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...

OBJECTIVE To study the effect of ascorbic acid (AA) supplementation on urinary pH, metabolic stone workup parameters, and development of de novo urolithiasis in stone-forming patients. MATERIAL AND METHODS A retrospective review of the patients followed-up at a tertiary stone centre between September 2009 and October 2015 was performed. Patients with recurrent urolithiasis who received AA sup...

Transl Androl Urol 2014;3(3):241 www.amepc.org/tau The regulation of dietary and supplemental calcium intake in relation to urinary stone disease is not well understood (1). For instance, why do most patients with primary hyperparathyroidism with markedly increased serum and urinary calcium not have a history of urinary stone disease? There must be other factors involved in stone formation. Cal...

Urinary stone disease is global problem and is due to alteration in the normal crystallization environment of urine in the urinary tract systems. Major factors responsible for crystal formation are super-saturation of Ca salts and level of crystallization inhibitors (Citrate & Phytate). Excessive citrate intake makes the urine more alkaline (pH between 6 and 7). This can be achieved by oral adm...

After stone removal, accurate analysis of urinary stone composition is the most crucial laboratory diagnostic procedure for the treatment and recurrence prevention in the stone-forming patient. The most common techniques for routine analysis of stones are infrared spectroscopy, X-ray diffraction and chemical analysis. The aim of the present study was to assess the quality of urinary stone analy...

A 3-year retrospective study (January 1995 to December 1997) of all treatment modalities for urinary stone disease done in the Department of Urology, Singapore General Hospital was documented, and open stone surgery identified. Patient's characteristics, stone burden, surgical factors, indications and outcome were reviewed for each patient. Of the 2651 procedures performed for urinary stone dis...

OBJECTIVE Diet interventions may reduce the risk of urinary stone formation and its recurrence, but there is no conclusive consensus in the literature regarding the effectiveness of dietary interventions and recommendations about specific diets for patients with urinary calculi. The aim of this study was to review the studies reporting the effects of different dietary interventions for the modi...

Urinary stone disease affects up to 15% of people globally. The etiology of stones may range from nutrition to behavior to genetics. After a first time occurence of a sympomatic stone, up to 50% of patients may experience another stone within 5 years. Thus, metabolic evaluation for the prevention of stone recurrence can play a major role in reducing the morbidity associated with urinary stones....
