International urogynecological consultation chapter 4.1: definition of outcomes for pelvic organ prolapse surgery

Introduction and hypothesis: This manuscript of Chapter 4 of the International Urogynecological Consultation (IUC) on Pelvic Organ Prolapse (POP) reviews the literature and makes recommendations on the definition of success in the surgical treatment of pelvic organ prolapse.

Methods: An international group containing seven urogynecologists performed an exhaustive search of the literature using two PubMed searches and using PICO methodology. The first search was from 01/01/2012-06/12/2022. A second search from inception to 7/24/2022 was done to access older references. Publications were eliminated if not relevant to the clinical definition of surgical success for the treatment of POP. All abstracts were reviewed for inclusion and any disagreements were adjudicated by majority consensus of the writing group. The resulting list of articles were used to inform a comprehensive review and creation of the definition of success in the surgical treatment of POP.

Outcomes: The original search yielded 12,161 references of which 45 were used by the writing group. Ultimately, 68 references are included in the manuscript. For research purposes, surgical success should be primarily defined by the absence of bothersome patient bulge symptoms or retreatment for POP and a time frame of at least 12 months follow-up should be used. Secondary outcomes, including anatomic measures of POP and related pelvic floor symptoms, should not contribute to a definition of success or failure. For clinical practice, surgical success should primarily be defined as the absence of bothersome patient bulge symptoms. Surgeons may consider using PASS (patient acceptable symptom state) or patient goal attainment assessments, and patients should be followed for a minimum of at least one encounter at 6-12 weeks post-operatively. For surgeries involving mesh longer-term follow-up is recommended.
