RESUMEN
The ancillary practice for the management of upper ureteral stones is to push the stone up the renal pelvis before extracorporeal shock wave lithotripsy(ESWL). We evaluated 103 patients with mid and upper ureteral stones for identifying the significant factors of success in push up procedure. The clinical factors of success of push up procedure may be regarded to location (upper, mid), size( 12mm>=,12mm=, 1Mo=, 1Mo 5, WBC0.05). Complications of push up were infrequent, with hematuria (30.7%), flank pain (29.7% ), and ureteral perforation (2.2% ), all of which were managed conservatively. From these data we conclude that upper ureter stones with successful clinical factors should be tried push-up into the renal pelvis before ESWL to improve the therapeutic results.
