[Pediatric renal transplantation: Experience in Lausanne 1971 to 1998].

AIMS OF THE STUDY: Analysis of indications and results of paediatric renal transplantation in a single centre, before and after the introduction of cyclosporine A (CSA). METHODS: Historical retrospective study. RESULTS: 19 transplantations were performed in 14 patients (5 second grafts) between 1971 and 1987 (group I). 13 patients were transplanted between 1988 and 1998 (no second transplant) (group II). In group II, all the patients had immunosuppression with CSA, but none in group I. Group II, with CSA, showed better renal survival than patients without CSA. In group I, obstructive uropathies (posterior urethral valves, pyelo-ureteral junction stenosis, vesico-ureteral reflux) represent a common cause (35%) of terminal chronic renal failure (TCRF), whereas in group II they represent only 15% of the causes and chronic glomerulonephritis is the most common cause (69%) of TCRF. Acute and chronic graft rejections were the cause of 9 and 1 graft losses in group I and II respectively. Living related donors account for 14% of all renal transplantations in group I and 46% in group II. CONCLUSIONS: The incidence of paediatric patients referred to Lausanne for TCRF is stable. We have observed a constant and steady decrease in obstructive uropathies leading to TCRF and renal transplantations, whereas glomerulonephritis are increasingly frequent. Graft survival has much improved since the introduction of cyclosporine A, without an increase in morbidity. In carefully selected cases, intrafamilial renal transplantation provides good results and helps to shorten the time spent on dialysis.
