Mini-sling efficacy in obese versus non-obese patients for treatment of stress urinary incontinence.

BACKGROUND: The impact of obesity on single-incision has been object of concerns. The aim of the study was to compare the outcomes of MiniArc single-incision sling in normal weight, overweight and obese patients. METHODS: This retrospective study analyzed women with proven stress urinary incontinence (SUI). Patients were divided into three groups according to BMI: normal weight (group A), overweight (group B) and obese (group C). Objective cure rate was assessed with stress test and subjective cure rate was determined by ICIQ-SF and PGI-I scores. Postoperative overactive bladder syndrome and voiding symptoms were recorded. RESULTS: One hundred ninety-two patients were analyzed (A=97; B=68; C=27). Mean follow-up was 23.2 months without differences among groups. Estimated blood loss and operative time were not influenced by BMI. No bladder perforation were observed. Objective cure rate (A=87.6%; B=86.8%; C=81.5%) and subjective outcomes resulted similar irrespective of BMI class. De novo onset of overactive bladder syndrome and voiding symptoms were reported without significant differences among groups. CONCLUSIONS: The current study showed that single-incision sling Miniarc seems to be an effective treatment irrespective of BMI. Operative data, complications, objective and subjective outcomes were similar for normal weight, overweight and obese women.
