Overall Study Notes Three major complications (all secur) - study stopped early. No validated questionnaires on incontinence, QoL, sexual function, or postoperative assessment. Overall, a helpful and applicable addition to the literature on mini-slings. Truly, only 2 sites, university based, poor f/u for an RCT ("call if you have problems") Surgeons had little experience in placement of Secure. data indicates that it is different than placing TVT or TOT with regards to achieving good anchorage, avoiding urethral and bladder injury and voiding dysfunction as tensioning is different. they should have had more experience, say 20-30 slings experience in order to compare fairly. applicability should not be to all mini-slings but only to secure placed in the hammock fashion. studies show other mini-slings such as mini-arc is easier and significantly less associated with complications. Major flaw is that cysto was not done on the secure slings. Cystoscopy should have been performed on all secure slings. especially when surgeons have only been proctored in placing 5 sling. Two of the major adverse events in the secure group would most probably have been identified intraoperatively and the study could have continued. bladder perforation occurred with TVT but rectified during surgery because it was identified with cysto.
