About this study

Official title: Application of the Extra-fascial Robot Assisted Radical Prostatectomy Via the Posterior Approach in Intermediate or High Risk Patients: a Prospective, Multicenter, Double-blind, Randomized Controlled Study

This study was designed as a prospective, multicentre, double-blind, randomised controlled clinical trial. It aims to investigate the feasibility and safety of the posterior approach extrafascial technique and the anterior approach extrafascial technique in robot-assisted radical prostatectomy (RARP) for intermediate- and high-risk prostate cancer patients, to compare the oncological prognosis, functional prognosis, and safety of the two techniques in intermediate- and high-risk prostate cancer patients, and to provide evidence-based medical evidence for the choice of surgical treatment modality for intermediate- and high-risk prostate cancer patients.

This study was designed as a prospective, multicentre, double-blind, randomised controlled clinical trial. It aims to investigate the feasibility and safety of the posterior approach extrafascial technique and the anterior approach extrafascial technique in robot-assisted radical prostatectomy (RARP) for intermediate- and high-risk prostate cancer patients, to compare the oncological prognosis, functional prognosis, and safety of the two techniques in intermediate- and high-risk prostate cancer patients, and to provide evidence-based medical evidence for the choice of surgical treatment modality for intermediate- and high-risk prostate cancer patients.

About 118 subjects will be enrolled in this study in a total of 12 research centres across the country, and eligible subjects will be randomly assigned to the posterior approach extrafascial technique group and the anterior approach extrafascial technique group in a 1:1 ratio. All subjects routinely underwent comprehensive and systematic physical examination, laboratory tests and imaging examinations before surgery. After surgery, subjects were followed up at 1 week (visit 2, day 14±2), 1 month (visit 3, day 28±5), 3 months (visit 4, day 90±7), 6 months (visit 5, day 180±7), and 12 months (visit 6, day 360±14) after removal of the urinary catheter after the surgery, and then annually thereafter (visit 7), with urine control rate (defined as 0/ 1 pad) and 24-h pad weight questionnaires, PSA examination, International Prostate Symptom Score (IPSS), International Consultation on Incontinence Questionnaire Short Form (ICI-QSF), International Index of Erectile Function (IIEF), and related scores such as General Health-Related Quality of Life (EORTC QLQ-C30) and Prostate Cancer-Specific Quality of Life (QLQ-PR25). ) and other relevant scores; in case of clinical suspicion of local recurrence, imaging (pelvic MRI), whole-body bone imaging in patients with bone pain, and whole-body PET/CT if necessary. Subjects will be monitored and evaluated for adverse events (AE) throughout the trial. Subjects will participate in the clinical trial for an expected duration of approximately 1 year, after which they will be followed up periodically according to the usual follow-up strategy.

Study groups in NCT06434649
Study groupRoleWhat they receive
the posterior approach extrafascial technique groupExperimentalIn 2010, Italian urologist Dr Bocciardi carried out the first clinical practice of separation and resection of the prostate via the vesicorectal fossa, and this new surgical procedure was called Retzius-sparing Robotic Assisted Radical Prostatectomy (RS-RARP). In recent years, the posterior approach extrafascial technique of RS-RARP which has been used to widely resect the prostate and its surrounding fascia and neurovascular bundles, compared with RS-RARP, has been proposed to provide more complete resection of the tumour and reduce the rate of positive margins. The patients are included into the posterior approach extrafascial technique group who undergo the posterior approach extrafascial technique of RS-RARP.
Receives: Procedure: Extrafascial robotic assisted radical prostatectomy via posterior approach
the anterior approach extrafascial technique groupActive comparatorAnterior approach extrafascial technique is the most traditional method of radical prostatectomy for prostate cancer, in which the prostate is tied ventrally to expose the prostate by cutting the deep dorsal penile vein complex and the surrounding ligaments and fascia, and intraoperatively extensive resection is required to remove the prostate and its surrounding fascia and neurovascular bundles. The patients are included into the anterior approach extrafascial technique group who undergo the anterior approach extrafascial technique robotic assisted radical prostatectomy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. rate of continence

    rate of the preservation of urinary control function at 1 week after postoperative removal of the urinary catheter status

    Measured: 1 week after postoperative removal of the urinary catheter

  2. voiding score

    according to International Consultation on Incontinence Questionnaire Short Form, change in voiding score from baseline period at each visit viewpoint

    Measured: through study completion, an average of 1 year

  3. erectile function score

    according to International Index of Erectile Function, change in erectile function score from baseline period at each visit viewpoint

    Measured: through study completion, an average of 1 year

Secondary outcomes (4)
  1. the rate of positive specimen margins

    the rate of positive specimen margins after surgery

    Measured: after surgery, , an average of 1 year

  2. quality of life scores

    according to EORTC QLQ-C30, quality of life scores at each visit

    Measured: through study completion, an average of 1 year

  3. biochemical recurrence or imaging recurrence/progression

    biochemical recurrence or imaging recurrence/progression at each visit

    Measured: through study completion, an average of 1 year

  4. overall survival time

    deaths (overall survival time) at each visit

    Measured: From date of randomization until date of death from any cause, an average of 5 year

Questions about this trial

What is this clinical trial studying?

A study testing Extrafascial robotic assisted radical prostatectomy via posterior approach and Extrafascial robotic assisted radical prostatectomy via anterior approach in people with Surgical Procedure, Unspecified and Prostate Cancer, run by Ning Xu at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 13 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

rate of continence (time frame: 1 week after postoperative removal of the urinary catheter). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Apr 2026.
