Description: <jats:title>Abstract</jats:title><jats:sec><jats:title>Aims</jats:title><jats:p>To identify possible correlations of urethral retro‐resistance pressure (URP) with clinically and urodynamically proven stress urinary incontinence (SUI) and the outcome of anti‐incontinence surgery.</jats:p></jats:sec><jats:sec><jats:title>Materials and Methods</jats:title><jats:p>URP was measured using the Monitorr® system in women with clinically and urodynamically proven SUI without prolapse before and after anti‐incontinence surgery (colposuspension n = 8, tension‐free vaginal tape n = 6, tension‐free transobturator tape n = 34).</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Forty‐eight women (mean age 61.8 ± 8.9 years) were evaluated preoperatively and on average 10 weeks postoperatively. Mean URP was 75.6 ± 20.8 cm H<jats:sub>2</jats:sub>O preoperatively versus 75.4 ± 17.9 cm H<jats:sub>2</jats:sub>O postoperatively (<jats:italic>P</jats:italic> = 0.898). The type of anti‐incontinence surgery performed had no significant effect on postoperative URP. While no association was found between age and URP (<jats:italic>P</jats:italic> = 0.35), there was a positive correlation between URP and body mass index (BMI; r = 0.49, <jats:italic>P</jats:italic> = 0.0004). There was no correlation of URP with the preoperative pad test (<jats:italic>P</jats:italic> = 0.17) and urethral closure pressure at rest (<jats:italic>P</jats:italic> = 0.51). Finally, URP did not correlate significantly with the preserved length of the continence zone (0‐1/3‐2/3‐3/3) as determined by the urethral stress profile (<jats:italic>P</jats:italic> = 0.37–0.72) or with the objective cure rate (negative pad test).</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>Preoperative URP does not correlate with SUI in all women, has no predictive value, and does not correlate with the outcome of anti‐incontinence surgery. However, there seems to be an association with biomechanical factors such as obesity, which may open up a new area of application for URP measurement in urogynecologic diagnosis. Neurourol.
