Abstract | Objective: To analyze the predictive capacity of the nephrolithometry scoring systems (GSS, STONE, CROES and S-ReSC) and stone surface regarding success and complications following percutaneous nephrolithotomy (PCNL). Methods: We studied 392 patients who had undergone PCNL in our center. Only patients with a non-contrast CT (n = 240) were finally included for analysis. The predictive capacities for success and complications of the different scoring systems were evaluated using ROC curves and their area under the curve (AUC). Results: Regarding success, the S-ReSC system had the highest predictive capacity with an AUC of 0.681 (95% CI 0.610 - 0.751), followed by the CROES with 0.667 (95% CI 0.595 - 0.738), the STONE with 0.654 (95% CI 0.579 - 0.728) and finally the GSS with 0.626 (95% CI 0.555 - 0.698). The stone surface as a single variable had an AUC of 0.641 (95% CI 0.565 - 0.718). As for complications, the S-ReSC had the highest AUC with 0.664 (95% CI 0.57 - 0.758), followed by STONE with 0.663 (95% CI 0.572 - 0.755), GSS with 0.626 (95% CI 0.555). - 0.698) and CROES with 0.614 (95% CI 0.518 - 0.7). The stone surface alone had an AUC of 0.616 (95% CI 0.522 - 0.715). Conclusion: The nephrolithometry scales analyzed show a moderate predictive capacity for success and complications in patients undergoing PCNL in our center. Moreover, stone surface as an independent variable demonstrates moderate predictive capacity for both outcomes. |
