Abstract

Background: Renal resistive index (RRI) and estimated glomerular filtration rate (eGFR) are predictive markers for chronic kidney disease (CKD) progression. Aim: To evaluate RRI value, eGFRcr-cys and renal biomarker in nondiabetic patients with CKD stage 3 in Bangkok, Thailand. Methods: A cross-sectional analytical analysis was conducted involving nondiabetic patients with CKD stage 3, aged 35-85 years. Ultrasound was used to assess the RRI of arteries in both kidneys. Patients underwent assessments of serum and urine 24-hour. Results: Among the 61 participants (67.2% male; mean age 69.03 ± 12.59 years), the mean eGFRcr-cys was 41.63 ± 8.64 mL/min/1.73 m², and the mean RRI was 0.65 ± 0.06. Patients were categorized into three RRI groups: low (<0.65, n=35), intermediate (0.65-0.70, n=14), and high (>0.70, n=12). The high RRI group showed a mean RRI of 0.73 ± 0.05 (p < 0.01). Among those with high RRI group were significant decreased right kidney size (p<0.05) and they had a lower BMI, averaging 22.49 ± 3.48. An increase in PP (59.66 ± 13.84, p=0.04) was also significant in this group. The correlations coefficient of RRI value showed a significant positive correlation with age (p<0.05) and significant negative with BMI (p<0.05). In addition, eGFRcr-cys displayed a significant negative correlation with UAGT and 24hUP (p<0.05) and a significant while eGFRcr-cys positive correlation with both kidney size and urine iNOS(p<0.01). Conclusion: An increase in RRI is inversely linked to age, BMI, and PP. Lower eGFR is correlated with factors that cause CKD progression.

非糖尿病慢性肾病 3 期患者的肾阻指数和估计肾小球滤过率：一项横断面分析研究

背景：肾阻力指数（RRI）和估计肾小球滤过率（eGFR）是慢性肾脏病（CKD）进展的预测指标。目的：评估泰国曼谷非糖尿病 CKD 3 期患者的 RRI 值、eGFRcr-cys 和肾脏生物标志物。方法：横断面分析对年龄在 35-85 岁之间的 CKD 3 期非糖尿病患者进行横断面分析。超声波用于评估双肾动脉的 RRI。患者还接受了血清和尿液 24 小时评估。结果显示在 61 名参与者（67.2% 为男性；平均年龄为 69.03 ± 12.59 岁）中，平均 eGFRcr-cys 为 41.63 ± 8.64 mL/min/1.73 m²，平均 RRI 为 0.65 ± 0.06。患者被分为三个 RRI 组：低 RRI 组（0.70，n=12）。高 RRI 组的平均 RRI 为 0.73 ± 0.05（P < 0.01）。高 RRI 组的右肾体积明显缩小（P<0.05），体重指数较低，平均为 22.49 ± 3.48。该组的 PP 值也显著增加（59.66 ± 13.84，P=0.04）。RRI 值的相关系数与年龄呈显著正相关（P<0.05），与体重指数呈显著负相关（P<0.05）。此外，eGFRcr-cys 与 UAGT 和 24hUP 呈显著负相关（p<0.05），与肾脏大小和尿 iNOS 呈显著正相关（p<0.01）。结论RRI 的增加与年龄、体重指数和 PP 成反比。较低的 eGFR 与导致 CKD 进展的因素相关。
