Push and smash increases success rates in treatment of ureteric calculi by ESWL

During a 3-year period 105 patients underwent attempted retrograde manipulation for ureteric calculi into the renal pelvis prior to extracorporeal shock wave lithotripsy (ESWL). The success rate of this group was compared to 93 patients receiving ESWL of ureteric calculi in situ. The method of retrograde manipulation was recorded prospectively. Retrograde flushing with a 5 F Tiemann ureteral catheter was performed after coating the proximal ureter and renal pelvis with a mixture of saline and lidocaine gel. Success rate of calculi push was 91.4%. Mean number of ESWL treatments in this group of patients was 1.4, compared to 2.1 in patients with in situ treatment. Reposition of ureteric calculi prior to ESWL treatment increases successful initial treatment and can be performed easily.
