Introduction: The three dimensions (3D) virtual reality is a widespread technology that started gaining field at medicine in the
last decades. This report demonstrates the use of pre-operative volumetric three dimensions rendering images to plan and guide
laparoscopic partial nephrectomies for intra-renal lesions.
Case reports: We present two cases, one with left partially endophytic upper polar mass and other with right endophytic upper
polar Bosniak III renal cyst. Three dimensional renderization was done using the open-source software: OsiriX®. It was utilized to
guide lesion specific resection in the operative field. Laparoscopic partial nephrectomy was performed uneventfully in both patients
in a relatively short timing and minimal blood loss.
Conclusion: Despite the incommodious application of the advanced 3D volumetric rendering in skillful surgical procedures, it
allows better expectation of surgical challenging tasks with resultant good surgical and oncological outcome.
