# RCT-evaluation of Retzius-sparing Robotic Prostatectomy

**Official Title:** Robotic Retzius-sparing Radical Prostatectomy- a Randomized Controlled Trial Evaluating Transdouglas-RARP

**NCT ID:** [NCT03787823](https://clinicaltrials.gov/study/NCT03787823)

## Key Facts

- **Status:** UNKNOWN
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 186
- **Lead Sponsor:** Heidelberg University
- **Conditions:** Prostate Cancer, Urinary Incontinence
- **Start Date:** 2018-08-27
- **Completion Date:** 2020-11-30
- **CT.gov Last Update:** 2020-03-24

## Brief Summary

Prospective randomized blinded RCT comparing Transdouglas Prostatectomy to classical transperitoneal anterior radical prostatectomy

## Detailed Description

We will evaluate functional urinary and sexual recovery, oncologic outcomes and postoperative complications in patients over a follow up period of 12 months

## Eligibility

- **Minimum age:** 18 Years
- **Sex:** MALE
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* Indication for radical prostatectomy
* \>18 years old
* Literate
* Preoperatively continent
* informed signed consent for study

Exclusion Criteria:

* cT4-Cancer
* Withdrawl of consent to study
```

## Arms

- **Retzius-sparing RARP** (OTHER) — Arm B randomizes men with an indication for radical robotic Prostatectomy (RARP) to retzius-sparing transdouglas RARP
- **anterior transperitoneal RARP** (OTHER) — Arm A randomizes men with an indication for radical robotic Prostatectomy (RARP) to anterior transperitoneal RARP

## Interventions

- **robotic Prostatectomy (RARP)** (PROCEDURE) — Modification of robotic Prostatectomy Arm A classic technique/ anterior transperitoneal RARP Arm B Transdouglas Technique/retzius-sparing RARP

## Primary Outcomes

- **Urinary continence** _(time frame: 1 Week after Prostatectomy)_ — Pad use

## Secondary Outcomes

- **Resection margine** _(time frame: pathology report, approximately 1 week postoperatively)_
- **Urinary continence** _(time frame: 3, 6 and 12 months after Prostatectomy)_
- **Postoperative complications** _(time frame: First 12 months after Prostatectomy)_
- **postoperative PSA** _(time frame: 12 months)_
