We report a case of primary fibroepithelial polyp of the right midureter. The patient was a 41-year-old-woman, complaining of right flank pain. An excretory urogram revealed right hydronephrosis and a filling defect of the the right midureter. The filling defect was produced by a large fibroepithelial polyp that was diagnosed and removed by ureteroscopy without open surgery. Large fibroepitheli...

Ureteral fibroepithelial polyp is an unusual benign tumor of a mesodermal origin. It is very rare in infants and children, and the majority of them, excluding ones secondary to chronic irritation, were presented as a single disease without associated lesion. We report a case of multiple ureteral fibroepithelial polyps associated with ureteropelvic junction obstruction in a 5 year-old boy.

Analysis of several million expressed gene signatures (tags) revealed an increasing number of different sequences, largely exceeding that of annotated genes in mammalian genomes. Serial analysis of gene expression (SAGE) can reveal new Poly(A) RNAs transcribed from previously unrecognized chromosomal regions. However, conventional SAGE tags are too short to identify unambiguously unique sites i...
