Figure 1. Pelvic Organ Prolapse Quantification (POP-Q) Stages.

Figure 1.

The POP-Q points are used to assess a woman’s stage of pelvic organ prolapse on examination. The locations of these points are shown in panel A. This panel shows normal anatomy, most frequently seen in nulliparous women. In this trial, eligible patients included women planning vaginal surgery for stages 2 through 4 vaginal prolapse, illustrated in panel B. Descent of POP-Q point C with the Valsalva maneuver more than one-third of the total vaginal length and location of POP-Q points Aa, Ba, Ap, or Bp with the Valsalva maneuver beyond the hymen were among the criteria for surgical failure in this trial.
