目的 :探讨肾移植术后移植肾的代偿性增生情况。方法 :前瞻性地观察了 43例肾移植受者 ,术前记录受者体重及供肾重量 ,并于术后第 5天、 1个月、 3个月和半年时 ,常规超声检查测量移植的长、宽、厚以及肾皮质和实质的厚度。结果 :术后 3个月时 ,移植肾体积 (185 .6 8± 41.10 ) ml较术后 5天 (15 1.81± 32 .97) ml和 1个月 (146 .79± 2 8.81) ml时明显增大 ,肾脏增生的部位主要在肾皮质 ,手术后半年 ,肾脏增生已达稳定水平。其中年轻肾移植受者 (198.5 4± 2 6 .18) ml较年长者 (173.84± 2 5 .5 9) ml移植肾增生明显 ;相对重量较小的受者移植肾增生更迅速。结论 :移植肾和肾切除患者的留存肾一样 ,都可出现代偿性增生 ,都与年龄因素有关。移植肾的代偿性增生受供肾和受者两方面因素的影响
Objective: To investigate the compensatory hyperplasia of renal allograft after renal transplantation. Methods: Forty-three kidney transplant recipients were prospectively studied. Body weight and donor weight were recorded preoperatively. Conventional sonography was performed on the 5th, 1th, 3rd and 6th months after transplantation Length, width, thickness and renal cortex and the actual thickness. Results: At 3 months after operation, the volume of renal allograft (185.6 ± 41.10) ml was significantly higher than that at 5 days (15 1.81 ± 32.97) ml and 1 month (146.79 ± 2 8.81) ml Increased, the main site of renal hyperplasia in the renal cortex, six months after surgery, kidney hyperplasia has reached a stable level. Among them, the number of young kidney transplant recipients (198.5 4 ± 2 6.18) ml was significantly higher than that of the elderly (173.84 ± 2.55 5.9 ml), while the transplant recipients with relatively smaller weight were proliferated more rapidly. CONCLUSION: Compensatory hyperplasia can occur in allograft and nephrectomized patients, all of which are related to age. Compensatory hyperplasia of the kidney graft is influenced by both the donor and the recipient
