Abstract

Objective

To evaluate preoperative abdominal leak point pressures (ALPP) with pre- and postoperative Incontinence Severity Index (ISI) scores.

Methods

A review of women who underwent a midurethral sling procedure between August 2004 and April 2006 was conducted. Eligible women completed preoperative urodynamic testing with ALPP determination and subjective incontinence severity assessment using the ISI before and 6 weeks after surgery. The ISI and ALPP relationship was analyzed using a Spearman rank correlation (Rho).

Results

Ninety-nine women met the inclusion criteria. Mean ALPP was 77.7 (25–172 cm H₂O). Mean improvement in ISI following surgery was 4 (−8 to 12). ALPP correlated with preoperative ISI (Spearman Rho −0.28, P=0.01), preoperative leakage frequency (ISI question 1) (Spearman Rho −0.32, P=0.001), and the ISI change 6 weeks postoperatively (ISI-delta) (Spearman Rho −0.23, P=0.002).
