2:00 PM - 4:00 PM

Introduction & Objective :

Fluorescence-enhanced molecular imaging augmented with robot-assisted laparoscopic surgery can facilitate the performance of uro-oncologic cases. Indocyanine green (ICG) is a non-toxic, non-radioactive compound that enables deeper tissue penetration and improved visualization under near-infrared light. ICG can be given intravenously or via direct injection into the pathologic organ and its applications are diverse. In this video, we demonstrate utilization of fluorescence-enhanced molecular imaging in Robotic-assisted Uro-oncologic Surgery

Methods : ICG-NIRF has been used at our institution since 2010. Since then, we have used ICG in over 500 uro-oncologic cases, resulting in a constant refinement and precision of our surgical technique. In this video we demonstrate the many oncologic applications for ICG in the treatment of renal, adrenal, ureteral, prostate, and bladder pathologies.

Results :

ICG-NIRF applications for oncologic renal surgery includes assessing for adequate ischemia, viability of renorrhaphy, fluorescence patterns of renal lesions, and super-selective clamping when performing partial nephrectomy. ICG-NIRF can further facilitate cytoreductive nephrectomy by identifying vascular structures and assessing lymph node drainage patterns. In Nephroureterectomy, ICG can be instilled intravesically to ensure adequacy of bladder cuff and bladder repair, as well as assistance in lymph node dissection. For adrenal lesions, utilization of ICG-NIRF can provide histologic delineation of adrenal pathology and identification of vasculature and lymph node drainage patterns. In urothelial carcinoma of the ureter, ICG-NIRF can facilitate segmental resection and viability of the neo-cystotomy. For lower tract pathology such as bladder and prostate, direct injection of the pathologic organ can facilitate in structure identification and lymph node dissection. Furthermore, ICG-NIRF is quite useful in performing intracorporeal diversion as surgeons may assess anastomotic viability in real-time.

Conclusions :

ICG offers unique advantages for the robotic uro-oncologic surgeon. Mastery of these techniques can facilitate the performance of uro-oncologic cases.
