title: Transurethral ureteroscopic retrieval of ureteric stones.
abstract: This report documents our initial experience in the transurethral retrieval of ureteric stones using the rigid ureteroscope. Ten patients are included. Half of the stones were located in the lower one-third of the ureter and half in the upper two-thirds. They varied in size from 5 to 10 mm in diameter. Seven were successfully extracted at the first attempt using stone baskets under direct vision. Of the remaining 3, one was retrieved at a second ureteroscopy, one was fragmented and subsequently passed and one required percutaneous nephroscopy for its removal from the renal pelvis. It is concluded that transurethral ureteroscopy offers a safe alternative to both open ureterolithotomy and blind manipulation.
