BACKGROUND AND OBJECTIVES Obesity is associated with a higher risk of nephrolithiasis. However, it is not known whether higher body fat mass or abnormal fat distribution influences stone risk independent of dietary factors. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS In this cross-sectional study, non-stone-forming men with no known kidney disease and with a wide range of body weight collec...

OBJECTIVE To identify whether stabilization of larger bladder stones would improve the efficacy of combination (ultrasonic/pneumatic) lithotripsy in a phantom bladder stone model for percutaneous cystolithopaxy. MATERIALS AND METHODS Using 1cm phantom Bego stones, a spherical model bladder was used to simulate percutaneous bladder access. A UroNet (US Endoscopy, USA) was placed alongside a Sw...

BACKGROUND Whilst still rare, the incidence of paediatric stone disease is increasing in developed countries and it is important to evaluate the aetiology. We set up a dedicated renal stone service for children combining medical and surgical expertise in 1993 and now have a large case series of children to investigate the epidemiology. METHODS A retrospective hospital note review of children ...

A male patient, born in 1990, first presented with a kidney stone when he was 10 years old, but the stone had passed spontaneously, and no further testing was done at that time. At the age of 20, he presented with a second episode of renal colic. Proteinuria and microscopic haematuria were also noticed, for which he was referred to a nephrologist. On examination, he was a lean young man with no...

To estimate the prevalence of urinary stone disease in Koreans, and to determine the inter-relationships between urinary stone disease and various epidemiological factors, 1,521 controls and 1,177 cases with urinary stones were evaluated. Of special interest in this study were: 1) proportion of past urinary stone history among controls; 1.9% 2) the point prevalence rate of urinary stones among ...

The process of olive oil extraction produces olive stone, a residue which cause considerable problems of disposal. This paper proposes and analyzes an original use of olive stone in order to improve the heat insulation performances of cement lime mortar and reduce its final density. To this purpose, the paper illustrates a set of small-scale tests, which were conducted on specimens of cement li...

It is highly difficult to pinpoint what is going through an animal's mind when it appears to solve a problem by 'insight'. Here, we searched for an information processing error during the emergence of seemingly insightful stone dropping in New Caledonian crows. We presented these birds with the platform apparatus, where a heavy object needs to be dropped down a tube and onto a platform in order...

OBJECTIVES The antioxidant capacity impairs in kidney and urinary bladder of animals with stone disease. Herbal medicine can improve the antioxidant condition of renal tissue. Cynodon dactylon (C. dactylon) is a medicinal plant with antioxidative and diuretic properties and different preparations of this plant have shown promising effects in stone disease. Assessment of the whole plant decoctio...

BACKGROUND The prevalence and incidence of kidney stone disease have increased markedly during the past several decades, and studies have demonstrated that inappropriate dietary habits are leading to more obesity and overweight (OW) in children and adults, which may be important in stone formation. Obese and OW patients share most of the same risk factors for cardiovascular morbidity, while the...
