Urodynamic characterization of obese women with urinary incontinence undergoing a weight loss program: the Program to Reduce Incontinence by Diet and Exercise (PRIDE) trial

The purpose of this study was to describe urodynamic characteristics of overweight or obese women with urinary incontinence and explore the relationship between urodynamic parameters, body mass index (BMI), and abdominal circumference (AC). One hundred ten women underwent a standardized cough stress test and urodynamic study. Eighty-six percent of women had urodynamic stress incontinence and 15% detrusor overactivity. Intra-abdominal pressure (Pabd) at maximum cystometric capacity (MCC) increased 0.4 cm H 2 O per kg/m 2 unit of BMI (95% confidence interval [CI] = 0.0,0.7, p = 0.04) and 0.4 cm H 2 O per 2 cm increase in AC (CI = 0.2, 0.7, p
