detrusor leak point pressure
Pronunciation: dee-el-pee-pee
Also written as: DLPP — detrusor leak point pressure
The intravesical pressure at which urine leakage occurs due to detrusor overactivity during urodynamic testing.
Full Definition
Detrusor leak point pressure (DLPP) is the intravesical pressure at which urine leakage occurs as a result of detrusor overactivity during urodynamic studies. This measurement is particularly important in pediatric patients with neurogenic bladder, as elevated DLPP (typically >40 cmH2O) indicates increased risk for upper urinary tract deterioration. DLPP helps guide treatment decisions regarding the need for anticholinergic therapy, botulinum toxin injection, or surgical intervention.
Usage
Usage note: Critical threshold is 40 cmH2O; distinguish from abdominal leak point pressure which measures stress incontinence.
In Context
- "The detrusor leak point pressure of 65 cmH2O indicated significant risk for renal deterioration." — urodynamics report
- "Treatment goals included reducing the detrusor leak point pressure to less than 40 cmH2O." — treatment plan
