Abstract

|
|
The current practice for the management of upper ureteral stones is to push the stone back into the renal pelvis before extracorporeal shock wave lithotripsy. But recent treatment modality for urinary stone is required to be less invasive and
morbid.
We evaluated 194 patients with upper ureter stones for the effectiveness of push-back. When in situ treatment was performed in 122 patients, the stone free rate at 3 months was 83.6% and the storage for complete fragmentation was 153.5. Push back
was
tried in 72 patients randomly. Out of them, 13 cases(18.6%) wee manupulated into the renal pelvis successfully and operation was required in 2 cases due to ureteral perforation. The stone free rate was 79.6% and storage for complete fragmentation
was
153.7 in push back success group. There was no significant difference between two groups.
We think that the primary treatment of choice for upper urinary stone is in situ ESWL. The treatment modality of push back is secindary choice in the case that was failed by primary in situ ESWL.
