Description
Shiwei Sun and five co-authors ask which scan measures best forecast kidney stone surgery results. Their 2026 study looks at retrograde intrarenal surgery, where a scope clears stones through the urinary path. Before surgery, CT scans describe each stone's size, place, and shape. Surgeons lack agreement on how to sum up total stone burden.
The team reviewed three hundred fifty-two operations from one surgical team. They tested many burden measures, from simple diameter sums to volume and spread patterns. A model using an area-based diameter, a staghorn flag, and volume spread predicted stone-free status well. A simpler diameter model came close behind. The findings may help surgeons quote odds and plan operating time before the first cut.
