The objective of this study was to explore the donor and recipient factors related to the spectral Doppler parameters of the transplant kidney in the early posttransplantation period.
This retrospective study included 76 patients who underwent renal transplantation assessed using Doppler ultrasonography (US) on the first postoperative day. We compared spectral Doppler parameters (peak systolic velocity [PSV] and resistive index [RI]) of the segmental artery of the transplant kidney according to the type of renal transplant, level of serum creatinine (SCr) of donor prior to organ donation, and donor/recipient age.
RI was significantly higher in deceased-donor kidney transplantation (DDKT) as compared with living-donor kidney transplantation (LDKT; 0.73 ± 0.10 vs 0.66 ± 0.11; P = .007). In the DDKT recipients, multivariate analysis showed donor SCr was the only factor affecting PSV (P = .023), whereas recipient age was the only factor affecting RI (P = .035). In the LDKT recipients, multivariate analysis showed recipient age was the only factor affecting both PSV (P = .009) and RI (P = .018).
Spectral Doppler parameters in the early posttransplantation period are related to the type of renal transplant, donor renal function, and recipient age. These factors should be taken into consideration when interpreting the results of spectral Doppler US.
本研究的目的是探讨肾移植术后早期与移植肾频谱多普勒参数相关的供体和受体因素。
这项回顾性研究纳入了76例接受肾移植的患者，这些患者在术后第一天接受了多普勒超声检查。我们根据肾移植类型、器官捐献前供体的血清肌酐（SCr）水平以及供体/受体年龄，比较了移植肾段动脉的频谱多普勒参数（收缩期峰值流速[PSV]和阻力指数[RI]）。
与活体供肾移植（LDKT）相比，尸体供肾移植（DDKT）的RI显著更高（0.73±0.10对0.66±0.11；P = 0.007）。在DDKT受体中，多因素分析显示供体SCr是影响PSV的唯一因素（P = 0.023），而受体年龄是影响RI的唯一因素（P = 0.035）。在LDKT受体中，多因素分析显示受体年龄是影响PSV（P = 0.009）和RI（P = 0.018）的唯一因素。
肾移植术后早期的频谱多普勒参数与肾移植类型、供体肾功能和受体年龄有关。在解释频谱多普勒超声结果时应考虑这些因素。
