The prevalence and factors associated with previous surgery for pelvic organ prolapse and/or urinary incontinence in a cross-sectional study in The Netherlands.

OBJECTIVE: To estimate the prevalence and identify the factors associated with previous pelvic organ prolapse (POP) and/or incontinence surgery. STUDY DESIGN: In a cross-sectional study, all women who were aged 45-85 years and registered in eight general practices were invited to participate. They completed standardised questionnaires (the urinary distress inventory (UDI) and the defaecatory distress inventory (DDI)) and answered questions on previous pelvic floor surgery. RESULTS: Out of 2979 women eligible for this study, 1380 women were included. Previous surgery had been performed in 119 women. The prevalence of surgery increased with age, with a prevalence of 20.3% in the age group 76-85 years. Pelvic floor symptoms were more prevalent in women who had undergone previous surgery, with higher UDI and DDI scores. Factors associated with previous surgery were age, higher BMI, POP symptoms during pregnancy and previous hernia surgery. CONCLUSION: In The Netherlands, approximately one in five women will undergo surgery for POP and/or incontinence during her lifetime. The women who underwent surgery were more likely to have symptoms of pelvic floor dysfunction than those who did not undergo surgery.

Face validity and reliability of the first digital assessment scheme of pelvic floor muscle function conform the new standardized terminology of the International Continence Society.

AIMS: To test the face validity and reliability of a new digital pelvic floor muscle function (PFMF) assessment scheme that was designed on the basis of the recently standardized terminology of the International Continence Society. METHODS: Study participants comprised 41 women, age 18-85 years. Data on age and parity were obtained. Face validity of the new assessment scheme was tested by three senior and one junior pelvic physiotherapists, using the Delphi technique. PFMF of each woman was assessed four times by three specially trained pelvic physiotherapists. Examiners were blinded to parity and other findings. To test reliability, Kappa (K) was used for the dichotomous variables and Weighted Kappa (K(w)) for the items with more than two categories. RESULTS: Mean age of the women was 41 years (SD 10.5); 14 were nulliparous (34.1%), 6 primiparous (14.6%), and 21 multiparous (51.2%). The new assessment scheme showed satisfactory face validity and intra-observer reliability but low inter-observer reliability. CONCLUSIONS: The new assessment scheme based on the terminology of the ICS showed satisfactory face validity and intra-observer reliability. It can therefore be considered suitable for use in clinical practice. More detailed redefinition of the described outcome measures is necessary to improve the inter-observer reliability.
