Association of body mass index with hip and thigh pain following transobturator midurethral sling placement

Abstract

Objective: We sought to investigate the incidence of hip and proximal lower extremity pain following transobturator midurethral sling and evaluate the association between pain and body mass index (BMI).

Study design: This was a retrospective cohort study of all transobturator midurethral sling procedures from July 2008 through June 2009. The primary outcome was postoperative hip or proximal lower extremity pain.

Results: Four urogynecologists performed 226 procedures. The incidence of postoperative hip or proximal lower extremity pain was 15.5%. Women of normal BMI had a higher risk of developing pain than obese women (risk ratio, 2.51; 95% confidence interval, 1.01-6.22). While not statistically significant, overweight women were twice as likely as obese women to develop the primary outcome (risk ratio, 1.99; 95% confidence interval, 0.79-4.99).

Conclusion: Women of normal BMI have an increased risk of hip and proximal lower extremity pain following transobturator midurethral sling compared with obese women.
