研究目的: |
1.主要目的 开发并验证基于术前CT的深度学习模型,预测ESWL治疗响应分级 (FER(结石碎片化率)将通过比较治疗前后特定时间点的标准化CT扫描中结石总体积变化进行量化评估。研究目的不仅在于开发模型,更在于全面评估其判别、校准和临床实用性。 2.次要目的 (1)探索影像特征与疼痛缓解(Izbicki评分降低>50%)的关联。 (2)评估模型对内外分泌功能变化(通过粪弹性蛋白酶E1水平、HbA1c变化、以及胰酶替代和降糖药物需求变化进行评估)的预测价值。 (3)分析治疗效应异质性,识别最适合ESWL的患者亚群。 (4)建立基于预测模型的临床决策支持系统,初步前瞻性评估其对临床决策的潜在影响。 |

Objectives of Study: |
1. Primary Objective Develop and validate a deep learning model based on preoperative CT scans to predict the response grading of ESWL treatment (FER, fragmentation rate, will be quantitatively assessed by comparing changes in stone volume at specified time points on standardized CT scans before and after treatment). The study aims not only to develop the model but also to comprehensively evaluate its discrimination, calibration, and clinical utility. 2. Secondary Objectives (1) Explore the association between imaging features and pain relief (defined as a reduction of more than 50% in the Izbicki score). (2) Assess the model's predictive value for changes in endocrine and exocrine function (evaluated through fecal elastase-1 levels, changes in HbA1c, and variations in the need for pancreatic enzyme replacement and hypoglycemic medications). (3) Analyze heterogeneity of treatment effects to identify patient subgroups most suitable for ESWL. (4) Establish a clinical decision support system based on the predictive model and preliminarily prospectively evaluate its potential impact on clinical decision-making. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
数据采集:首先,创建一个标准化的病例记录表,包含所有需要收集的信息字段,如患者的年龄、性别等基本信息以及临床病史等。接着,为每位患者创建一个唯一的标识符,以便在整个数据集中唯一标识每个病例。最后,将所需的信息字段记录于excel表格并进行双人核对; 数据管理:有关受试者身份相关的所有信息资料均予以保密,相关资料在相关法律和/或法规允许的范围之外不对外公开。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data Collection: First, a standardized case record form is created containing all the fields of information to be collected, such as basic information about the patient's age and gender, as well as clinical history. Next, a unique identifier was created for each patient to uniquely identify each case throughout the dataset. Finally, the required information fields were recorded in an excel sheet and double-checked; |
