Urodynamic assessment: Urethral pressure profilometry and PTR

Stacey J Wallach, Donald R. Ostergard

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

For a person to be continent, the pressure in the urethra must exceed the pressure in the detrusor at all times. If bladder pressure should overcome urethral pressure, urine loss may result. Researchers have devised different tests to assess the relationship between urethral and bladder pressure. Their goal is to differentiate between patients with urinary incontinence based solely on an anatomic loss of urethral support, from patients with a loss of ability to maintain urethral pressure due to an incompetent urethral sphincter. Both urethral pressure profilometry and leak point pressure look at urethral resistance to voiding. However, urethral pressure profiles are static measurements along the length of the urethra thought to represent the intrinsic sphincter mechanism, while leak point pressures are dynamic tests of the amount of pressure it takes to overcome urethral resistance (1).
