Graft survival in the autosomal dominant polycystic kidney disease (ADPKD) transplant population at our center was compared to other end stage renal disease (ESRD) transplant recipients (excluding diabetics). There were 1512 adult cadaveric renal transplants carried out at our center between 1989 and 2002. After exclusions, 1372 renal grafts were included in the study. Using Kaplan-Meier methods, patient and graft survival were determined and compared between the two groups. Mean age at transplant was significantly older for the ADPKD group of patients. The age adjusted graft survival at 5 years was 79% for ADPKD patients compared to 68% in the controls. Patient survival for ADPKD patients improved from 89% at 5 years to 95% when age adjusted. Using the Cox proportional hazards models to compare ADPKD with other causes of ESRD (including recipient age and other variables) in a multifactorial model, ADPKD was significant at the 5% level (p=0.036). This study demonstrates a graft and patient survival advantage in ADPKD patients when age-matched compared to other ESRD patients.
