Detection of Lymphnodes Using ICG During RARP

Detection of Lymph Nodes by Means of Intraoperative Fluorescence Lymphography Using Indocyanine Green (ICG) During the Radical Robot-assisted Prostatectomy

The purpose of this study is to investigate, whether the detection of lymph nodes by means of intraoperative fluorescence lymphography as part of lymphadenectomy in robot-assisted radical prostatectomy is higher than without the use of indocyanine green (ICG).

ICG is a fluorescent dye that fluoresces green bound to proteins under illumination in the near-infrared range. Using this dye allows to visualize lymphatic nodes, by being injected into the tumor or directly surrounding tissue.

Inclusion Criteria:

• Histologically confirmed locally limited prostate cancer;
• Intermediate or high risk tumor
• Recommended and planned prostatectomy;
• Completed and signed written consent;
• Voluntarily agreement to participate in this study
• Age of the study participants ≥ 18 years.

Exclusion Criteria:

• Allergic reaction to active ingredient (indocyanine green);
• Iodine allergy;
• Hyperthyroidism;
• High-grade renal impairment;
• High-grade hepatic insufficiency;
• Unwillingness to the storage and disclosure of pseudonymous disease and personal data
• psychiatric pre-existing conditions or other circumstances that make a cooperation by the patient in question
