Responsiveness of quality of life measurements to change after reconstructive pelvic surgery.

Abstract

We sought to determine whether Incontinence Impact Questionnaire (IIQ-7) and Urogenital Distress Inventory (UDI-6) scores are sensitive to changes in clinical status after surgery for genuine stress incontinence (GSI) or pelvic organ prolapse (POP). Patients were included in this study if they had completed the IIQ-7 and UDI-6 scales and had undergone urodynamic testing before and 3 months after surgery for GSI or POP. Kruskal-Wallis tests and logistic regression were used to compare IIQ-7 and UDI-6 scores according to the outcome of surgery. Among 55 patients satisfying inclusion criteria for the study, 34 (62%) underwent Burch colposuspension, and 21 (38%) underwent suburethral sling procedures for GSI; 44 (80%) patients were subjectively continent after surgery. Thirty-four (62%) patients underwent surgical treatment of their POP; 31 (90%) were subjectively cured of their POP symptoms. Mean IIQ-7 and UDI-6 scores were lower in patients who were subjectively continent, and UDI-6 scores were lower in patients who were objectively cured of GSI. UDI-6 and IIQ-7 scores change after surgery for GSI and POP, with patients who are subjectively continent having lower postoperative scores on both scales.
