What defines stage I prolapse?

Stage I prolapse is defined by the most prolapsed point of the pelvic organ being more than 1 cm inside the hymen. This classification is part of the pelvic organ prolapse quantification system (POP-Q), which provides a systematic way to evaluate and describe the severity of prolapse conditions.

In the context of stage I, the term "more than 1 cm inside the hymen" indicates that while there is a noticeable prolapse, it has not advanced to a point where it is close to the vaginal opening. This distinction is important in understanding the various stages of prolapse, as it helps clinicians determine the appropriate management and treatment options.

In contrast, other stages would involve more significant descent of the prolapsed organ. For instance, if the most prolapsed point is classified differently, it would suggest a progression to a stage where the organ is closer to or protruding through the hymen, indicating a greater severity of prolapse. Thus, option A accurately captures the specific criteria that define stage I prolapse in the context of gynecological assessments.
