    Abstract:
    AIM: To identify factors associated with unsuccessful pessary fitting in a large cohort of patients with symptomatic pelvic organ prolapse (POP). METHODS: This prospective observational study included 611 consecutive women with symptomatic POP in a tertiary-care hospital. Patients were initially fitted with a ring pessary with support. Those who failed were fitted with a Gellhorn pessary. A successful pessary fitting was defined as a patient who was fitted or refitted with a pessary and continued to use it 2 weeks later. Parametric and nonparametric tests were used for the data analysis. RESULTS: A total of 524 patients had successful pessary fittings (85.8% success rate). The success rate of the ring pessary with support was 57.9%, of the Gellhorn pessary was 69.1%. Stage IV prolapse (odds ratio [OR], 2.12), posterior compartment prolapse (OR, 1.92), genital hiatus (OR, 1.41), and vaginal introitus (OR, 1.40) were independent predictors of unsuccessful ring with support pessary fitting. Vaginal length (OR, 0.74/0.60 for ring with support/Gellhorn) and history of POP reconstructive surgery (OR, 2.50/2.58 for ring with support/Gellhorn) were independent predictors of both ring with support and Gellhorn pessary fitting. CONCLUSIONS: Stage IV prolapse, posterior compartment prolapse, large genital hiatus, and wide vaginal introitus were risk factors for unsuccessful fitting of ring pessary with support. Short vaginal length and a history of POP reconstructive surgery were risk factors for unsuccessful fitting of both pessaries.
