PURPOSE The occurrence of brushite stones has increased during recent years. However, the pathogenic factors driving the development of brushite stones remain unclear. METHODS Twenty-eight brushite stone formers and 28 age-, sex- and BMI-matched healthy individuals were enrolled in this case-control study. Anthropometric, clinical, 24 h urinary parameters and dietary intake from 7-day weighed...

BACKGROUND The metabolic syndrome (MS) is associated with increased prevalence of kidney stones, yet the specific stone type remains largely unknown. This study was conducted to assess whether risk factors associated with calcium nephrolithiasis increase with individual characteristics of the MS. METHODS A retrospective analysis was performed in 109 non-stone-forming subjects and 128 recurren...

INTRODUCTION Most bladder stones develop in patients with bladder outlet obstruction. Intravesical stone formation after surgery outside the urinary bladder is rare. CASE PRESENTATION A 54-year-old Taiwanese woman with lower urinary tract symptoms following a hysterectomy 14 years ago presented to our hospital.

PURPOSE Recent studies have suggested that renal phosphate leakage and the associated phosphaturia are significant underlying causes of calcium urolithiasis. The aims of this study were to assess whether phosphaturia relates to urinary metabolic abnormalities and recurrent stone formation. MATERIALS AND METHODS A database of patient histories and urine chemistries was analyzed for 1,068 conse...

The etiology of stone disease remains unknown despite the major technological advances in the treatment of urinary calculi. Clinically, urologists have relied on 24-h urine collections for the last 30-40 years to help direct medical therapy in hopes of reducing stone recurrence; yet little progress has been made in preventing stone disease. As such, there is an urgent need to develop reliable a...
