| 目的 应用彩色多普勒超声检测早期移植肾段动脉血流阻力指数(RI),并探讨其对远期预后的影响。方法 对299例肾移植术后患者资料进行回顾,门诊随访至少3个月。根据RI将入选病例分为A组(RI≥0.8)、B组(RI<0.8)。结果 与B组相比较,A组病例在接受肾移植手术时的年龄和供肾者年龄更大(P<0.001),术前存在更严重蛋白尿(P=0.01)。移植肾RI与供肾者年龄、受肾者年龄及24 h尿蛋白量之间存在相关关系(P均<0.05)。RI是较其他因素更为可靠的预测指标。结论 彩色多普勒超声检测早期移植肾动脉血流RI可对其远期移植肾存活进行预测。 |

| Objective To investigate the value of color Doppler ultrasound in measurement of renal artery resistance index after kidney transplantation and its influence on long-term prognosis. Methods Data of 299 patients after kidney transplantation were retrospectively analyzed, and the patients were followed more than 3 months. Then the patients were divided into two groups according to RI value, those in group A having higher RI (≥0.8), while in group B having RI lower (<0.8). Results Compared with group B, patients in group A were older at the time of transplant (P<0.001), the donor age was also older (P<0.001), proteinuria before kidney transplantation in group A was more severe than in group B (P=0.01). RI directly correlated with the recipient age, donor age and daily proteinuria (all P<0.05).As a prediction index of long-term prognosis after kidney transplantation, RI was more reliable. Conclusion Early measurement of RI after kidney transplantation with color Doppler ultrasound helps to predict long-term graft survival. |
