Cadaveric renal transplantation at University Hospital Kuala Lumpur: a preliminary report

Long-term survival of living donor renal transplants: A single center study

Kidney transplantation is the treatment of choice for end-stage renal disease. The aim of this study was to determine the ten-year graft survival rate of renal transplantation in patients who have been transplanted from live donors. This is a historical cohort study designed to determine the organ survival rate after kidney transplantation from live donor during a 10-year period (from March 1999 to March 2009) on 843 patients receiving kidney transplant in the transplantation center of Namazi hospital in Shiraz, Iran. Kaplan-Meier method was used to determine the survival rate, log-rank test was used to compare survival curves, and Cox proportional hazard model was used to multivariate analysis. Mean follow-up was 53.07 ± 34.61 months. Allograft survival rates at 1, 3, 5, 7, and 10 years were 98.3, 96.4, 92.5, 90.8, and 89.2%, respectively. Using Cox proportional hazard model, the age and gender of the donors along with the creatinine level of the patients at discharge were shown to have a significant influence on survival. The 10-year graft survival rate of renal transplantation from living donor in this center is 89.2%, and graft survival rate in our cohort is satisfactory and comparable with reports from large centers in the world.

Ten-year graft survival of deceased-donor kidney transplantation: a single-center experience

BACKGROUND

Kidney transplantation is the treatment of choice for end-stage renal disease that restores the patients' quality of life and reduces the morbidity and mortality rates induced by renal failure and its complications. However, after transplantation the organ and patient survival rates are important issues of interest in many centers worldwide.

SUBJECTS AND METHODS

This is a historical cohort study planned to determine the organ survival rate after kidney transplantation from deceased donor during a period of 10 years (March 1999-March 2009) in Shiraz Transplant Center, Namazi Hospital, Shiraz, Iran. We tried to clarify the probable contributory risk factors implicating in graft loss. Kaplan-Meier method was used to determine the survival rate. Log-rank test was used to compare survival curves, and Cox regression model to define the hazard ratio and for modeling of factors implicating in survival rate.

RESULTS

Mean follow-up period was 37.54 +/- 28.6 months. Allograft survival rates at 1, 3, 5, and 9 years after kidney transplantation from deceased donor (calculated by Kaplan-Meier method) was found to be 93.7, 89.1, 82.1, and 80.1%, respectively. Duration of dialysis before operation and creatinine level at discharge were showed to be the most important factors influencing survival rate of renal allograft.

CONCLUSION

Overall long-term graft survival in our cohort is satisfactory and comparable with reports from large centers in the world. Duration of dialysis before operation and creatinine level at discharge are the only independent factors that could correlate with long-term graft survival in our cohort.
