Athermal Nerve-sparing During Robotic-assisted Radical Prostatectomy Using a Hemostatic Matrix.

Prospective Randomized Investigation of Athermal Nerve-sparing During Robotic-assisted Laparoscopic Prostatectomy Using a Hemostatic Gelatin-thrombin Matrix

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.

Inclusion Criteria:

• Patient age >18
• Histologically proven prostate cancer ( Gleason <8; PSA<10ng/ml)
• Disease confined to prostate in clinical examination
• Preoperative IEEF-5-Score>20
• Patient is able to give informed consent

Exclusion Criteria:

• ASA IV-V
• Prior extensive abdominal surgery
• Signs for metastatic disease
• Known allergy against bovine material
• Patient is unable to give informed consent
