U.S., Dec. 24 -- ClinicalTrials.gov registry received information related to the study (NCT07299643) titled 'Application of 3DSlicer Technology in Percutaneous Nephrolithotomy Surgery.' on Dec. 10.
Brief Summary: Objectives: Percutaneous nephrolithotomy (PCNL) has become a widely used technique for managing renal calculi. However, the rate of residual stones remains high. Accurate preoperative assessment of the individual's renal collecting system anatomy and strategic planning of access pathways are essential for improving stone-free outcomes. This study investigated whether characteristics of the target calyx can predict stone clearance through a distinct puncture calyx and developed a model to estimate the risk of residual stones in the...
