供肾重量和受者体表面积与移植肾功能的关系

The relationship between the allograft weight,the body surface area of the host and the early allograft function

目的 探讨供肾重量、受者体表面积及二者比值与移植肾功能的关系。 方法 对 5 3例肾移植手术患者供肾重量、受者体表面积及二者的比值与受者术后 2～ 7d血肌酐平均值进行线性相关分析。 结果 供肾重量与术后 2～ 7d血肌酐平均值无明显相关性 (P >0 .0 5 ) ;受者体表面积与术后血肌酐平均值呈正相关 (P <0 .0 1) ;供肾重量及受者体表面积的比值与术后血肌酐平均值呈负相关 (P <0 .0 1)。 结论 受者体表面积、供肾重量及受者体表面积的比值与移植肾功能的关系应引起重视 ,体表面积较大的受者应尽量选择较重的供肾相配。

Objective To investigate the relationship between the renal allograft weight,the body surface area of the host and the allograft function in the first week after transplantation. Methods The correlation of the renal allograft weight, the body surface area of the host and the mean sCr 2～7 days after transplantation was studied in 53 patients. Results Allograft weight has no obvious impact on the mean sCr in the 2～7 days after transplantation( P >0.05). The body surface area of recipients was positively correlated and the ratio of allograft weight to body surface area negatively correlated with the mean sCr in the 2～7 days after transplantation( P <0.01). Conclusions Body surface area of the recipients and the ratio of allograft weight to body surface area are important markers of the allografts function in the first week after transplantation. It is suggested that the recipients with big surface area should be transplanted with allografts of higher weight.
