March 12, 2013 updated by: Bernardo Rocco, Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico

Does the Posterior Reconstruction of the Rhabdosphincter Improve Early Recovery of Continence After Robotic-Assisted Radical Prostatectomy? A Multicenter Randomized Controlled Trial. A Phase III Open-label Prospective International Multicenter Randomized Controlled Study for the Evaluation of the Efficacy of PRR, in Patients Subjected to RALP, Measured in Terms of Early Recovery of the Continence.

The present study is a multicenter randomized, controlled trial, whose aim is to verify the effect of the posterior reconstruction of the rhabdosphincter after robot-assisted radical prostatectomy on early recovery of urinary continence.

Study Overview

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Ages Eligible for Study

18 years to 80 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  • Age ≥18 and ≤ 80 years;
  • Biopsy proven clinically localized prostate cancer;
  • Informed consent obtained and signed;
  • Understanding of, and willingness to comply with, the study procedures.

Exclusion Criteria:

  • Pre-operative incontinence;
  • Salvage prostatectomy (defined as a prostatectomy prescribed after the failure of a different primary treatment);
  • Surgical posterior plane at the peri - rectal fat, without preserving an edge of the Denonvilliers;
  • History of psychiatric or addictive disorder or other medical condition that, in the opinion of the investigator, would preclude the patient from meeting the trial requirements;

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
EXPERIMENTAL: Posterior reconstruction of the musculofascial plate
These patients will receive reconstruction of the muscolofascial plate after radical prostatectomy. The reconstruction will be performed using two 3-0 Poliglecaprone sutures (on RB-1 needles) tied together, with each individual length being 12-15 cm. seven - Ten knots will be placed when tying the sutures to provide a bolster. The free edge of the remaining Denonvillier's fascia will be identified after the prostatectomy and approximated to the posterior aspect of the rhabdosphincter and the posterior median raphe using one arm of the continuous suture. As a rule, four passes will be taken from the right to the left and the suture is locked. The second layer of the reconstruction will be then performed with the other arm of the suture approximating the posterior lip of the bladder neck (full thickness) and the vesicoprostatic muscle to the posterior urethral edge and to the already reconstructed median raphe .This suture will be then tied to the end of the first suture arm.
Procedure: Posterior reconstruction of the rhabdosphincter
NO_INTERVENTION: Standard radical prostectomy

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
Urinary continence
Time Frame: 12 months
No urinary leakages, assessed with the EPIC Questionnaire.
12 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
Oncologic radicality
Time Frame: 12 months
PSA < 0,2 ng/ml.
12 months
Sexual potency
Time Frame: 12 months
Potency sufficient for intercourse, with or without use of PDE5i, assessed with the IIEF Questionnaire.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2013

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
