Treatment of upper ureteral stone with ESWL: push back effect / 대한비뇨기과학회지

ABSTRACT

Extracorporeal shock wave lithotripsy (ESWL) was performed in 122 patients with upper ureteral calculi managed by 3 different techniques ; ESWL in situ. after push back and after placement of push back ureteral catheter below the stone in patients of failure to push back. To investigate the push back effect for upper ureteral stone, we reviewed 3 different treatment modalities. Of 122 patients push back was performed in 54 patients, which was successful in 27 patients (50%). The success rate of ESWL and the number of total average shock waves were 100%, 1667 waves in successful push back patients. 98.5%. 3007 waves in situ treatment and 88.9%, 4133 waves in patients of failure to push back. Complications of push back were infrequent, with the most common being ureteral perforation in 2 patients. all of which were managed conservatively. Push back of upper ureteral calculi improved success rate of ESWL and reduced significantly the number of average shock Waves.
