Abstract

INTRODUCTION

The aim of this study was to investigate the value of renal resistive index (RI) for the assessment of renal colic and to determine whether it is predictive of renal stone disease.

METHODS

A total of 70 participants were included in the research study. Group 1 comprised 43 patients with acute unilateral ureteral obstruction due to a stone disease (G1), while Group 2 consisted of seven patients with flank pain without stone disease (G2) and the control group comprised 20 healthy individuals with two normal kidneys (G3). Urinalysis, abdominal plain film radiography, conventional ultrasonography (US) and colour Doppler US were performed in all three groups. RI was calculated for all patients using Doppler US. The RI values in G1 were then compared with those in G2 and the control group.

RESULTS

There were statistically significant differences in the RI between the stone-positive group and stone-free groups (0.71 +/- 0.07 for G1; 0.69 +/- 0.06 for G2; 0.62 +/- 0.03 for G3, p-value < 0.05).

CONCLUSION

RI measurement using Doppler US can be effectively used for the assessment of renal colic patients by non-invasive means.

摘要

介绍

本研究旨在探讨肾阻力指数（RI）在评估肾绞痛中的价值，并确定其是否对肾结石病具有预测性。

方法

本研究共纳入 70 名参与者。第 1 组包括 43 名因结石病导致单侧急性输尿管梗阻的患者（G1），第 2 组包括 7 名无结石病的腰痛患者（G2），对照组包括 20 名双侧肾脏正常的健康个体（G3）。所有三组均进行了尿液分析、腹部平片放射学检查、常规超声（US）和彩色多普勒 US。对所有患者使用多普勒 US 计算 RI。然后将 G1 中的 RI 值与 G2 和对照组进行比较。
