title: Reliability testing of urodynamics, pressure flow studies and cough leak point pressure in women with urodynamic stress incontinence with and without detrusor overactivity.
abstract: Urodynamic studies which included cough leak point pressure (CLPP) and pressure flow studies were performed at two visits 2 weeks apart. Reproducibility between the two visits and also between the two diagnostic groups, urodynamic stress incontinence (USI) and urodynamic mixed incontinence (UMI) were analysed. Thirty-one women completed both visits, of those 14 had USI in both sets of urodynamic studies, 11 had UMI on both visits, six had USI on one visit and UMI in the other. The urodynamic variables of maximum cystometric capacity and CLPP have the most repeatability. Analysis in women with USI alone compared to USI with detrusor overactivity (DOA) showed that the repeatability for pressure flow parameters and CLPP was better in women without DOA, of which the CLPP was significantly different (p = 0.036). Urodynamic variables are inconsistent. This may reflect variations in urinary tract behaviour.
