Extracorporeal shock wave lithotripsy (ESWL) has had a dramatic effect on the management of urinary stones. Which of the following statement(s) are true concerning shock wave lithotripsy of urinary stones?
A. The basic principle of lithotripsy involves the generation of shock waves which are focused fluoroscopically on the calculus and are delivered to the patient who is submersed in a water bath
B. The most common complication after lithotripsy is ureteral obstruction secondary to stone fragments
C. ESWL can be associated with stone-free rates ranging between 60%-95% at six months for renal and proximal ureteral stones
D. The combination of ESWL with percutaneous nephrolithotripsy improves the results for stone clearance in patients with large or branched stones such as staghorn calculi
