Abstract

Introduction
Choice between TP or RP  for managing small renal masses is influenced the surgeon preference and the advantages of different surgical access during laparoscopic or robotic PN but still there is paucity of literature on this topic.
Design
A review was done for all cases done from 2021 till date. Surgical technique, indications , Average surgical time (overall and only robot time), ischemia time, blood loss, pathological stage, complications and hospital stay were recorded. A video demonstration of this technique with incorporation of indocyanin is shown in this video.
Results
A total of 14 cases were completed successfully without any operative complication or surgical Conversion. Indocyanin green was used for assessing perfusion and selective clamping .
Conclusion
RARPN is an effective approach to partial nephrectomy for  posterior renal masses with acceptable oncologic outcomes and convalescence. Surgeons’ preference and experience remain the tips of the balance in the decision towards the surgical access while performing a MI-PN
