Purpose. We seek to correlate conventional hydronephrosis (HN) grade and hydronephrosis index (HI). Methods. We examined 1207 hydronephrotic kidneys by ultrasound. HN was classified by Society of Fetal Urology guidelines. HN was then gauged using HI, a reproducible, standardized, and dimensionless measurement of renal area. We then calculated average HI for each HN grade. Results. Comparing HI to standard SFU HN grade, average HI is 89.3 for grade I; average HI is 83.9 for grade II; average HI is 73.0 for grade III; average HI is 54.6 for SFU grade IV. Conclusions. HI correlates well with SFU HN grade. The HI serves as a quantitative measure of HN. HI can be used to track HN over time. Versus conventional grading, HI may be more sensitive in defining severe (grades III and IV) HN, and in indicating resolving, stable, or worsening HN, thus providing more information for clinical decision-making and HN management.
目的。我们试图将传统的肾积水（HN）分级与肾积水指数（HI）相关联。方法。我们通过超声检查了1207例肾积水肾脏。HN根据胎儿泌尿外科学会指南进行分类。然后使用HI来评估HN，HI是一种可重复、标准化且无量纲的肾面积测量方法。然后我们计算了每个HN分级的平均HI。结果。将HI与标准的SFU HN分级进行比较，I级的平均HI为89.3；II级的平均HI为83.9；III级的平均HI为73.0；SFU IV级的平均HI为54.6。结论。HI与SFU HN分级密切相关。HI可作为HN的定量指标。HI可用于长期跟踪HN。与传统分级相比，HI在定义重度（III级和IV级）HN以及指示HN的缓解、稳定或恶化方面可能更敏感，从而为临床决策和HN管理提供更多信息。
