目得：进行荟萃分析比较肾动脉支架置入术与肾经皮腔内血管成形术（PTA）在patients with renal arterial stenosis.MATERIALS AND METHODS：研究处理肾动脉支架置入术（14篇文章; 678例患者）和肾PTA（10篇文章; 644例患者）发表到1998年8月被选中。一个随机效应模型被用来汇总data.Results：肾动脉支架置入术被证明是非常成功的，在98%的初始充分的性能和11%的主要并发症。高血压的总治愈率为20%，而高血压的改善率为49%。30%的患者肾功能改善，38%的患者肾功能稳定。随访6-29个月，再狭窄率为17%。支架置入术的技术成功率高于肾动脉PTA术，再狭窄率低于肾动脉PTA术（分别为98% vs 77%和17% vs 26%; P <0.001）。两种治疗的并发症发生率无差异。支架置入术后高血压的治愈率高于肾PTA术后，肾功能改善率低于肾PTA术后（分别为20% vs 10%和30% vs 38%; P < .001）。结论：肾动脉支架置入术在技术上优于单纯肾PTA术上级，临床上与单纯肾PTA术相当。
PURPOSE: To perform a meta-analysis of renal arterial stent placement in comparison with renal percutaneous transluminal angioplasty (PTA) in patients with renal arterial stenosis.MATERIALS AND METHODS: Studies dealing with renal arterial stent placement (14 articles; 678 patients) and renal PTA (10 articles; 644 patients) published up to August 1998 were selected. A random-effects model was used to pool the data.RESULTS: Renal arterial stent placement proved highly successful, with an initial adequate performance in 98% and major complications in 11%. The overall cure rate for hypertension was 20%, whereas hypertension was improved in 49%. Renal function improved in 30% and stabilized in 38% of patients. The restenosis rate at follow-up of 6-29 months was 17%. Stent placement had a higher technical success rate and a lower restenosis rate than did renal PTA (98% vs 77% and 17% vs 26%, respectively; P < .001). The complication rate was not different between the two treatments. The cure rate for hypertension was higher and the improvement rate for renal function was lower after stent placement than after renal PTA (20% vs 10% and 30% vs 38%, respectively; P < .001).CONCLUSION: Renal arterial stent placement is technically superior and clinically comparable to renal PTA alone.
