Is obesity a risk factor for failure and complications after surgery for incontinence and prolapse in women?
OBJECTIVE
Obese women (body mass index 30 kg/m2 or greater) are considered to be at risk for postoperative complications and failure after stress incontinence surgery. We compare the outcomes in this population with nonobese women (body mass index less than 30 kg/m2) undergoing rectus fascia, porcine dermis and polypropylene sling procedures.


METHODS
We retrospectively identified 412 women with a body mass index less than 30 kg/m2 (94 autologous rectus fascia, 157 acellular porcine dermis, 161 transobturator polypropylene mid urethral sling) and 297 with a body mass index of 30 kg/m2 or greater (66 autologous rectus fascia, 114 acellular porcine dermis, 117 transobturator polypropylene mid urethral sling) who underwent sling procedures and other pelvic surgery. Evaluation included SEAPI assessment and quality of life questionnaires. Global cure equaled subjective SEAPI composite=0 and subjective satisfaction. Stress urinary incontinence cure equaled SEAPI (S)=0 and negative cough stress test. Chart review for perioperative data was conducted. Groups and outcomes were statistically compared.


RESULTS
All women had a minimum followup of 12 months. After controlling for body mass index preoperative demographics, SEAPI scores and quality of life indices were not statistically different within each sling group. Global cure and stress urinary incontinence cure rates were significantly higher for nonobese women in each sling group. Statistically significant improvement in SEAPI scores and quality of life indices was achieved for all groups, and there were no statistical differences within each sling group. Overall obese women had no increase in complications compared with nonobese women. The incidence of obstructive sequelae was statistically higher in nonobese women undergoing autologous rectus fascia and transobturator polypropylene mid urethral sling procedures.


CONCLUSIONS
Although cure rates are lower, obese women have significant improvements in quality of life after surgery for stress urinary incontinence. Obesity does not appear to be a risk factor for additional complications during sling and prolapse surgery.
