Abstract
- PURPOSE: Lower caliceal stones treated with ESWL do fail to pass more frequently than middle or upper caliceal stones. We analyzed the results of ESWL of renal caliceal stones according to the location of calix.
MATERIALS AND METHODS
We reviewed the stone-free rate in 119 caliceal stone patients treated with 3rd generation lithotriptor, EDAP LT-02 according to the caliceal location of the stone. Location of the stones were upper calix in 30, middle calix in 30, and lower calix in 59 patients.
RESULTS
Stone-free rate was 90.0%(27/30 patients) in middle caliceal stones, 74.6%(44/59 patients) in lower caliceal stones, and 66.7%(20/30 patients) in upper caliceal stones.
CONCLUSIONS
Stone-free rate of lower caliceal stones is higher than upper caliceal stones.
