Purpose:
Nephrogenic adenoa is a rare, benign disease of the urinary tract, usually as a response to chronic irritation or trauma. We report our clinical experience and review the literature.
Materials and Methods:
From 2005 to 2015, 6 patients were diagnosed to nephrogenic adenoma at urinary bladder after transurethral resection (TUR). We retrospective reviewed and analyzed the characteristic of these tumors, presenting symptoms, and prognosis.
Results:
There were 4 female and 2 male genders. Aged between 32 to 72 (mean 54) year-old. All patients have granulation or nodular lesion at bladder. Four patients presented with repeat hematuria, five patients had recurrent urinary tract infection. Three patients were associated with urothelial carcinoma. Two patients had long term Foley indwelling. Four patients persisted hematuria after TUR, consider recurrent disease. No mortality noted.
Conclusion:
Nephrogenic adenoma is a rare and benign metaplastic lesion occurring in the urothelium. Recurrence rate is relatively high, so careful and long term regular follow-up is necessary.
