Comparison of urethral sling surgery and vaginal non-ablative erbium: YAG laser treatment in Japanese patients with stress urinary incontinence: A case-matching analysis

The present study compared the effects of TVT and VEL on urinary incontinence using retrospective analysis of the UnIcoRN database, which is a comprehensive database in Japan that we have established to compare VEL to other treatments. Medical records of all registered cases were examined. This study was conducted in accordance with the Declaration of Helsinki, and the study protocol was approved by the Ethical Review Board of Kanagawa Association of Medical and Dental Practitioners (19006), complying with Japanese law. Opt-outs were solicited in 2019 via a joint website (http://unicorn-study.net/) for patients. The Urinary Incontinence Research Network (UnIcoRN) database was registered at University hospital Medical Information Network (UMIN) Center (R00004294).
