A case of ectopic ureter complicated with ipsilateral renal hypoplasia and ureter stone was reported. The patient was a 6-year-old girl with complaints of urinary incontinence and persistent pyuria. Urolo-gical studies revealed that the right ureter ectopically opened into the urethra and the stone existed in lower ureter which dilatated cystically. The anatomical anomaly like this and persistent urinary tract infection due to Proteus were considered the predisposing factors for stone formation. There are 497cases of ureteral ectopia in Japanese literature by June 1979.
