title: Inverted papilloma of the ureter with subsequent invasive bladder cancer.
abstract: A 63-year old man presented with urinary frequency and urge. An IVU showed a tumour in the lower right ureter. Partial ureterectomy was done with a uretero-ureterostomy. Pathological investigation showed an inverted papilloma. Inverted papilloma of the ureter should always be considered in the differential diagnosis before major surgery is done. There is an association between inverted papilloma and urothelial carcinoma. Our patient developed an invasive bladder tumour 6 years after the operation on the inverted papilloma.
