To evaluate the correlation between intraabdominal pressure (IAP) measured via the bladder and renal resistive index (RRI) measured by Doppler ultrasonography (USG).
Eighty consecutive surgical patients were included into this study. Before Doppler USG evaluation, IAP was measured by a Foley catheter via the bladder. The left and right RRI, the diameters of the inferior vena cava and portal vein were measured by colored Doppler USG. Spearman correlation analysis was used to evaluate the correlation between different measurements. Intraabdominal hypertension (IAH) was defined as of IAP ≥ 12 mmHg. Significantly different variables from the univariate analysis between patients with and without IAH were entered into backward stepwise binary logistic regression analysis of IAH as the dependent variable. P values < 0.05 were accepted as statistically significant.
In total, 80 patients were included into study. In 27 patients (34%) IAP was normal and in 53 patients (66%) IAH was diagnosed. The Spearman correlation analysis of IAP and the ultrasonographic measurements revealed a strong correlation between RRI and IAP (P < 0.001). Patients with IAH were more likely to be diabetic and had abdominal incisional hernia compared with patients with normal IAP (P < 0.05). The results of the multivariate logistic regression analysis revealed right RRI as the only independent predictor of IAH (B: 57.04, S. E.: 13.7, P < 0.001).
There is a strong correlation between IAP and RRI. RRI can be an alternative, noninvasive technique for the diagnosis and follow-up of IAH after further evaluations in different patient groups.
评估经膀胱测量的腹内压（IAP）与经多普勒超声检查（USG）测量的肾阻力指数（RRI）之间的相关性。
连续纳入80例手术患者进行本研究。在进行多普勒超声检查评估前，通过Foley导管经膀胱测量IAP。用彩色多普勒超声测量左右肾阻力指数、下腔静脉和门静脉直径。采用Spearman相关性分析评估不同测量值之间的相关性。腹内高压（IAH）定义为IAP≥12 mmHg。将IAH患者和非IAH患者单因素分析中有显著差异的变量纳入以IAH为因变量的向后逐步二元逻辑回归分析。P值<0.05被认为具有统计学意义。
共纳入80例患者进行研究。27例患者（34%）IAP正常，53例患者（66%）被诊断为IAH。IAP与超声测量值的Spearman相关性分析显示，RRI与IAP之间存在强相关性（P<0.001）。与IAP正常的患者相比，IAH患者更易患糖尿病且有腹部切口疝（P<0.05）。多因素逻辑回归分析结果显示，右肾阻力指数是IAH的唯一独立预测因素（B：57.04，标准误：13.7，P<0.001）。
IAP与RRI之间存在强相关性。在对不同患者群体进行进一步评估后，RRI可作为IAH诊断和随访的一种替代性非侵入性技术。
