Show moreBackground: There is a paucity of data describing the ability of margin, ischemia, complications, score (MIC) and trifecta in predicting long-term outcomes of robotic assisted partial nephrectomy (RAPN). Objective: To compare a novel trifecta (negative margins, no significant complications, and perioperative estimated glomerular filtration rate [eGFR] decrease <30%) versus standard MIC as predictors of oncologic and functional results in a large series of RAPNs. Design, setting, and participants: : Between 2009 and 2019, a multicenter dataset was queried for patients with nonmetastatic renal masses who underwent RAPN at eight participating institutions. Intervention: RAPN. Outcome measurements and statistical analysis: MIC and trifecta achievement were determined for the overall cohort and a subgroup undergoing off-clamp RAPN (ocRAPN), respectively. The overall survival (OS), recurrence-free survival (RFS), and new onset of end-stage renal disease (ESRD; defined as eGFR <30 ml/min) probabilities were assessed by the Kaplan-Meier method. Cox regression analyses were used to identify predictors of OS, RFS, and ESRD. For all analyses, two-sided p < 0.05 was considered significant. Results and limitations: Out of 1807 patients, MIC and trifecta were achieved in 71.1% (n = 1285) and 82.6% (n = 1492), respectively, and once restricted to the ocRAPN cohort, in 95.6% (n = 625) and 81.6% (n = 534), respectively. On Kaplan-Meier analysis, both MIC and trifecta achievement predicted higher OS and lower ESRD probabilities (all p < 0.014), while only trifecta achievement was a predictor of RFS probabilities (p = 0.009). On multivariable Cox regression, MIC did not predict any of the endpoints independently, while trifecta achievement was an independent predictor of higher OS (hazard ratio [HR] 0.4, 95% confidence interval [CI] 0.18-0.86; p = 0.019) and lower ESRD development probabilities (HR 0.32, 95% CI 0.15-0.72; p = 0.005). Conclusions: Trifecta, initially described as comprehensive measures of perioperative outcomes, needs to stand the test of time. Compared with MIC, the recent trifecta was an independent predictor of clinically significant endpoints, namely, survival and ESRD development probabilities. Patient summary: Our novel trifecta represents a reliable method for estimating survival and development of end-stage renal disease after robotic-assisted partial nephrectomy.

Show morePurpose The aim of the present study is to investigate the impact of the near-infrared (NIRF) technology with indocyanine green (ICG) in robotic urologic surgery by performing a systematic literature review and to provide evidence-based expert recommendations on best practices in this field. Methods All English language publications on NIRF/ICG-guided robotic urologic procedures were evaluated. We followed the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) statement to evaluate PubMed(R), Scopus(R) and Web of Science (TM) databases (up to April 2019). Experts in the field provided detailed pictures and intraoperative video-clips of different NIRF/ICG-guided robotic surgeries with recommendations for each procedure. A unique QRcode was generated and linked to each underlying video-clip. This new exclusive feature makes the present the first "dynamic paper" that merges text and figure description with their own video providing readers an innovative, immersive, high-quality and user-friendly experience. Results Our electronic search identified a total of 576 papers. Of these, 36 studies included in the present systematic review reporting the use of NIRF/ICG in robotic partial nephrectomy (n = 13), robotic radical prostatectomy and lymphadenectomy (n = 7), robotic ureteral re-implantation and reconstruction (n = 5), robotic adrenalectomy (n = 4), robotic radical cystectomy (n = 3), penectomy and robotic inguinal lymphadenectomy (n = 2), robotic simple prostatectomy (n = 1), robotic kidney transplantation (n = 1) and robotic sacrocolpopexy (n = 1). Conclusion NIRF/ICG technology has now emerged as a safe, feasible and useful tool that may facilitate urologic robotic surgery. It has been shown to improve the identification of key anatomical landmarks and pathological structures for oncological and non-oncological procedures. Level of evidence is predominantly low. Larger series with longer follow-up are needed, especially in assessing the quality of the nodal dissection and the feasibility of the identification of sentinel nodes and the impact of these novel technologies on long-term oncological and functional outcomes.
