Classification and external resources |
Nephrogenic adenoma, also mesonephric adenoma and nephrogenic metaplasia, is a benign growth typically found in the urinary bladder.
It is thought to result from displacement and implantation of renal tubular cells, as this entity in kidney transplant recipients has been shown to be kidney donor derived.[1]
This entity should not be confused with the similar sounding metanephric adenoma.
Diagnosis
Nephrogenic adenomas are diagnosed on biopsy, by their appearance under the microscope, by pathologists.
Treatment
Even though there is no evidence of malignant potential, transurethral resection is recommended together with long-term antibiotic prophylaxis for at least one year after resection. Prolonged antibiotic therapy is suggested due to the frequent finding of UTI as an associated or causative factor.[2]
