INTRODUCTION: The objective of this study was to determine whether listening to music during a session of extracorporeal shockwave lithotripsy (ESWL) improves patients' pain. MATERIAL AND METHOD: A simple, blind randomisation was undertaken of patients with kidney and ureter stones attending an ESWL session of 7,000 waves for the first time, between September and December 2014. One group was given music and the other was not. The age, gender, location of stones (kidney/ureter) were recorded and 2questionnaires: pre ESWL (questionnaire A) and postESWL (questionnaire B)...

PURPOSE OF REVIEW: This review discusses the role of molecular modifiers as inhibitors of kidney stone formation, drawing largely from in-vitro evidence while also citing relevant in-vivo studies. An emphasis is placed on physical observations of crystal growth inhibition, including mechanisms of action that focus predominantly on the literature of calcium oxalate and L-cystine. RECENT FINDINGS: The last decade has witnessed several breakthroughs in the identification of molecules with promise to curb kidney stone formation, as well as discoveries of the mechanisms by which these molecules (or combinations thereof) function as inhibitors of pathological crystal growth...

Serum concentrations of symmetric dimethylarginine (SDMA) correlate with renal function in cats and SDMA has been shown to be a more reliable and earlier marker for chronic kidney disease (CKD) compared with serum creatinine (Cr). Calcium oxalate uroliths tend to develop in mid-to-older aged cats and kidney stones may cause a reduction in renal function with increased SDMA, but normal serum Cr. The purpose of this retrospective study was to determine if cats with kidney stones had increased serum SDMA concentrations, and whether SDMA increased earlier than serum creatinine concentrations...

Melamine causes renal tubular cell injury through inflammation, fibrosis and apoptosis. While melamine effects the rise in intracellular Ca(2+) concentration ([Ca(2+)]i), reactive oxygen species (ROS) production, and pro-apoptotic pathway activation, the mechanism of upstream Ca(2+) signaling is unknown. Since melamine has some structural similarities with L-amino acids, which endogenously activates Ca(2+)-sensing receptors (CSR), we examined the effect of melamine on CSR-induced Ca(2+) signaling and apoptotic cell death...

Throughout human gestation, the placenta extrudes vast quantities of extracellular vesicles (EVs) of different sizes into the maternal circulation. While multinucleated macro-vesicles are known to become trapped in the maternal lungs and do not enter the peripheral circulation, the maternal organs and cells that smaller placental micro-vesicles interact with in vivo remains unknown. This study aimed to characterise the interaction between placental micro-vesicles and endothelial cells in vitro, and to elucidate which organs placental micro-vesicles localise to in vivo...

INTRODUCTION: Several studies have examined the link between temperature or monthly-seasonal variations and urolithiasis. The majority of these studies have demonstrated a link between higher ambient monthly temperatures and the incidence of renal colic and kidney stone disease (KSD). However a worldwide trend on this association has not been explored and we perform a systematic review to examine the effect of seasonal variations on renal colic and KSD. MATERIALS AND METHODS: A systematic review of literature over a 26-year period (1990-2017) was conducted on all studies reporting on the effect of seasonal variations and its link to KSD...

Antihypertensives are widely prescribed and could influence kidney stone risk by altering urinary calcium excretion. However, the impact of different classes of antihypertensives on kidney stone risk is unknown. To assess this impact, we conducted a retrospective, population-based cohort study using linked health administrative databases. Individuals aged >65 years who initiated one of the four antihypertensive classes (that is, angiotensin-converting enzyme inhibitors (ACEis)/angiotensin receptor blockers (ARBs), beta-blockers, calcium channel blockers or thiazide diuretics) were included...
