Outcome of Mid-urethral Sling Procedures in Korean Women with Stress Urinary Incontinence according to Body-mass Index

ABSTRACT

PURPOSE: The aim of this study is to determine whether the outcome of the mid-urethral sling procedures may be influenced by the body-mass index in Korean women with stress urinary incontinence(SUI). MATERIALS AND METHODS: A total of 285 women 28 to 80 years old with a minimum follow-up of 6 months were included in the study. Patients were stratified as follows normal weight, 18.5~23 kg/m2; overweight, 23~27.5 kg/m2; obesity, 27.5 kg/m2 or higher. RESULTS: There was no significant complication. Bladder perforations were noted in 11 cases(4.9%, 3.8% and 2.2% in the normal weight, overweight and obesity group, p=0.449). There was no significant difference between the three groups for cure rate(p=0.173). The rates of postoperative urinary retention were 9.9%, 10.1% and 15.6% in the normal weight, overweight and obesity group(p=0.396). No significant difference was found between the three groups in the persistence of urgency(p=0.312). Seventy-nine patients(27.7%) had symptoms suggestive of voiding disorder, postoperatively. The incidence of these symptoms was not significant difference in the three groups(p=0.106). CONCLUSION: Our results demonstrate the feasibility and safety of the mid-urethral sling procedures for obese Korean women with SUI. Additional studies, including prospective randomized trials with longer follow-up, are needed to verify these findings.
