Calistar A vs. Calistar S - Comparative Cohort Retrospective Analysis of Single Incision POP Systems

March 6, 2020 updated by: Agustin Sampietro

Calistar A vs. Calistar S - Cohort Retrospective Analysis

The main objective of this study is to compare the initial outcomes and complication of two meshes implanted through a single incision to treat anterior and apical prolapses, Calistar A and a second-generation low weight mesh called Calistar S (Soft).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The main objective of this study is to compare the initial outcomes and complication of two meshes implanted through a single incision to treat anterior and apical prolapses, Calistar A and a second-generation low weight mesh called Calistar S (Soft). In such sense, objective and subjective parameters will be retrospectively tested to demonstrate the safety and effectiveness of this products. Safety will be assessed by register of complications and effectiveness will be evaluated by pelvic floor reconstruction and quality of life improvements.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Cured Participants According to Barber Criteria
Time Frame: Post-operative at 6 months
According to Barber criteria cure is defined if there are no points beyond the hymen (measure by POP-Q quantification), an absence of vaginal bulge symptoms and no re-treatment/interventions on year post procedure.
Post-operative at 6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Cured According to Objective Measure (POP-Q Quantification)
Time Frame: Pre-operative and post-operative at 6 months
Assessment of POP with POP-Q quantification. Number of participants cured according to POP-Q quantification. Success criteria: POP-Q stage equal 0 or 1.
Pre-operative and post-operative at 6 months
Quality of Life Status: Patient Global Impression Questionnaire
Time Frame: Post-operative at 6 months
Patient satisfaction with the experience and the result of procedure will be evaluated with the "Patient Global Impression" questionnaire. This is a visual analogue scale range 1 (very much worse) - 5 (very much improved). A higher score a better outcome.
Post-operative at 6 months
Adverse Events
Time Frame: Intra-operative and post-operative at 6 months
Register of adverse events. Clavien-Dindo classification
Intra-operative and post-operative at 6 months

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Quality of Life: PFDI 20
Time Frame: Post-operative at 6 months
Quality of life assessed with "Pelvic Floor Distress Inventory (PFDI 20)" questionnaire to evaluate the impact of urinary, prolapse and colorectal distress post-operative. The sum of the scores of these 3 scales serves as the overall summary score of the PFDI-20 and ranges from 0 (least distress) to 100 (greatest distress).
Post-operative at 6 months
Quality of Life: PISQ-12
Time Frame: Post-operative at 6 months
Quality of life assessed with "Pelvic Organ Prolapse/ Urinary Incontinence Sexual Questionnaire (PISQ-12)" to evaluate sexual function in women with pelvic organ prolapse and/or urinary incontinence post-operative. Higher PISQ-12 scores indicate a better sexual function. Maximum score is 48.
Post-operative at 6 months
