目的观察经皮腔内肾血管成形术(PTRA)治疗肾动脉狭窄的临床疗效。方法选取2013年11月—2016年11月随州市中心医院泌尿外科收治的肾动脉狭窄患者124例,均行PTRA。比较所有患者手术前后肾动脉多普勒超声检查结果 [肾动脉狭窄处峰值流速(PSV)、肾内收缩早期加速时间(AT)、收缩早期加速度(AC)、阻力指数(RI)、频谱波形]、血压及血肌酐水平。结果所有患者术后PSV、AT、RI及频谱波形发生率低于术前,AC高于术前(P<0.05)。所有患者术后收缩压、舒张压及血肌酐水平低于术前(P<0.05)。结论 PTRA可有效改善肾动脉狭窄患者血压和肾功能,且安全可靠。
Objective To observe the clinical efficacy of percutaneous transluminal renal angioplasty (PTRA) in the treatment of renal artery stenosis. Methods 124 patients with renal artery stenosis admitted in Department of Urology, Suizhou Central Hospital from November 2013 to November 2016 were selected and underwent PTRA. Preoperative and postoperative renal artery Doppler ultrasonography (PSV, AT, AC, RI, and spectral waveforms) of all patients were compared before and after surgery. , Blood pressure and serum creatinine level. Results The incidences of postoperative PSV, AT, RI and spectral waveforms in all patients were lower than those before operation, and the AC was higher than that before operation (P <0.05). Postoperative systolic blood pressure, diastolic blood pressure and serum creatinine were lower in all patients than those before operation (P <0.05). Conclusion PTRA can effectively improve the blood pressure and renal function in patients with renal artery stenosis and is safe and reliable.
