Abstract:
Seven cases of urothelium inverted papilloma in vesical location. Frequency in our centre is 1.4% of all urothelium tumours and mean age of patients is 63 years, 57.1% men (4 cases) and 42.9% women (3 cases). Typical clinical signs and symptoms at presentation are hacmaturia and, less frequently, a mictional irritative picture or recurrent urinary infection. It can also be accidentally found during vesico-prostate surgery performed for other cases. Evolution is benign, similar to that of transitional papilloma in our experience, and only one case of asynchronic association with a low grade vesical papillar tumour has been observed. Treatment has been endoscopic in all cases and we do not believe that chemoprophylaxis and/or immunotherapy are useful.
