The presence of transurethral cystometry catheter and type of stress test affect the measurement of abdominal leak point pressure (ALPP) in women with stress urinary incontinence (SUI)

Abstract

Cough-induced stress test is significantly more sensitive than Valsalva to demonstrate urinary leakage. Cystometry catheter significantly increases cough and Valsalva ALPP whereas stress test can be false negative due obstructive effect of cystometry catheter in a group of patients. Stress test may be negative in the semi-supine position in about 14% of women complaining of SUI.
