BACKGROUND: Extracorporeal shock wave lithotripsy (ESWL) is an important tool for the management of urolithiasis. The effects of shockwaves on tissues are established. The aim of this meta-analysis is to evaluate the microscopic semen characteristics of young men before and after ESWL treatment for lower ureteral calculi. METHODS: Literature searches were performed following the Cochrane guidelines. We conducted a systematic review and meta-analysis that included six trials that investigated the effects of ESWL on semen parameters, including sperm concentration, motility, and hematospermia...

K G Wang
A novel multiphase fluid-solid coupled computational framework is applied to investigate the interaction of a kidney stone immersed in liquid with a lithotripsy shock wave (LSW) and a gas bubble near the stone. The main objective is to elucidate the effects of a bubble in the shock path to the elastic and fracture behaviors of the stone. The computational framework couples a finite volume two-phase computational fluid dynamics (CFD) solver with a finite element (FE) computational solid dynamics (CSD) solver...

BACKGROUND: Percutaneous nephrolithotomy (PCNL) is recommended for treating staghorn stones or stones measuring > 20 mm. Extracorporeal shockwave lithotripsy (ESWL) or flexible ureteroscopy (URS) may be used as a complement. However, PCNL can cause trauma to the kidney parenchyma, and patients may find a noninvasive procedure, such as ESWL, to be more attractive. OBJECTIVES: The aim of this study was to evaluate the clinical efficiency of MiniJFil® stenting associated with ESWL or second-line URS for the treatment of medium-to-large kidney stones...

Background: Flexible ureteroscopy (fURS) is one of the main treatment options for urolithiasis less than 2 cm. Although fURS has no relative contraindication, some anatomical factors may need to be considered, as not all patients are suitable for the regular lithotomy position (LP). We report the case of a patient with a right iliac vascular graft that after an fURS without intraoperative incidences developed a reperfusion syndrome of the right lower limb. Case Presentation: A 46-year-old male patient was referred for treatment and follow-up in the cystinuric clinic after being found to have a 3 cm pelvic stone with a Double-J catheter in place after two failed sessions of shockwave lithotripsy...

REVIEW
Walter L Strohmaier
During the last few years, there has been relevant progress in both understanding and managing urolithiasis. Our knowledge of stone formation has changed; although the importance of urine biochemistry was questioned by several investigators years ago, the decisive role of cellular processes (induced by oxidative stress) and the renal papilla has only recently been generally accepted as the most important step in stone formation. For calcium oxalate urolithiasis, the formation of papillary calcifications plays a key role and is of prognostic relevance...

Laser induced breakdown spectroscopy and subsequent acoustic response during microplasma formation are employed to identify cancerous human breast tissues. The characteristic optical emissions identify Ca, Na, and Mg rich species in cancerous tissues compared to those of healthy ones. Furthermore, we show that the characteristic parameters of the microplasma, generated on the unhealthy tissues, are elevated. We report higher decibel audio signals emanating from laser induced microplasma and a subsequent audio blueshift for malignant tissues...

BACKGROUND: Extracorporeal shock wave therapy is effective in reducing shoulder pain and improving function in calcific supraspinatus tendinopathy. Eccentric exercise has been introduced as an effective treatment choice for Achilles tendinopathy, but poor evidence exists about its role in the treatment of rotator cuff tendinopathy. AIM: To investigate if adding a supervised eccentric training of the shoulder abductor muscles could improve the outcome of extracorporeal shock wave therapy...

For nanomaterial fabrication by laser ablation in liquid (LAL), it is very important to understand the mesoscopic process of laser interaction with materials in liquid. We proposed a method combining time-resolved shadowgraphy and optical beam deflection method to study the LAL process in both pure water and water with nanoparticles (colloids). As the laser was focused on the target in pure water, the laser energy was absorbed by the target and plasma, shockwaves and bubbles were produced, along with the generation of nanoparticles...

Cavitation plays a significant role in the efficacy of stone comminution during shockwave lithotripsy (SWL). Although cavitation on the surface of urinary stones helps to improve fragmentation, cavitation bubbles along the propagation path may shield or block subsequent shockwaves (SWs) and potentially induce collateral tissue damage. Previous in vitro work has shown that applying low-amplitude acoustic waves after each SW can force bubbles to consolidate and enhance SWL efficacy. In this study, the feasibility of applying acoustic bubble coalescence (ABC) in vivo was tested...

Ben H Chew, Dirk Lange
Open ureterolithotomy and pyelolithotomy used to be first line therapy for treating kidney and ureteral stones. With the advent of shockwave lithotripsy, open stone surgery became less prevalent, but once ureteroscopy became more prevalent, open stone surgery became all but extinct. Advances in smaller, more flexible endoscopes and improvements in intracorporeal lithotripters, ureteroscopy has become a mainstay of therapy for kidney stones. The holmium:YAG laser can be utilized through flexible instruments and fragments any stone no matter what it is composed of...

Over the past 2 decades, ureteroscopy has changed from a procedure considered second-line to shockwave lithotripsy to a commonly performed procedure for renal and ureteral stones. The increase in the use of ureteroscopy is due largely to improvements in technique and technology during this time period. Herein we review outcomes of ureteroscopy in terms of success rates, complications, and unique patient populations. This work will synthesize the data as it pertains to the practice of ureteroscopy for all endourological indications, including stone disease and management of upper tract urothelial carcinoma, as well as review state-of-the-art techniques...
