Primary Outcome Measures:
  • Effectiveness in assessment of the pelvic floor tissue conditions. [ Time Frame: Two years. ] [ Designated as safety issue: Yes ]
  • Ability in early detection of prolapse conditions. [ Time Frame: One Year ] [ Designated as safety issue: Yes ]

Enrollment: 158
Study Start Date: December 2011
Study Completion Date: November 2013
Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Asymptomatic women presenting at various ages without prolapse condition.
Symptomatic women presenting with prolapse conditions with no prior surgeries and women presenting with surgery scheduled with or without prior surgery.

Detailed Description:
  1. The device will detect significant differences in tissue elasticity and anatomy for women with normal pelvic floor versus women with prolapse stage 1.
  2. The device will detect significant differences in tissue elasticity and anatomy for patients before and after reconstructive surgery.
  3. The device will detect significant differences in tissue elasticity and anatomy among 3 groups of patients with prolapse stages 1, 2 and 3.
  4. The device will detect significant differences in tissue elasticity among 3 control groups with normal pelvic floor conditions (nulliparous women at age 21-30, parous women at age 31-40, and postmenopausal women).

Ages Eligible for Study:   21 Years and older
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population

The patient pool will comprise of 200 female patients.


Inclusion Criteria:

  • Subject is female of 21 years or older AND HAS AT LEAST ONE OF THE FOLLOWING
  • No evidence of pelvic organ prolapse and no prior pelvic surgery
  • Stage 1 or greater pelvic organ prolapse affecting one or more vaginal compartments and no prior pelvic surgery
  • Stage 2 or greater pelvic organ prolapse affecting one or more vaginal compartments and reconstructive surgery is scheduled

Exclusion Criteria:

  • Active skin infection or ulceration within the vagina
  • Presence of a vaginal septum;
  • Active cancer of the colon, rectum wall, cervix, vaginal, uterus or bladder;
  • Ongoing radiation therapy for pelvic cancer;
  • Impacted stool
  • Recent (less than three months) pelvic surgery;
  • Significant pre-existing pelvic pain including levator ani syndrome, severe vaginismus or vulvodynia;
  • Severe hemorrhoids
  • Surgically absent rectum or bladder
  • Significant circulatory or cardiac conditions that could cause excessive risk from the examination as determined by attending physician
