Sex differences in renal transplantation in Canada

To determine if a patient's sex influences access to renal transplantation in Canada, transplant recipient data for first cadaveric unrelated renal transplants were obtained from the Canadian Organ Replacement Register (CORR) for the period 1985-1992. There were 4683 first unrelated cadaveric transplant recipients during this time. Differences in the proportion of men and women registered with CORR who received a renal transplant were analyzed. In Canada between 1985 and 1992, 25% of males 40 years and older on dialysis received renal transplants compared with 18% of females (p < 0.0001, RR 1.54, 95% CI 1.40-1.67). There was no difference in the rates of transplants in males and females who were under 40 years of age. Adjusting for panel-reactive antibody data did not change the significance of the difference in transplant rates between the sexes. In Canada from 1985 to 1992, male patients with end-stage renal disease received proportionately more transplants than females.
