Abstract
We evaluated the availbility of lithoclast in ureteroscopic removal of stone retrospectivly.
We treated 62 patients(68cases) with ureteral calcui using stone basket or Swiss Lithoclast lithotriptor with the rigid dureteroscope(URS) between kecember 1993 and February 1995.
The success rates of URS were 93%(63/68), and Lithoclast use rates were 77%(52/68).
According to stone site, Lithoclast use rates were 68%(28/41) in the lower ureter, 86%(12/14) in the mid, 92%(12/13) in upper ureter respectively.
According to stone size, Lithloclast use rates were 50%(4/8) in less than 0.5cm, 75%(30/40) in 0.6-1.0cm, 89%(16/18) in 1.1-2.0cm, 100%(2/2) in above 2.0cm respectively.
The Lithoclast successfully fragmented stones.
There were 5 failures of URS due to failure in access to stone by URS(4 cases), impacted stone(1 case). Reoperation consist of URS in 2 cases, ureterolithotomy in 2 cases and nephrectomy in 1 case.
The complications of Lithoclast used URS were insignificant such as gross hematuria(3 cases), infection(2 cases), flank pain(1 case).
There were no intraoperative or long term complictions directly related to the use of this devdice.
In conculusion, Swiss lithoclast lithlotripsy significasntly contributed to improve the success rates in treatment of ureteral stone, and is a safe, effective and inexpensive device.
