The development of the Dornier lithotripter progressed through several prototypes, ultimately culminating in February 1980 with the first treatment of a human by shockwave lithotripsy (SWL). The production and distribution of the Dornier HM3 lithotripter began in late 1983, and SWL was approved by the U.S. Food and Drug Administration in 1984. [26]
Lithotripsy is a procedure involving the physical destruction of hardened masses like kidney stones, [1] bezoars [2] or gallstones, which may be done non-invasively. The term is derived from the Greek words meaning "breaking (or pulverizing) stones" ( litho- + τρίψω [tripso]).
He was an early advocate for the use of percutaneous nephrolithotomy in the United Kingdom, insisting that National Health Service patients and urology trainees have access to the secured Dornier HM1 Lithotripsy machine in the private sector. He was also the first to introduce extracorporeal shock wave lithotripsy to the UK. [1] [7]
Being a noninvasive method, lithotripsy, particularly extracorporeal shock wave lithotripsy (ESWL), is one of the most preferred treatment options for kidney stones. Growing awareness, technological development, and a favorable economic climate are among other factors bolstering the demand for noninvasive treatment options such as lithotripsy.
Laser lithotripsy (LL) has been evaluated against Extracorporeal Shock Wave lithotripsy (ESWL), finding both to be safe and effective. [3] [4] ESWL may be safer for small stones (<10 mm), but less effective for 10–20 mm stones. [3] A 2013 meta-analysis found LL can treat larger stones (> 2 cm) with good stone-free and complication rates. [5]
In 1994, Sawh, through his company Uroco Limited, implemented the use of the first Dornier lithotripsy machine in Trinidad, thereby expanding the treatment options available for kidney stone treatment in Trinidad. [3] In 1989, he was awarded the post of Consultant Urologist at Port-of-Spain General Hospital.
An email Dornier’s campaign shared with the Statesman showed that the county clerk’s office forwarded the campaign’s second complaint to the Secretary of State’s Office “for review ...
Electrohydraulic Lithotripsy (EHL) is a medical procedure which uses targeted shockwaves to break up kidney stones and gallstones. [1] This form of extracorporeal lithotripsy is unique in that the shockwaves are produced by a vaporization bubble expanding and collapsing repeatedly, creating a pressure wave. [ 1 ]
