Sponsor St. Antonius Hospital Gronau
Start date July 2014
End date June 2016
Trial size 120 participants
Trial identifier NCT02163083, 2013-609-f-S, U1111-1157-6624


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).

United States No locations recruiting
Other countries No locations recruiting

Study Design

Allocation randomized
Endpoint classification safety/efficacy study
Intervention model parallel assignment
Masking open label
Primary purpose prevention
(No Intervention)
Lymphadenectomy will be performed as a standard procedure
A fluorescent dye (indocyanine green) will be ultrasound-controlled preoperatively injected in the prostate. During robot-assisted radical intervention by DaVinci ® robot the lymphadenectomy is performed using the fluorescence lymphography.
icg indocyanine green powder
Improvement of detection of positive lymphnodes

Primary Outcomes

The total number of detection rate of (positive) lymph nodes using ICG
time frame: during the surgery

Secondary Outcomes

Measurements of the time, that takes to remove the lymph nodes
time frame: During the surgery

Additional Information

Principal investigator Jörn H. Witt, MD
Description 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.
