| pubmed-article:1509904 | pubmed:abstractText | Seven cases of inverted papilloma (IP), two located at the UUT level and five in the bladder, one associated to transitional cells carcinoma. Treatment was conservative for the whole series, and neither co-adjunctive therapy or chemoprophylaxis was applied, except for the last case; after an average follow-up of 19.8 months they all show complete remission. A discussion of urinary tract IP is suggested, studying the epidemiology, histology, pathogeny, clinical characteristics and diagnostic methods, of which endourological investigations are the most effective for a reliable diagnosis, since they allow direct visualization and biopsy sampling. Regarding the therapeutic options, the paper highlights the need for conservative surgery due to its benign biological behaviour. A strict control of the patients is necessary due to likelihood of recurrence and malignant transformation. | lld:pubmed |
