This is a case of 45 year old female admitted on December 17, 1956 to Nagasaki Citizens' Hospital. She has been suffering of pyelocystitis for about a half year prior to her admission. On December 4, 1956, she complained of colic pain in the left ureteral region associated with fever sensation. The episode was followed by hematuria for four days. Left renal function decreased. X-ray examination revealed dilatation of the left renal pelvis and ureter. X-ray film could not demonstrate any concremet. At operateon a foreign body in form of grass measuring 13cm in length was detected in the lower part of the left ureter. Exact location was between the second physiological narrowing of the left ureter and the ureteral orifice. We think that she introduced it through the urethra into the bladder, during urination and bladder contraction the end of foreign body happened to be introduced into the ureter and that the sagittate character upon the stem caused it to work its way during muscular movement and peristalsis upon the ureter.
