Objective.The aim of this study was to determine the surgical success and complication rates of mixed type of mesh materials compared with Prolene mesh in sling surgery over a 4-year follow-up period. Material and methods.Between 2005 and 2007, broad-based double-forced sling operations were performed in 144 women with stress incontinence using three different types of mesh material. Group I consisted of 48 patients in whom Vypro (R) mesh (Ethicon, USA) was used; group II of 48 patients in whom Ultrapro (R) mesh (Ethicon) and group III of 48 patients in whom Prolene (R) light mesh (Ethicon) was used. The patients' data and the success of the operation were evaluated based on the 24 h pad test, International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) scoring and Korman questionnaire analysis. Results.The ICIQ-SF score, the number of pads used and the results of 24 h pad test were statistically lower in group II at postoperative month 48 (p < 0.05). The rate of postoperative complications was lower in Group II than in the other groups (p < 0.05). The continence rates of groups I, II and III were 84.7%, 91.6% and 85.1%, respectively, in the 48th postoperative month. Conclusions.Ultrapro mesh can be used in sling surgery owing to its higher success rates, and lower vaginal and urethral extrusion and de novo urgency rates, which have also been shown in clinical studies.
