Department of Urology, Minoo City Hospital.

A 50-year-old female was admitted to our hospital with the chief complaint of right lumbago. She had undergone acupuncture for right lumbago several years earlier. Radiography revealed a linear metallic shadow in the right kidney. Computed tomographic scan revealed it to be located in the right renal parenchyma. The foreign body was extracted operatively. Including our case, 43 cases of foreign bodies in the upper urinary tract found in the Japanese literature so far are reviewed.
