AbstractWe studied the role of economic incentives for private providers in explaining Spain's disproportionately large number of extracorporeal shock wave lithotripters (ESWLs) and low number of linear accelerators (linacs) per million population (pmp) in comparison to other countries of the Organization for Economic Cooperation and Development (OECD). We found that the reimbursement policy for 1990 allowed an average profit per private ESWL of $732,000, but no profit for linacs. Regional per-capita income was positively correlated with ESWLs pmp in Spain (R2 = 0.49; p =.001), but not with linacs. Sixty-nine percent of ESWLs were privately held versus only 16% of linacs. To avoid these types of distortions, financial incentives should be based on a reasonable relationship between cost and charges and should be associated with the appropriateness of medical care.

Urolithiasis is currently one of the most urgent problems in the world. Every eleventh worldwide inhabitant suffers from this disease. Previously, the only way to get rid of kidney stones and the urinary tract was open surgery, which was characterized by high trauma. Over the past decades, the development of technologies has made a significant contribution to the development of new methods of urolithiasis treatment. One of these methods is extracorporeal shock wave lithotripsy (ESWL). The first lithotripter Dornier HM-1 was produced in 1980. Subsequent models have got many changes, both in terms of ergonomics and power. The researchers noticed that the efficiency of stone crushing in the Dornier HM-1 lithotripter was higher than in newer models since the lower power provided the less intensive formation of cavitation bubbles that prevent the effective transit of subsequent waves through the stone. Nowadays, a new method of remote stone crushing is being developed based on low-amplitude high-frequency technology combined with ultrasonic propulsion, which is the main difference from traditional shock-wave lithotripters. The new technology of stone crushing is called «burst wave lithotripsy» (BWL). Currently, the data have been obtained that this method is more effective in terms of crushing quality and less traumatic.
