Primary XXXX before and after renal transplantation.

@entity1 @entity8 @entity5 @entity189 @entity177 @entity3 @entity703
Three groups of @entity1 were reviewed. Primary @entity189 were found in donors kidneys of 47 recipients. In 30 instances a @entity5 was present at harvesting. When a @entity5 was removed immediately pretransplantation or early posttransplantation there were no recurrences in 14 recipients. In another two instances, a @entity5 was not removed or was incompletely excised pretransplantation and both recipients died of @entity3 . Fourteen other @entity1 received kidneys from donors in whom the opposite kidney had a @entity5 . Thirteen remained @entity5 -free and one had allograft nephrectomy for rejection 3 months posttransplantation when a @entity189 was found. In 17 recipients an allograft @entity5 was not recognized at harvesting. In 9 it was discovered at graft nephrectomy an average of 3 months posttransplantation. In a tenth @entity1 a hypoechogenic area, found on routine posttransplant ultrasonography, progressively increased in size and proved to be malignant. Another 7 @entity1 developed @entity3 from @entity703 an average of 12 months posttransplantation. Preexisting @entity189 were found in 350 recipients. Seventy-one @entity1 with incidentally discovered @entity5 had no recurrences no matter when nephrectomy was performed in relationship to transplantation. Of 279 @entity1 with symptomatic @entity703 , 70 (25%) had recurrences, 63% of which occurred in @entity1 treated < or = 2 years pretransplantation. @entity5 were found posttransplantation in 256 recipients. @entity703 were 4.6% of posttransplant @entity5 compared with 3% of @entity5 in the general population. In 222 @entity1 their own diseased kidneys were involved, in 24 @entity5 occurred in the allograft, and in 10 cases the site was not stated. Development of @entity5 seemed to be related not to the immunosuppressive therapy but to the underlying cause of @entity177 , especially analgesic @entity8 . A disproportionate number of @entity189 (15%) involved the @entity8 , most likely because of prior analgesic abuse.
