Early DVC Ligation and Urinary Continence Recovery After RARP

September 22, 2020 updated by: Francesco Montorsi, IRCCS San Raffaele

Impact of Early Dorsal Venous Complex (eDVC) Ligation on Urinary Continence Recovery in Patients Undergoing Robot-assisted Radical Prostatectomy (RARP)

The aim of the study is to evaluate the impact of early deep venous complex ligation (eDVCL) in patients affected by clinically localized prostate cancer (PCa) undergoing robot-assisted radical prostatectomy with or without pelvic lymph node dissection. Overall, 312 patients will be randomized to the standard technique vs. eDVCL. The primary endpoint is represented by early urinary continence recovery. The secondary endpoints are perioperative outcomes, erectile function recovery and positive surgical margins.

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
312

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:

  1. Male patients, aged between 18 and 80 years old
  2. Planned to receive robot-assisted radical prostatectomy for prostate cancer
  3. Able to understand and willing to sign a written informed consent document
  4. On stable dose of current regular medication for at least 4 weeks prior to trial entry

Exclusion Criteria:

The participant may not enter the trial if ANY of the following apply:

  1. Life expectancy of less than 12 months
  2. Previous chemotherapy
  3. Previous brachytherapy or external beam radiotherapy
  4. Preexisting urinary incontinence defined as 1 or more pads per day
  5. Unstable cardiovascular disease
  6. Congestive Heart Failure (CHF)
  7. Clinically significant hepatobiliary or renal disease
  8. History of significant CNS injuries within 6 months
  9. Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the trial, or may influence the result of the trial, or the participant's ability to participate in the trial

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: Group 1
During robot-assisted radical prostatectomy after the posterior isolation of seminal vesicles, the Retzius space will be accessed and the endopelvic fascia will be incised. The DVC will be identified and incised. The DVC will be then selectively ligated using a V-lok 3/0 barbed suture. After the early DVC isolation, incision and ligation, the bladder neck will be incised and preserved when possible. A posterior nerve sparing approach will be then performed. During apical dissection, the urethral sphincter will be identified and carefully preserved. Posterior reconstruction and anastomosis will be then performed.
Procedure: Early DVC ligation
After the posterior isolation of seminal vesicles, the Retzius space will be accessed and the endopelvic fascia will be incised. The DVC will be identified and incised. The DVC will be then selectively ligated using a V-lok 3/0 barbed suture. This approach would allow for the preservation of the external urethral sphincter and for the identification and preservation of the neurovascular bundles that are located in the anterolateral aspect of the prostate. After the early DVC isolation, incision and ligation, the bladder neck will be incised and preserved when possible. A posterior nerve sparing approach will be then performed. During apical dissection, the urethral sphincter will be identified and carefully preserved. Posterior reconstruction and anastomosis will be then performed.
ACTIVE_COMPARATOR: Group 2
After the posterior isolation of seminal vesicles, the Retzius space will be accessed and the endopelvic fascia will be incised. The bladder neck will be then incised and preserved when possible. An inter-fascial or intra-fascial nerve-sparing technique will be then performed and the posterolateral aspect of the neurovascular bundles will be preserved. The DVC will be then isolated and selectively ligated using a V-lok 3/0 barbed suture. The anterolateral fibers of the neurovascular bundles will be then identified and preserved when possible. During apical dissection, the urethral sphincter will be identified and carefully preserved. Posterior reconstruction and anastomosis will be then performed.
