This study was designed to investigate the variability of renal ultrasound measurements, focusing on the impact of physician experience and patient position. : Since decreased kidney length is considered an indicator for chronic renal disease, understanding measurement repeatability and reproducibility is crucial for establishing effective diagnostic guidelines. : Fifty healthy young adults underwent renal ultrasound scans performed by three examiners with varying levels of experience (12 years, 5 years, and 4 weeks). Renal length was measured at the level of the hilum in three patient positions: supine, lateral decubitus, and prone, using a 2-6 MHz convex probe (GE Logiq S8). This study found that examiner experience significantly affected the results of sonographic measurements. However, the Interclass Correlation Coefficient analysis for all examiners demonstrated good reliability in most positions, with the highest values observed for the prone position. Measurements in the lateral decubitus position showed highest values, especially for the most experience examiner. The less experienced sonographers produced more variable results. Standardized patient positioning improves the accuracy and reproducibility of renal ultrasound measurements. The prone position offers a balance of reliability and practicality, especially for less experienced operators.
本研究旨在调查肾脏超声测量的变异性，重点关注医生经验和患者体位的影响。由于肾脏长度减小被认为是慢性肾病的一个指标，了解测量的重复性和再现性对于制定有效的诊断指南至关重要。五十名健康的年轻成年人接受了由三名经验水平不同（12年、5年和4周）的检查者进行的肾脏超声扫描。使用2-6MHz凸阵探头（GE Logiq S8），在三个患者体位（仰卧位、侧卧位和俯卧位）下于肾门水平测量肾脏长度。本研究发现，检查者的经验显著影响超声测量结果。然而，对所有检查者的组内相关系数分析表明，在大多数体位下可靠性良好，俯卧位观察到的数值最高。侧卧位测量显示数值最高，尤其是对于经验最丰富的检查者。经验较少的超声检查人员产生的结果更具变异性。标准化的患者体位可提高肾脏超声测量的准确性和再现性。俯卧位在可靠性和实用性之间提供了平衡，尤其对于经验较少的操作人员。
