Long-term clinical outcome of inverted urothelial papilloma including cases with focal papillary pattern: is continuous surveillance necessary?
The absence of progression of IP on long-term follow-up in this study strongly argues against the need of continuous surveillance for patients in whom (1) strict diagnostic criteria are followed, (2) a complete resection can be ascertained, and (3) no previous or concurrent urothelial malignancies are documented. In this study, the 3 patients with IP showing focal papillary architecture had a benign course, similar to the previously documented cases.
The more marked potentiation of the responses in arteries from hypertensive patients may be one of the factors influencing the patency rates.
