NEPHROGENIC ADENOMA FOLLOWING KIDNEY-TRAN SPLANTATION

We report five cases of nephrogenic adenoma that arose several years a fter cadaver kidney transplantation. Cystoscopy was performed in all p atients because of gross haematuria and revealed multifocal tumorous l esions in all parts of the bladder. On admission to of hospital graft function was satisfactory in all patients, There were three female and two male patients. In all patients the therapeutic procedure consiste d of transurethral resection. Only very small lesions were fulgurated. Postoperatively an indwelling catheter was left in place for 2-4 days , and after a check on kidney parameters and immunosuppressive therapy all patients were discharged, Postoperative management consisted in c ystoscopy every 3 months in the first year and then every 6 months. Th ough the etiology of nephrogenic adenoma remains unclear, mechanical t raumatization and recurrent urinary tract infection seem to be the mos t important factors in its development.
