title: Nephrogenic adenoma of the bladder in renal transplant recipients: a report of 9 cases with assessment of deoxyribonucleic acid ploidy and long-term followup.
abstract: OBJECTIVE
  We evaluated the outcome of nephrogenic adenoma, a benign tumor rarely encountered in renal transplant recipients.
  
  
  METHODS
  Between 1985 and 1993, 9 renal transplant recipients with a nephrogenic bladder adenoma removed by endoscopic resection were followed for 24 to 88 months (mean 40). Tumor deoxyribonucleic acid ploidy was assessed by flow cytometry at diagnosis and/or relapse.
  
  
  RESULTS
  The relapse rate was 88%. The tumors were diploid and of low proliferating potential, and showed no malignant transformation.
  
  
  CONCLUSIONS
  Our study confirms the lack of premalignant potential of nephrogenic adenomas. However, since transplant recipients might be at increased risk for bladder cancer, they should be followed closely.
