**7. Own experience with PD and renal transplantation**

Because of the in part contradictory data published in the literature we analyzed our own population of renal transplant recipients with the means of a retrospective case control study. Therefore, we chose 50 consecutive peritoneal dialysis patients transplanted since 1999. For match-pair-analysis, and as control group we selected the next hemodialysis patient subse‐ quently transplanted after each PD patient. Follow-up data were available with a maximum of ten years after transplantation.

Kruskal-Wallis Test and Chi-Square-Test were calculated, with assuming a p<0.05 as signifi‐ cant, for statistical purposes.

The PD-group consisted out of 28 male and 22 female patients with a mean age of 48.7 +/- 11.5 years (HD: 31 m, 19 w, 49,8 +/-13, p=n.s.) quite reflecting the German dialysis population. With respect to time on renal replacement therapy, cytomegalo-virus-status, HLA-mismatch, proportion of living donors, age, sex and initial immunosuppression there were no differences between the groups.

Although, during follow up more less PD-patients (n=3) than HD-patients (n=8) died, this difference did not reach statistical significance. With respect to graft failure, transplant loss (n=18) occurred significantly more in HD patients (n=13) than in PD patients (n=5). Neverthe‐ less, mean serum-creatinine after 1, 2 and 5 years was not significant different between the groups. Also, delayed graft function was reported in only 4 PD patients compared to 10 HD patients (p<0.05).

To summarize, in our retrospective match-pair analysis patients on PD before renal trans‐ plantation developed less delayed graft function and had less graft loss during follow-up than patients on HD before transplantation.
