In Vitro Comparison between HM‐3 and MODULARIS Lithotripters

Shockwave lithotripsy (SWL) is currently the preferred method of treatment for renal calculi < 10 mm in size. Dornier introduced the electrohydraulic HM‐3 in 1983, which has become the “gold standard” for SWL. Since then other types of lithotripters (electromagnetic and piezoelectric) have been developed. We compared the third‐generation electromagnetic shockwave lithotripter Siemens MODULARIS to the HM‐3 in vitro assessing acoustic measurement and stone comminution in a holder. Similar results were encountered.
