“…Ideally, the operator would also have a role in limiting the morbidity associated with shockwave exposure (Madaan et al 2007), for example by terminating the treatment when the stone has fragmented fully. In practice, the current imaging systems are largely inadequate for indicating when stone fragmentation is complete (Schmitt et al 1990;Fig. 1b), and the strategy adopted almost universally by ESWL operators is to deliver a predefined number of shockwaves (typically around 3,000).…”

“…The in-theatre clinician during the trial was only able to identify correctly seven of the 19 successful treatments (36.8 per cent sensitivity): four treatments, which at follow-up 3 weeks later proved to be unsuccessful, were considered by the in-theatre clinician to be successful, and 12 treatments, which at follow-up proved to be successful, were in theatre thought to be unsuccessful [102]. This suggests that the current imaging systems are largely inadequate for indicating when stone frag-mentation is complete [102,181]. Improving the ongoing diagnostic capabilities of the operator during the treatment could have very considerable benefits.…”

Shock wave lithotripsy (SWL) is the process of fragmentation of renal or ureteric stones by the use of repetitive shock waves generated outside the body and focused onto the stone. Following its introduction in 1980, SWL revolutionized the treatment of kidney stones by offering patients a non-invasive procedure. It is now seen as a mature technology and its use is perceived to be routine. It is noteworthy that, at the time of its introduction, there was a great effort to discover the mechanism(s) by which it works, and the type of sound field that is optimal. Although nearly three decades of subsequent research have increased the knowledge base significantly, the mechanisms are still controversial. Furthermore there is a growing body of evidence that SWL results in injury to the kidney which may have long-term side effects, such as new onset hypertension, although again there is much controversy within the field. Currently, use of lithotripsy is waning, particularly with the advent of minimally invasive ureteroscopic approaches. The goal here is to review the state of the art in SWL and to present the barriers and challenges that need to be addressed for SWL to deliver on its initial promise of a safe, effective, non-invasive treatment for kidney stones.
