  Purpose

The purpose of this study is to evaluate the use of a hemostatic gelatine-thrombin matrix during athermal nerve-sparing prostate resection compared to conventional hemostasis using electrocautery in patients with localized prostate cancer and to investigate effects on postoperative erectile function and continence.

Primary Outcome Measures:
  • Postoperative erectile function [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Postoperative erectile function compared to preoperative status assessed validated questionnaires.


Secondary Outcome Measures:
  • Postoperative continence [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Postoperative continence compared to preoperative status assessed by validated questionnaires.

  • Intraoperative bloodloss [ Time Frame: During surgery ] [ Designated as safety issue: Yes ]
    Amount of blood collected in the suction during surgery.

  • Intra- and postoperative complications [ Time Frame: Perioperative period ] [ Designated as safety issue: Yes ]
    Intra- and postoperative complications associated to the study´s intervention.

Arms Assigned Interventions
Experimental: gelatine-thrombin matrix
Nerves-paring during robotic-assisted laparoscopic prostatectomy is conducted without mono- or bipolar electrocautery and clipping by using a hemostatic gelatine-thrombin matrix.
 Procedure: Application of a hemostatic gelatin-thrombin matrix
Hemostatic gelatin-thrombin matrix is used for hemostasis during nerve-sparing dissection of the prostate.
Sham Comparator: Control
Nerve-sparing during robotic-assisted radical prostatectomy is conducted with the use of mono- and bipolar electrocautery and surgical clipping.
 Procedure: Use of mono- and bipolar electrocautery and surgical clips
Mono- and bipolar electrocautery and surgical clips are used for hemostasis during nerve-sparing dissection of the prostate.
