目的探讨肾动脉狭窄患者肾功能与肾动脉狭窄的关系,并观察肾动脉支架置入的疗效.方法经肾动脉造影证实的老年肾动脉狭窄患者26例,术前和术后3个月行肾动态显像检查,以分肾肾小球滤过率为肾功能评价指标,评价肾功能与肾动脉狭窄的关系,并观察肾动脉支架置入对肾脏功能的影响.结果 26例单侧肾动脉狭窄患者,患侧肾脏与健侧肾脏的分肾肾小球滤过率分别为(18.0±9.2) ml/min和(22.9±11.1) ml/min,差异有统计学意义(t=2.118,P＜0.05).肾动脉支架置入术后3个月,患者患侧肾脏功能较术前改善,但差异无统计学意义(P＞0.05).结论肾动脉狭窄患者肾功能明显受损,但肾动脉支架置入后肾功能改善不明显.

Objective To evaluate the clinical effects of renal artery stent revascularization on renal function in elderly patients with atherosclerotic renal artery stenosis (ARAS) and investigate the relationship between renal artery stenosis (RAS) and renal function in patients with renal artery stenosis.Methods Renal angiography has demonstrated atherosclerotic RAS in the 26 patients.All patients underwent nephro-dynamic imaging before and 3 months after operation.Using single kidney glomerular filtration rate (SKGFR) for assessing renal function,the relationship between renal artery stenosis (RAS) and renal function was appraised and the effect of renal artery stent revascularization on renal function was evaluated.Results The SKGFR was lower in the affected kidney with atherosclerotic renal artery stenosis than in healthy kidney[(18.0 ± 9.2) ml/min vs.(22.9 ± 11.1) ml/ min t =2.118,P＜0.05].The renal function in the affected kidney was improved 3 months after operation than before operation,but it had no significant difference (P＞0.05).Conclusions The renal function is damaged in effected kidney in patients with atherosclerotic renal artery stenosis,and it is not significantly improved after renal artery stent revascularization.
