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

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.
