Underestimation of pelvic organ prolapse in the supine straining position, based on magnetic resonance imaging findings.

Objective: Pelvic organ prolapse (POP) is clinically diagnosed in the supine position, where the effect of gravity is simulated by having the patients put strain on their pelvic floor. The objective of this study was to determine the degree of POP underestimation in the supine position based on magnetic resonance imaging (MRI) findings.

Methods: This prospective study was conducted with symptomatic POP grade ≥ 2 patients.
