Pelvic organ prolapse (POP), a common female condition, is the symptomatic descent of one or more of the anterior vaginal wall, posterior vaginal wall, the uterus (cervix), or the apex of the vagina from the normal anatomical position . Prolapse is strongly associated with childbirth, ageing and the menopause. Women with prolapse present with a variety of symptoms (vaginal, bladder, bowel, back, abdominal and sexual). Some of these symptoms are specifically associated with the descending pelvic organs protruding into the vaginal canal, for example feeling of a bulge or something coming down. Others, such as urinary and bowel problems, can co-exist and may be related to or be independent of the prolapse. It is important in research and clinical practice that we quantify such symptoms using standardised instruments with known psychometric properties.
Developing a symptom score
In 2000, at the outset of a programme of research on the conservative management of prolapse, we identified the lack of a simple prolapse symptom score which could be used as a continuous primary outcome measure in randomised controlled trials. To that end, we developed the Pelvic Organ Prolapse Symptom Score (POP-SS), and have published on its internal consistency, construct validity and sensitivity to change . We concluded that the POP-SS has good internal consistency and construct validity and is sensitive to change. Additional work has been undertaken on its test-retest reliability and minimal clinically important difference . The POP-SS has now been widely used, both in the research and clinical contexts. We have a large volume of data which we plan to interrogate to further develop this important tool [4-11].
Using the POP-SS
The POP-SS is a brief 7-item questionnaire that is acceptable to women and lends itself to use in both research and the clinical environment.
