In 200 consecutive patients undergoing percutaneous transluminal renal angioplasty (PTRA), a significant increase in primary success rate (P less than .02) and a concomitant decrease in complications were noted in the second 100 patients. The primary success rate increased from 93% to 97%, and the incidence of total complications fell from 20% to 13%. The incidence of complications requiring surgery fell from 5% to 2%, and the incidence of renal failure declined from 10% to 5% of the patient population. Variables that contributed to improvement in the procedure included new approaches to crossing arterial stenoses, increased use of digital imaging, less contrast material used in each case, better hydration of patients, and increased use of vascular sheaths at the puncture site.
在连续接受经皮腔内肾血管成形术（PTRA）的200例患者中，发现后100例患者的初次成功率显著提高（P＜0.02），并发症同时减少。初次成功率从93%提高到97%，总并发症发生率从20%降至13%。需要手术治疗的并发症发生率从5%降至2%，肾衰竭发生率从患者总数的10%降至5%。促成该手术改进的因素包括跨越动脉狭窄的新方法、数字成像的更多使用、每例造影剂用量减少、患者更好的水化以及穿刺部位血管鞘使用增加。
