This is a randomized clinical trial comparing rates of de novo dyspareunia in women with and without vaginal dilator use following surgery for pelvic organ prolapse with traditional posterior repair. Our hypothesis is daily use of vaginal dilators from post-op week 4 through week 8 after posterior repair will reduce the rate of de novo dyspareunia.

Inclusion Criteria:

• Women who undergo pelvic organ prolapse surgery with a posterior repair
• Age ≥18 years
• Sexually active with heterosexual vaginal intercourse
• English speaking
• Available for 6 month follow up
• Able to complete study questionnaires
• Able to use dilators

Exclusion Criteria:

• Significant baseline dyspareunia
• Pregnancy by self-report or positive pregnancy test
• Prior pelvic radiation therapy
• Active pelvic infection, herpes, candidiasis
