The increasing global prevalence of nephrolithiasis continues to burden the healthcare delivery systems of industrialized nations and exact a disproportionate humanitarian toll on populations of the developing world (1). In the United States alone, the prevalence of nephrolithiasis is nearly twice the rate reported in the 1960s (2-5). The subsequent rise in(More)
PURPOSE Calyceal selection for percutaneous renal access is critical for safe, effective performance of percutaneous nephrolithotomy. Available anatomical evidence is contradictory and incomplete. We present detailed renal calyceal anatomy obtained from in vivo 3-dimentional computerized tomography renderings. MATERIALS AND METHODS A total of 60(More)
Obesity is a strong risk factor for nephrolithiasis, but the role of physical activity and caloric intake remains poorly understood. We evaluated this relationship in 84,225 women with no history of stones as part of the Women's Health Initiative Observational Study, a longitudinal, prospective cohort of postmenopausal women enrolled from 1993 to 1998 with(More)
The pathophysiology of the various forms of urinary stone disease remains a complex topic. Epidemiologic research and the study of urine and serum chemistries have created an abundance of data to help drive the formulation of pathophysiologic theories. This article addresses the associations of urinary stone disease with hypertension, cardiovascular(More)
Among the challenges facing nurses in acute care facilities are duplicate documentation, complex rules for coordinating care, and pressure to accelerate patient discharge. Christiana Care, a two-hospital, 900-bed health system in Delaware, redesigned its nursing admissions process to address these issues and provide a centralized source of assessment(More)
A 43-year-old patient has just left the office. Her primary care physician had dutifully evaluated her recent complaint of vague abdominal pain with an abdominal ultrasound. The multiple, small, punctate hyperechoic lesions in the kidney were deemed concerning for renal calculi and an abdominal computed tomography (CT) scan was ordered to better delineate(More)
OBJECTIVES To engage with the experiential phenomena of men's self-harm, to get a sense of its 'feel', its character, and to relate these things in a useful and authentic way. DESIGN Qualitative in-depth interview study with design input from service users' groups. METHOD Hermeneutic phenomenology. Two interviews with each of four participants in their(More)

PURPOSE Common methods of commercial urolithiasis analysis, such as light microscopy and Fourier transform infrared spectroscopy, provide limited or no information on the molecular composition of stones, which is vital when studying early stone pathogenesis. We used synchrotron radiation based microfocused x-ray fluorescence, x-ray absorption and x-ray(More)
PURPOSE The limitations imposed by human clinical studies and mammalian models of nephrolithiasis have hampered the development of effective medical treatments and preventive measures for decades. The simple but elegant Drosophila melanogaster is emerging as a powerful translational model of human disease, including nephrolithiasis. It may provide important(More)
