Primary Outcome Measures
NameTimeMethod
Percentage of Participants With POP-Q Stage Improvement Assessed by POP-Q Stage Improvement Based Upon Grading of Prolapse of the Anterior, Posterior, or Combined Anterior and Posterior Compartments Compared Between Baseline and One Year.1 year

The Pelvic Organ Prolapse Quantification system (POP-Q) is used to measure pelvic organ prolapse. POP-Q Stages are:

Stage 0: No prolapse is demonstrated Stage 1: The criteria for stage 0 are not met, but the most distal portion of the prolapse is greater than 1 cm above the level of the hymen Stage 2: The most distal portion of the prolapse is greater than or equal to 1 centimeter proximal to or distal to the plane of the hymen Stage 3: The most distal portion of the prolapse is greater than 1 centimeter below the plan of the hymen but protrudes no further than 2 centimeters less that the total vaginal length in centimeters Stage 4: The distal portion of the prolapse protrudes to at least (TVL-2) centimeters.

Improvement at one year is categorized as follows:

Cured: Pop-Q Stage reduced to 0 or 1, or improved by 2 stages from baseline Improved: POP-Q Stage \> 1, but improved by 1 stage from baseline Failed: POP-Q Stage stayed the same or increased in severity from baseline

Change in Patient Sexual Satisfaction From Baseline After Pelvic Organ Prolapse Repair With Axis Allograft Dermis Measured by Participant Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ-12) at 12 MonthsBaseline and 12 months

The PISQ-12 is the Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ-12). Sexual Function in women after pelvic organ prolapse repair with Axis Allograft Dermis measured by PISQ-12 at 6 months. The scores range from 0-48 with lower scores indicating better sexual function. Scores are calculated by totaling the scores for each question with (4) always, (3) usually, (2) sometimes, (1) seldom, and (0) never. Reverse scoring is used for items 1, 2, 3 and 4. The short form questionnaire can be used with up to two missing responses. To handle missing values, the sum is calculated by multiplying the number of items by the mean of the answered items.

Ratings for the Validated Surgical Satisfaction Questionnaire (SSQ-8) in Women Following Surgery to Correct Pelvic Organ Prolapse Repair With Axis Allograft Dermis at the 6 Week, 6 Month, 12 Month, 24 Month, and 36 Month Visits.6 week, 6 month, 12 month, 24 month, and 36 month visits

The Surgical Satisfaction Questionnaire (SSQ-8) is a validated questionnaire consisting of eight questions assessing participant satisfaction with the results of their surgery to correct urinary incontinence and/or pelvic organ prolapse. Scoring is implemented with the mean average of the 8 scores multiplied by 25, yielding a potential range of scores from 0 to 100. The higher the score is, the greater the degree of surgical satisfaction.

The Pelvic Floor Impact Questionnaire (PFIQ) measures impact of bladder, bowel, and vaginal symptoms on daily physical activity, travel, social/relationships, and emotional health. The PFIQ-7 has three scales: the Urinary Impact Questionnaire (UIQ-7), the Colorectal-Anal Impact Questionnaire (CRAIQ-7), and the Pelvic Organ Prolapse Impact Questionnaire (POPIQ-7). Response options range from 0 ("not at all") to 3 ("quite a bit"). Per scale, the mean score of answered items is multiplied by 33.3 to obtain the scale score (range 0-100) \[4\]. Summary scores are calculated by adding up the scale scores (range 0-300) \[4\]. Higher scores indicate more impact on daily activity.

The Visual analog scales (VAS) Questionnaire is a questionnaire that asks the participant to mark a place on a scale that aligns with their level of pain. Participants were asked to make a vertical mark on a 10 centimeter line marked with "No Pain" and "Worst Pain" at each end and the line was measured to the tenths decimal place. A lower score indicates less pain.

Change in Pelvic Floor Distress Inventory (PFDI-20) Questionnaire After Pelvic Organ Prolapse Repair With Axis Allograft Dermis From Baseline to 6 Weeks, 6 Months, 12 Months, 24 Months, and 36 MonthsBaseline and 6 weeks, 6 months, 12 Months, 24 Months, 36 Months

The Pelvic Floor Distress Inventory Questionnaire (PFDI-20) is a questionnaire with 20 questions that measures symptom distress and impact of health-related quality of life. The PFDI-20 has three scales:

Pelvic Organ Prolapse Distress Inventory (POPDI-6), Colorectal-Anal Distress Inventory (CRADI-8), and Urinary Distress Inventory (UDI-6). Each of the 3 scales of the PFDI-20 is scored from 0 (least distress) to 100 (greatest distress). The sum of the scores of these 3 scales serves as the overall summary score of the PFDI-20 and ranges from 0 to 300. Higher scores indicate more distress.
