儿童肾移植46例报道

A clinical study of pediatric and adolescent renal transplantation: a report of 46 cases

目的探讨儿童肾移植的手术特点、术后并发症及免疫抑制治疗方案。方法回顾性研究1998年2月至2004年12月46例儿童肾移植患者的临床资料。观察受者及移植肾存活情况,受者生长发育情况及术后并发症。结果46例儿童肾移植后发生急性排斥反应10例,肾功能延迟恢复4例,尿漏1例,肝功能损害8例,肺部感染8例,全骨髓抑制3例,粒细胞减少2例,输尿管坏死1例,移植肾动脉狭窄1例。术后4周所有患者肾功能均恢复正常。术后1年人和移植肾存活率均为100%,3年人和移植肾存活率分别为100%和97.4%。结论肾移植是治疗儿童终末期肾病的有效手段。儿童肾移植术后急性排斥发生率高,免疫抑制治疗应根据不同个体的特点制定不同的方案。

Objective To investigate the technical features, postoperative complication and therapeutic regimen of immunosuppressant in pediatric and adolescent renal transplantation. Methods From February 1998 to December 2004, clinical data of 46 pediatric and adolescent patients who underwent renal transplantation were retrospectively analyzed to observe the patient and graft survival rate, growth and development of recipients and postoperative complication. Results Ten episodes of acute rejection （AR） were diagnosed in 46 cases. Four cases suffered delayed graft function （DGF）, one urinary leakage and 8 drug-induced hepatic injury occurred. Eight cases suffered pulmonary infection, 3 cases suffered bone marrow depression and 2 granulocytopenia. One allograft artery stenosis and one ureteral necrosis occurred. Renal functions were returned to normal in all recipients 4 weeks after operation. The 1-year patient and graft survival rates were all 100%, and the 3-year patient and graft survival rates were 100% and 97.4% respectively. Conclusions Renal transplantation is an effective treatment for pediatric and adolescent patients with end-stage renal disease. In addition to its higher AR incidence than adult, pediatric renal transplantation has especial treatment in the operation process and therapeutic regimen of immunosuppressant.
