Can preoperative planning using IRIS™ three-dimensional anatomical virtual models predict operative findings during robot-assisted partial nephrectomy?

Objective: To evaluate the predictive validity of IRIS™ (Intuitive Surgical®, Sunnyvale, CA, USA) as a planning tool for robot-assisted partial nephrectomy (RAPN) by assessing the degree of overlap with intraoperative execution.

Methods: Thirty-one patients scheduled for RAPN by four experienced urologists were enrolled in a prospective study. Prior to surgery, urologists reviewed the IRIS™ three-dimensional model on an iphone Operating System (iOS) app and completed a questionnaire outlining their surgical plan including surgical approach, and ischemia technique as well as confidence in executing this plan.

Role of multi-parametric magnetic resonance imaging fusion biopsy in active surveillance of prostate cancer: a systematic review.

Background: Our goal is to review current literature regarding the role of multi-parametric magnetic resonance imaging (mpMRI) in the active surveillance (AS) of prostate cancer (PCa) and identify trends in rate of reclassification of risk category, performance of fusion biopsy (FB) systematic biopsy (SB), and progression-free survival.

Methods: We performed a comprehensive literature search in PubMed and identified 121 articles. A narrative summary was performed.

Utilizing head-mounted eye trackers to analyze patterns and decision-making strategies of 3D virtual modelling platform (IRIS) during preoperative planning for renal cancer surgeries.

Purpose: IRIS provides interactive, 3D anatomical visualizations of renal anatomy for pre-operative planning that can be manipulated by altering transparency, rotating, zooming, panning, and overlaying the CT scan. Our objective was to analyze how eye tracking metrics and utilization patterns differ between preoperative surgical planning of renal masses using IRIS and CT scans.

Methods: Seven surgeons randomly reviewed IRIS and CT images of 9 patients with renal masses [5 high complexity (RENAL score ≥ 8), 4 low complexity (≤ 7)].

Firearm Ownership, Defensive Gun Usage, and Support for Gun Control: Does Knowledge Matter?

Unlabelled: Recent incidents of gun violence have raised questions about public access to "military-style" firearms and the need for more-restrictive forms of gun control. Proponents of more-restrictive forms of gun regulation argue that such measures will help combat the disproportionately high rates of gun crime in the United States. Opponents believe that such measures infringe upon constitutional rights and hinder law-abiding citizens' abilities to adequately defend themselves.
