Abstract

Introduction and hypothesis

The primary aim of this study was to evaluate the inter-examiner agreement of a previously described simplified pelvic organ prolapse quantification (S-POP) system in a multicenter, prospective, randomized, blinded fashion. Pelvic organ prolapse quantification (POPQ) system’s use in daily practice is hampered due to perceived complexity and difficulty of use. The S-POP was introduced in order to make the POPQ user-friendly and increase its usage (Swift et al. in Int Urogynecol J 17(6):615–620, 2006).

Methods

Five hundred eleven subjects underwent two separate pelvic exams in random order by two blinded examiners employing the S-POP at 12 centers around the world. Data were compared using weighted kappa statistics.

Results

The weighted kappa statistics for the inter-examiner reliability of the S-POP were 0.87 for the overall stage, 0.89 and 0.81 for the anterior and posterior vaginal walls, 0.82 for the apex/cuff 0.89, and 0.84 for the cervix and vaginal fornix, respectively.

Conclusion

There is an almost perfect inter-examiner agreement of the S-POP system for the overall stage and each point within the system.
