TL;DR: This is the first ever study to evaluate the role of an innovative intraoperative tool, near-infrared fluorescence (NIRF) technology in conjunction with intravenous indocyanine green (ICG) in identification of this “Landmark Artery” during NS RARP.
Abstract: Introduction and Objectives: The “Landmark Artery” has been shown to be a valuable landmark during nerve-sparing (NS) robot assisted radical prostatectomy (RARP) in improving the quality of the neurovascular bundle (NVB) preservation. Sometimes, this landmark can be challenging to find due to inexperience of the surgeon or anatomical challenges. We performed the first ever study to evaluate the role of an innovative intraoperative tool, near-infrared fluorescence (NIRF) technology in conjunction with intravenous indocyanine green (ICG) in identification of this “Landmark Artery” during NS RARP. We demonstrate our technique in this video. Methods: Ten patients underwent NS RARP. Before clamping the pedicle or dissection of the NVB, 0.75 ml of ICG was given. The NIRF technology was engaged on the robotic console and a period of 20–40 seconds was allowed for the ICG to enter the vascular system. The landmark artery was then observed bilaterally. After this time period, we switched back to the non-NI...

TL;DR: Large prospective multi-institutional randomized controlled trials are required to evaluate potency and continence outcomes of these techniques, using a rigid standard patient selection criteria and definition of potency are warranted in the new era of functional outcome-driven research.
Abstract: Nerve-sparing procedures during robot-assisted radical prostatectomy (RARP) have demonstrated improved postoperative functional outcomes. This article provides an overview of clinically applied prostatic neuro-anatomy, various techniques of nerve sparing (NS), and recent innovations in NS and potency outcomes of NS RARP. We retrieved and reviewed all listed publications within PubMed using keywords: nerve sparing, robotic radical prostatectomy, prostate cancer, outcomes, pelvic neuroanatomy and potency. Studies reporting potency outcomes of NS RARP (comparative and non-comparative) were analysed using the Delphi method with an expert panel of urological robotic surgeons. Herein, we outline the published techniques of NS during RARP. Potency and continence outcomes of individual series are discussed in light of the evidence provided by case series and published trials. The potency outcomes of various comparative and non-comparative series of NS RARP have also been mentioned. There are numerous NS techniques reported for RARP. Each method is complimented with benefits and constrained by idiosyncratic caveats, and thus, careful patient selection, a wise intraoperative clinical judgment and tailored approach for each patient is required, when decision for nerve sparing is made. Further large prospective multi-institutional randomized controlled trials are required to evaluate potency and continence outcomes of these techniques, using a rigid standard patient selection criteria and definition of potency are warranted in the new era of functional outcome-driven research.

TL;DR: The literature has shown that NS-RARP involves various techniques and approaches while there is a lack of randomized studies to suggest the superiority of one over the other, and a tailored approach for each patient is required for applying the NS approach during RARP.

TL;DR: The application of ICG with NIR fluorescence during RARP is helpful to identify the benchmark artery of neurovascular bundle and to improve the visualization of the vascularization and then the hemostasis.
Abstract: Introduction:Indocyanine green (ICG) is a fluorescent molecule that provokes detectable photon emission. The use of ICG with near-infrared (NIR) imaging system (Akorn, Lake Forest, IL) has been des...

TL;DR: Robot-assisted laparoscopic radical prostatectomy has become the standard of surgical care in the USA and around the world, and the surgical technique has evolved over time.
Abstract: Robot-assisted laparoscopic radical prostatectomy (RALP) has become the standard of surgical care in the USA and around the world. Over the past 18 years, we have performed 13,000 radical prostatectomies, and our surgical technique has evolved over time. We discuss this evolution and how it has helped us achieve optimal patient outcomes.

TL;DR: In this article, a Cox regression analysis of age, preoperative SHIM score, and grades of partial nerve sparing was performed to predict post-RALP potency in 7268 patients who underwent RALP between 2008 and 2018.
Abstract: Introduction: To identify factors affecting potency and to predict ideal patient subgroups who will have the highest chance of being potent after robot-assisted laparoscopic prostatectomy (RALP) based on nerve sparing (NS). Materials and Methods: Analysis of 7268 patients who underwent RALP between 2008 and 2018 with a minimum of 12 months of follow-up was performed. The patients were then categorized into four separate neurovascular bundle-sparing groups (NVB 1-4). A Cox regression analysis was used to determine the independent factors predicting potency outcomes. Cumulative incidence functions were used to depict the probability and time to potency between the NS groups stratified by age and preoperative sexual health inventory in men (SHIM). Results: Cox regression analysis of age, preoperative SHIM score, and grades of NS significantly predicted potency outcomes post-RALP. Patients with SHIM score ≥22 had a better chance of potency vs patients with SHIM NVB 3. Conclusions: Preoperative SHIM, age, and NS are the most influential factors for potency recovery following RALP. Patients with good baseline sexual function had similar postoperative potency, irrespective of their grades of partial NS. In patients with decreased baseline SHIM and older age, a higher grade of partial NS resulted in a significantly better potency compared with a lower grade of partial nerve spare.
