“…Raskolnikov et al describes a new ultrasound technique that takes this even further, with promising results in vitro. The new technology, utilising ultrasound technology and named burst wave lithotripsy (BWL), utilises a prolonged burst of consecutive, low amplitude ultrasound pulses rather than a single high amplitude shock wave produced in ESWL [79][80][81]. ESWL pulses lead to a focused fracture point, with resulting unsatisfactory stone fragmentation into large fragments that are then subsequently more difficult to break up with successive pulse waves.…”

This chapter explores the diagnosis as well as various methods for stone clearance and recent advancements in each of the avenues, so as to provide the avid reader an understanding of the basis of each intervention and new exciting technology that lay on the horizon. Each section is further subdivided such that it would be easy for readers to search and look up relevant information at a glance without having to read through the entirety of the chapter. Firstly, diagnosis of renal calculi is explored, as renal tract pain can mimic a variety of abdomino-pelvic conditions and cause the same constellation of symptoms. Evidence based investigation modalities are discussed. Subsequently, management of renal tract calculi are divided into conservative management with analgesia and medical expulsion therapy, extracorporeal shock wave lithotripsy, ureteropyeloscopy and laser lithotripsy, as well as percutaneous nephrolithotomy. The different stone size, composition, location and patient factors have all contributed to the different surgical options as detailed above. Each section end with a discussion of new and exciting innovations in each of the areas that may lead to even more efficient and safer interventions for the Urology of the future.

“…Burst wave lithotripsy has been shown to deliver more energy, more quickly, by delivering at a higher pulse repetition frequency (PFR). It offers more therapeutic advantages such as the fact it may be performed in an ambulatory setting with a handheld device and requires less sedation (Maxwell et al 2019, Raskolnikov et al 2022). As described earlier, stone position is a major factor in patient selection.…”

“…As described earlier, stone position is a major factor in patient selection. Ultrasound propulsion of the stone, as first described by Shah et al (2010), has shown to use transcutaneous ultrasound waves that produce a radiation force allowing repositioning for stones making them more amenable to ESWL (Raskolnikov et al 2022). Dual shockwave lithotripters are also being developed to try and minimise cavitation experiences in current lithotripsy by introducing two rapidly successive shock waves (Raskolnikov et al 2022).…”

Throughout history, many innovations have contributed to the development of modern urological surgery, improving patient outcomes and expanding the range of treatment options available to patients. This article explores five key historical innovations that have shaped modern urological surgery: External shockwave lithotripsy, transurethral resection of prostate, cystoscope, perioperative prostate-specific antigen and robotic surgery. The selection of innovations for inclusion in this article was meticulously determined through expert consensus and an extensive literature review. We will review the development, impact and significance of each innovation, highlighting their contributions to the field of urological surgery and their ongoing relevance in contemporary and perioperative practice.

“…It has been proposed that cumulative strain develops over the 1000–4000 shock waves required to fragment a stone, which may be a potential mechanism underlying the fatigue and rupture of blood vessels and tubules in the kidney, which is a common side-effect [ 45 , 46 ]. Burst wave lithotripsy is a related emerging technology that employs lower amplitude bursts of ultrasound (100 s of kHz centre frequency), which are used to fragment or push a kidney stone [ 47 ]. The bursts of ultrasound are sent at 10–40 Hz repetition frequencies and also have the potential to deform and damage tissue [ 48 ].…”

Agarose gels are often used as a tissue mimic. The goal of this work was to determine the appropriate agarose concentrations that result in mechanical properties that match three different porcine organs. Strain tests were carried out with an amplitude varying from 0.01% to 10% at a frequency of 1 Hz on a range of agarose concentrations and porcine organs. Frequency sweep tests were performed from 0.1 Hz to a maximum of 9.5 Hz at a shear strain amplitude of 0.1% for agarose and porcine organs. In agarose samples, the effect of pre-compression of the samples up to 10% axial strain was considered during frequency sweep tests. The experimental measurements from agarose samples were fit to a fractional order viscoelastic (springpot) model. The model was then used to predict stress relaxation in response to a step strain of 0.1%. The prediction was compared to experimental relaxation data, and the results agreed within 12%. The agarose concentrations (by mass) that gave the best fit were 0.25% for the liver, 0.3% for the kidney, and 0.4% for the heart. At a frequency of 0.1 Hz and a shear strain of 0.1%, the agarose concentrations that best matched the shear storage modulus of the porcine organs were 0.4% agarose for the heart, 0.3% agarose for the kidney, and 0.25% agarose for the liver.
