[Clinico-statistical analysis of the problem of the cadaver donor in renal transplantation (clinical experience from 1945 to the present time)].

The series of cadaver donors in Bologna hospitals from 1975 to today is reviewed. All possible donors were compared with those actually utilized and the reasons that led to renunciation in a large percentage of cases are analysed. The examination shows that among the factors limiting the number of donors utilized particularly important were the criteria adopted for establishment of donor suitability, family consent and the results of support therapy of the donor's vital functions.
