尿管の異所性骨形成の1例

Abstract

A 62-year-old woman was first seen in 1976 with complaints of left flank pain and fever attack. There was no abnormal calcification in KUB and a moderate stenosis at left middle ureter was observed in DIP and retrograde pyelography. At the operation we recognized that this ureteral stenosis was due to a stone-like substance attached to the ureteral wall, which was pathologically estimated to be an ectopic bone formation in a ureter. This abnormality was not reported in the literature except Klinger's case. Some discussion was made about the etiology of ossification in a ureter.
