PURPOSE: To compare the outcomes and costs of stress urinary incontinence (SUI) surgery using a hand-made sling (Marlex®) versus a commerciallyavailable suburethral polypropylene sling (Advantage®). MATERIALS AND METHODS: Thirty-nine women with SUI due to bladder neck hypermobility and/or sphincter incompetence diagnosed by clinical examination and urodynamic studies were divided into two groups: group 1 (n = 19) consisted of patients from an academic center (Department of Urology, University Hospital of Federal University of Maranhao, and group 2 (n = 20) patients from private practice. The hand-made polypropylene suburethral sling was used in group 1 and the commercial sling in group 2. The patients were evaluated 30, 60 and 90 days after surgery. RESULTS: The mean duration of surgery was 43 min. in group 1 and 51 min. in group 2. No postoperative voiding difficulties were observed in group 1 (100%), as well as, in 94.7% of patients of group 2. A bladder catheter was not required in any of the patients of the two groups at the end of the study. The level of satisfaction was 100% in group 1, whereas, one patient of group 2 considered the surgery to be unsuccessful. Urodynamic studies showed low amplitude uninhibited contraction in 11.1% of patients of group 1 and 10.5% of group 2. No complications were observed in either group. CONCLUSION: The hand-made polypropylene mesh (Marlex®) can be used for sling procedures, saving costs and yielding results similar to that obtained with commercial sling systems.
