Maximum Isometric Detrusor Pressure to Measure Bladder Strength in Men With Postprostatectomy Incontinence

摘要

To describe the use of isovolumetric detrusor pressure (Piso) in men with postprostatectomy incontinence and compare the rates of detrusor underactivity using Piso versus other common measurements/surrogates of bladder strength.We evaluated 62 men leferred to our institution during a 3-year period for workup of postprostatectomy incontinence. During videourodynamic evaluation, the maximum Piso was measured using a mechanical stop test-with the examiner gently occluding the penile urethra during volitional voiding. Statistical analysis was performed to evaluate the effect of patient variables on Piso.The mean Piso was 54.6 +- 25.4 cm H2O. The Piso was <50 cm H2O in 40%. Isometric strength did n
