Lidocaine jelly push-back of ureteral stones.
Pushing ureteral stones into the renal pelvis significantly facilitates extracorporeal shock-wave lithotripsy or percutaneous nephrolithotripsy. The technique is simple and less hazardous than mechanically relocating the stone with a wire or a catheter. It requires retrograde injection of 2% lidocaine jelly into the ureter via an 8-10F catheter placed just distal to the stone. Of forty-seven ureteral stones (24 upper, 19 mid, and 4 lower ureter), 44 were relocated successfully.
