研究目的: |
本研究旨在通过前瞻性多中心临床研究,系统评估超声URM在移植肾微循环评估中的临床应用价值。研究将验证URM技术的准确性和可重复性,并以临床随访结果和/或病理为终点事件,探讨该技术在移植肾早期排斥反应的无创诊断、血管并发症实时监测以及长期移植肾功能预测等方面的应用价值。同时,研究结合超声参数、微血管组学与临床指标进行相关性分析,建立多参数临床预测模型。最终制定标准化的移植肾URM检查方案和诊断标准,为临床提供一种新型、无创、精准的移植肾随访监测工具。 |

Objectives of Study: |
The aim of this study is to systematically evaluate the clinical value of Ultra Resolution Microscopy Imaging(URM) in the assessment of microcirculation in transplanted kidneys through a prospective multicenter clinical study. The study will validate the accuracy and reproducibility of the URM technique, and investigate the value of the technique in the noninvasive diagnosis of early rejection in transplanted kidneys, real-time monitoring of vascular complications, and prediction of long-term transplanted renal function, using clinical follow-up results and/or pathology as endpoint events. Meanwhile, the study combines ultrasound parameters, microvascular histology and clinical indicators for correlation analysis to establish a multi-parameter clinical prediction model. Ultimately, a standardized transplant kidney URM examination protocol and diagnostic criteria will be developed to provide a new, noninvasive and precise transplant kidney follow-up monitoring tool for the clinic. |
