<b><i>Background:</i></b> Preoperative surgical planning before partial nephrectomy (PN) is a time-consuming and fragmentary process. <b><i>Objectives:</i></b> To evaluate the differences in the perception of renal anatomy between holographic reconstruction (HR) versus computed tomography (CT) in patients who are candidate to PN. <b><i>Methods:</i></b> CT scans of 10 consecutive patients with intermediate/high complexity renal masses (R.E.N.A.L. score &#x3e; 8) scheduled for robot-assisted PN were translated into HR. Seven raters independently described how they interpreted several anatomical details from CT and HR respectively. The exams were presented unpaired and randomly. Inter-observer agreement and evaluation time were assessed. A questionnaire inquired clinical utility of CT and HR. Inter-observer agreement was measured by the Cohen’s kappa test. Evaluation time for CT and HR was compared by the Kruskal-Wallis test, overall and per rater. Examiners answered to the questionnaire following a Likert scale. <b><i>Results:</i></b> HR showed a higher inter-observer agreement, reaching a good level (k &#x3e; 0.6) for almost all the anatomical details considered. Conversely, CT generally provided a fair or poor agreement (k &#x3c; 0.6). The evaluation time was shorter for HR (mean 1.7 vs. 3.4 min, <i>p</i> &#x3c; 0.0001). All raters declared that HR could facilitate preoperative planning before PN. <b><i>Conclusions:</i></b> HR can be useful for preoperative surgical planning before PN to ease the understanding of anatomy.
