title: [Clinical study of ureteral polyp: three cases report and review].
abstract: Three cases of ureteral polyp are reported. The first case was an adult fibrous polyp. The second was the first report as a single, lower ureteral polyp in a child in Japan. The third was a granulomatous polyp accompanied by ureteral stones. About 130 cases of ureteral polyp have been reported in Japan. Although it has been classified into 4 to 7 histological types, the concept of ureteral polyp itself is confusing as its origin remains controversial.
