Transplant nephrectomy and simultaneous second graft retransplantation
Israel Journal of Medical Sciences
|January 1, 1976
Summary
Simultaneous kidney transplant nephrectomy and retransplantation offers a viable option for patients with rejected kidney allografts, with comparable success rates and risks to primary transplants. Presensitization from the first transplant increases hyperacute rejection risk in subsequent procedures.
Area of Science:
- Nephrology
- Transplantation Immunology
- Surgical Procedures
Background:
- Kidney allograft rejection necessitates alternative treatment strategies.
- Transplant nephrectomy followed by retransplantation is an established approach.
- Simultaneous procedures offer a potential solution for managing rejected kidney transplants.
Purpose of the Study:
- To evaluate the safety and efficacy of simultaneous transplant nephrectomy and retransplantation.
- To identify factors influencing the success of second kidney transplants.
- To understand the rejection patterns in retransplanted patients.
Main Methods:
- Retrospective analysis of 29 patients undergoing simultaneous transplant nephrectomy and retransplantation.
- Comparison of outcomes with primary kidney transplantation.
- Analysis of patient data, including dialysis history, graft survival, and kidney source.
Main Results:
- The simultaneous procedure demonstrated comparable success rates and risks to primary kidney transplants.
- No significant correlation found between patient/graft factors and second graft survival.
- Hyperacute or accelerated rejection accounted for 75% of second graft failures, likely due to presensitization.
Conclusions:
- Simultaneous transplant nephrectomy and retransplantation is a safe and effective option for rejected kidney allografts.
- Presensitization significantly contributes to hyperacute rejection in retransplanted patients.
- Limited cadaver kidney availability hindered the widespread application of this procedure.
