool to diagnose detrusor underactivity and/or @entity1876 ; values below the 25th percentile line indicate detrusor underactivity. It is desirable to establish tests to noninvasively diagnose detrusor underactivity. The combination of ultrasound detrusor wall thickness and bladder capacity can safely detect detrusor underactivity. SUMMARY: Careful assessment of @entity409 to discriminate between detrusor underactivity and @entity1876 should be done with pressure-flow studies, can avoid unsuccessful prostate surgery and helps in counselling @entity1 .
