The high success rates of extracorporeal shockwave lithotripsy and endourological techniques, together with their ease of use, in the treatment of urinary stones often overshadow the importance of the metabolic component of stone disease. It is my opinion that the prevention of further stones complements management of the acute episode. This review summarizes a variety of approaches to the meas...

PURPOSE To assess the potential of dual-energy computed tomography (DECT) to identify urinary stone components, particularly uric acid and calcium oxalate monohydrate, which are unsuitable for extracorporeal shock wave lithotripsy (ESWL). MATERIALS AND METHODS This clinical study included 246 patients who underwent removal of urinary stones and an analysis of stone components between November...

Patients 120 men (mean age 45 y) who had idiopathic hypercalciuria (urinary calcium excretion > 300 mg/d) on an unrestricted diet, recurrent formation of calcium oxalate stones ( ≥ 2 colic episodes with expulsion of stones or radiographic evidence of retained stones), no known condition commonly associated with calcium nephrolithiasis, no previous visit to a stone disease centre, and no current...

OBJECTIVE The objective was to determine the incidence of bladder stones in patients with spinal cord injury (SCI) and to assess if catheter encrustation or positive urinary culture of Proteus mirabilis is predictive of bladder stones. BACKGROUND Bladder stones are common urological complication in those with SCI managed with indwelling urinary catheter. Detection and removal of bladder stone...

Dietary approaches and medical treatment can prevent recurrence of urinary stones. Some interventions are appropriate for all types of stones, but there are particular risk factors that may need directed therapy.

INTRODUCTION Here we report an unusual case of massive stone formation in augmented urinary bladder. CASE PRESENTATION A 25-year-old man presented with recurrent urinary tract infection ten years after augmentation cystoplasty after a complex pelvic fracture urethral distraction defect. On evaluation by ultrasonography, X-ray, and computed tomography of abdomen showed large burden of stones i...

A retrospective survey was made of 305 patients with proved urinary calculi. When those patients with a solitary stone were compared with those with multiple stones no diagnostically helpful difference was noted in the prevalence of abnormal serum or urine biochemistry, urinary infection, or anatomical abnormality of the urinary tract. The same was true of the stone composition and the need for...
