Urinary calculi; the advice of the Health Council

The recently published advice of the Health Council of The Netherlands concerning urolithiasis can be divided in three chapters i.e. treatment, research and recent developments. The treatment with extracorporeal shockwave lithotripsy is considered the treatment of choice in 95% of patients with urolithiasis. The shockwave treatment has to be performed in centres with specialized know-how and facilities for basic and clinical research. The estimated number of extracorporeal shockwave lithotriptors in The Netherlands necessary for treatment of ca. 5400 patients per year with renal stones who are the most likely candidates for lithotripsy is at six. To prevent recurrent stone-forming in most patients metaphylactic therapy is indicated as well. At the moment lithotripsy of gallstones and treatment of kidney stones by means of lasers are in an experimental stage.

A cost utility analysis of treatment options for gallstone disease: Methodological issues and results

The techniques of cost utility analysis (CUA) were used to evaluate the treatment of gallstone disease by open and laparoscopic cholecystectomy and by extracorporeal shockwave lithotripsy (ESWL). The application of the techniques in this context raised three methodological questions which are not satisfactorily resolved in the literature. The first is whether an ex ante or ex post perspective is best adopted for the measurement of quality of life (QoL). The second is the method for converting a short term deterioration in QoL followed by full health into QALYs and the reliability of the methods available. The third is the issue of indirect costs which, in the context of a temporary disease state, cannot be easily avoided. The economic evaluation found laparoscopic cholecystectomy to be generally superior than the competitor technologies (entailing lower costs and better outcomes). However, the results were sensitive to assumptions about the perspective for measuring benefits and the inclusion of indirect costs.

Decision making on the adoption of advanced medical technology in Taiwan.

This paper discusses both the current interest in and approaches to the employment of advanced medical technology in Taiwan. It describes the formation of the national policy, including funding, reimbursement, and regulatory processes, on adopting innovative and expensive medical technologies. Using the case of extracorporeal shockwave lithotripsy (ESWL), the key players who affect organizational decision making on the adoption and diffusion of medical technology have also been analyzed. Finally, it examines some of the salient features of medical technology adoption and assessment in Taiwan, and in other countries which depend heavily upon imported advanced medical technology. It is hoped that an understanding of Taiwan's attempts to use innovative medical technology wisely while incorporating the practice of technology assessment and appropriate policies, will assist other countries with similar conditions to gain maximal benefit from technological advancement.     

Cellulite and extracorporeal Shockwave therapy (CelluShock-2009) - a Randomized Trial

Background  

Cellulite is a widespread problem involving females' buttocks and thighs based on the female specific anatomy. Given the higher number of fat cells stored in female fatty tissue in contrast to males, and the aging process of connective tissue leads to an imbalance between lipogenesis and lipolysis with subsequent large fat cells bulging the skin. In addition, microcirculatory changes have been suggested, however remain largely unknown in a controlled clinical setting. We hypothesize that the combination of extracorporeal shockwave and a daily gluteal muscle strength program is superior to the gluteal muscle strength program alone in cellulite.
