Abstract

Background: It is said that renal transplantation lithiasis is rare. However, literature has some different frequencies in this field and most of the studies related to this issue are case reports. Also the exact effect of this complication on the graft survival rate is not clear.

Objectives: To determine the prevalence of nephrolithiasis among kidney transplant recipients and evaluate its association with the graft survival.

Methods: We conducted a retrospective study to determine the prevalence of renal stone among 574 kidney transplant patients aged ≥18 years who had undergone renal transplantation in Baqiyatallah Transplant Center between 1990 and 2010. Cox regression analysis was used to determine the effect of renal stone on the graft survival.

Results: The mean±SD follow-up time was 55±53 months. Kidney stones were diagnosed in 31 (4.4%) of all 574 kidney transplants studied. Cox regression analysis revealed that nephrolithiasis after transplantation had no significant effects on the survival of the transplanted kidney (OR 1.04, CI: 0.708-1.54).

Conclusion: For the first time, we showed that nephrolithiasis in recipients does not have a significant effect on the transplant survival.
