Table 1.
Outcome of beads or stone placed in a kidney calyx and exposed to ultrasonic propulsion in an attempt to relocate targeted object to the renal pelvis or ureter. Data includes number of attempts to move object, actual running time of ultrasonic propulsion probe and total length of experiment.
