Pergialiotis and co-workers (2017) presented available evidence related to vaginal laser therapy as a treatment option for SUI. These investigators searched the Medline (1966 to 2017), Scopus (2004 to 2017), Clinicaltrials.gov (2008 to 2017) and Cochrane Central Register of Controlled Trials (CENTRAL) (1999 to 2017) databases for relevant studies in this field. They included all observational studies (prospective and retrospective, randomized and non-randomized) that reported outcomes on vaginal laser therapy as a therapeutic option for SUI. A total of 13 studies were included that recruited 818 patients who underwent laser therapy for SUI. The methodological quality of most included studies was low, as they were either individual case-control studies, case series or poor-quality cohorts (Oxford Level of Evidence 3b and 4). According to the existing evidence, laser therapy may be a useful, minimally invasive approach for treating SUI. However, the methodological limitations of included studies rendered them prone to significant bias, limiting their scientific integrity. The authors concluded that as the demand for minimally invasive approaches for treating SUI increases, it is expected that more patients will seek alternative treatments over current standards (mid-urethral slings). They stated that given the limitations of the existing studies, it appeared that conducting future trials is needed to elucidate this field.
