What is it about?
This study evaluates the role of imaging-surgery intervals (ISIs) on upper tract stone negative surgery outcomes and derives a cut-off ISI warranting updated images. Longer ISIs were associated with intra-operative disparities, especially with URETERIC stones. The derived ISI cut-offs beyond which IODs, including negative surgeries, were more likely were 9 weeks for URETERIC and 19 weeks for RENAL stones, respectively. Updating reference images that have exceeded these cut-offs could reduce the risk of disparate findings at surgery, or even the risk of a stoneless surgery, improving patient safety, efficiency, and reducing backlogs in the healthcare system.

Why is it important?
This research is important as it highlights the need for updating reference images before surgery to improve patient safety and surgical outcomes. The study found that longer intervals between imaging and surgery resulted in more disparities between the images and the actual findings during surgery, leading to unnecessary surgeries and an increased risk to patient safety. Key Takeaways: 1. The study evaluated the role of imaging-surgery intervals (ISIs) on upper tract stone negative surgery outcomes and derived a cut-off ISI warranting updated images. 2. Longer ISIs were associated with disparities between stone-related features on reference images and the surgical findings, especially with URETERIC stones. 3. The derived ROC ISI cut-offs beyond which IODs, including negative surgeries, were more likely were 9 weeks for URETERIC and 19 weeks for RENAL stones, respectively. 4. Updating reference images that have exceeded these cut-offs could potentially reduce the risk of disparate findings at surgery, or even the risk of a stoneless surgery, improving patient safety and surgical outcomes, and also improving the efficiency of theatre lists.
