摘要

引言:高血压是指持续的收缩压等于或高于140毫米汞柱或舒张压等于或超过90毫米汞柱。肾脏通过肾素-血管紧张素系统在控制高血压方面发挥着核心作用。因此,肾内动脉内膜增生的肾血管变化可能导致肾动脉阻抗增加,最终导致不可逆的高血压肾病。使用超声早期检测这些肾血管变化可以为立即干预提供机会,以预防或至少延缓不可逆的高血压肾病。目的和目的:本研究的目的是确定和比较尼日利亚卡诺Aminu Kano教学医院35-70岁血压正常和高血压成年人的肾内阻力指数(RRI)。材料和方法:对150名高血压患者和150名血压正常的对照者进行超声RRI的前瞻性病例对照研究。测量并记录两个肾脏的叶间动脉的平均RRI。数据采用SPSS 16.0软件进行分析。结果:研究参与者的年龄在35-70岁之间。年龄差异无统计学意义(P=0.88)。血压正常的对照组右侧和左侧的平均叶间动脉阻力指数(RI)分别为0.59±0.04和0.59±0.03,而高血压患者的右侧和左侧平均叶间血管阻力指数分别为0.73±0.03和0.73±0.03,两者均具有统计学意义。结论:与高血压患者相比,血压正常的参与者体内RRI较低,具有统计学意义。这些表明,高血压对肾脏有显著影响,通过早期发现和干预,可以预防不可逆的肾损伤。

A comparative ultrasonographic evaluation of intrarenal artery resistive index among hypertensive and normotensive adults in north-western Nigeria
Introduction: Hypertension is a sustained systolic blood pressure equal to or above 140 mmHg or diastolic blood pressure equal to or above 90 mmHg. The kidneys play a central role in the control of high blood pressure through the renin–angiotensin system. Thus, renovascular changes of myointimal hyperplasia in the intrarenal arteries may cause an increase in renal arterial impedance and eventually irreversible hypertensive nephropathy. The early detection of these renovascular changes using ultrasonography can provide opportunity for immediate intervention toward preventing or at least delaying the irreversible hypertensive nephropathy. Aims and Objectives: The objective of this study is to determine and compare intra-renal resistive index (RRI) in normotensive and hypertensive adults within the age range of 35–70 years at Aminu Kano Teaching Hospital, Kano, Nigeria. Materials and Methods: A prospective case–control study of intra-RRI using ultrasound in 150 hypertensive patients and 150 normotensive controls. The mean RRI of the interlobar arteries of both kidneys was measured and recorded. The data were analyzed with the aid of computer-based SPSS 16.0 software for windows. Results: The ages of the study participants ranged between 35 and 70 years. The age difference was not statistically significant (P = 0.88). The mean interlobar artery resistive index (RI) values were 0.59 ± 0.04 and 0.59 ± 0.03 on the right and left sides, respectively, in normotensive controls while those of hypertensive patients were 0.73 ± 0.03 and 0.73 ± 0.03 for the mean interlobar artery RI values on the right and left sides, respectively, and both were statistically significant. Conclusion: The intra-RRIs were lower in normotensive participants when compared with the hypertensive patients which were statistically significant. These showed that hypertension has significant effects on the kidneys, and with early detection and intervention, irreversible renal damage may be prevented.
