**4. PD versus HD and survival after renal transplantation**

In a retrospective analysis of 61 PD and 159 HD patients there were no differences in survival of patients or grafts between the two treatment groups. One year after transplantation the percentages of survivors who had received continuous ambulatory peritoneal dialysis and hemodialysis were 88% and 91% respectively, and overall graft survival was 66% and 72%, respectively [19]. Similar results were reported from 42 PD patients, either treated with CAPD for more than 26 weeks or less than 26 weeks in comparison with 55 HD patients, irrespectively if treated with azathioprine + prednisolone or cyclosporine + prednisolone [20]. A retrospective analysis of 389 patients transplanted between Juli,1974, and July 1985, also evaluated the effect of dialysis modality on transplantation and mortality rates. By correcting for the influence of different variables and using time-dependent treatment co-variables, the bias adjusted estimates of the relative risk of death did not differ significantly from one another [21]. A cohort analysis of 500 first renal transplant recipients (241 on CAPD, 259 on HD) showed identical graft and patient survival after five years. However in 37 PD patients post-transplant perito‐ neal dialysis was necessary, while 10 patients developed peritonitis [22].

In 54 patients with renal transplantation after PD compared to 48 patients after HD with an immunosuppressive regimen consisting of prednisolone, azathioprine and cyclosporine there no significant difference in patient mortality and survival or graft survival between the groups. The incidences of infections were also similar in the two groups [23].
