Modified en-bloc kidney transplantation from deceased infant donor to adult recipients: a report of 4 cases / 中华器官移植杂志

ABSTRACT

Objective:To introduce a newly modified surgical approach and explore the clinical efficacy of en bloc kidney transplantation from deceased infant donors to adults.Methods:Four cases of en bloc kidney transplantation from deceased infant donor to adult were performed with a new modified surgical approach in renal transplantation and dialysis center of the Second People's Hospital of Shanxi Province from January 2017 to September 2019. All 4 cases were cardiac death donors. There were 3 males and 1 female donors, aged (54 ± 22.69) d and weighing (5.6 ± 0.79) kg. There were 1 male and 3 female recipients, aged (41.5 ± 5.97) years and weighing (45 ± 3.56) kg. For lowering operative difficulties and preventing hemodynamic disturbances, bilateral kidneys were sutured and fixed during trimming. Then end-to-side anastomosis was performed between donor kidney abdominal aortic valve and recipient external iliac artery and between donor renal inferior vena cava valve and recipient external iliac vein.Results:All operations were successful without vascular or urinary complication. The average duration of donor kidney repair was 20 min and the average duration of transplantation 68.75 min. The functions of transplanted kidney recovered well during a follow-up period of 12 months. The long-term survivals of recipient and transplanted kidney were satisfactory.Conclusions:The newly modified surgical approach of en bloc kidney transplantation from deceased infant donor to adult has optimized operative handling. With a higher success rate, vascular complications are lowered. A wider popularization is recommended.
