Conclusion
Based on our long term follow-up results, the Ophira SIS had similar cure rates to the trans-obturator MUS among women undergoing surgery for SUI. This is the first study assessing long-term outcomes following randomization to a SIS and standard MUS treatment. However, results obtained with one SIS cannot be applied to another, so external validation studies, therefore, are also needed. We believe our results should be included in future meta-analyses to foster better understanding of the role of SIS systems in SUI management.
