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....

Stone formation is a known long-term complications of continent urinary reservoirs. We present a rare case of a large stone in a continent cutaneous reservoir in a 56-year-old male managed with percutaneous cystolithotomy. The patient presented with recurrent urinary tract infections and stomal incontinence. CT revealed an 8-cm stone occupying the entire lumen of his reservoir. Rather than remo...

BACKGROUND A wide variety of complications due to the extrauterine migration of intrauterine contraceptive devices have been reported in the literature. Here we describe the case of a large bladder stone formed around a migrated Copper T380A device that was neglected and detected 15 years after insertion. CASE PRESENTATION A 48-year-old Sri Lankan woman underwent a workup for lower urinary tr...

BACKGROUND To determine incidence of renal stone disease in patients with urinary tract infection, this cross sectional study was conducted at Surgical Unit of District Head Quarters Hospital, Charsadda over a period of one year from January to December 2005. METHODS One hundred consecutive patients were enrolled in this study. All those patients who presented with urinary symptoms were inclu...

CONTEXT An optimum metabolic evaluation strategy for urinary stone patients has not been clearly defined. OBJECTIVE To evaluate the optimum strategy for metabolic stone evaluation and management to prevent recurrent urinary stones. EVIDENCE ACQUISITION Several databases were searched to identify studies on the metabolic evaluation and prevention of stone recurrence in urolithiasis patients....

PURPOSE To report the outcomes of laparoscopic surgery combined with endourological assistance for the treatment of renal stones in patients with associated anomalies of the urinary tract. To discuss the role of laparoscopy in kidney stone disease. MATERIALS AND METHODS Thirteen patients with renal stones and concomitant urinary anomalies underwent laparoscopic stone surgery combined with anc...

Although the prevalence of urolithiasis is nearly 2-3% in childhood, the risk of recurrence may range from 6.5-54%. There has been an increase in urinary stone disease among pediatric age groups, and stone disease has a multifactorial etiology. After the diagnosis, detailed metabolic evaluation is required. High recurrence rates, therapeutic irregularities and deficiency in diagnosis may lead t...

OBJECTIVE To present our experience in surgical management of urolithiasis in patients after urinary diversion. PATIENTS AND METHODS Twenty patients with urolithiasis after urinary diversion received intervention. Percutaneous nephrolithotomy, percutaneous based antegrade ureteroscopy with semi-rigid or flexible ureteroscope, transurethral reservoir lithotripsy, percutaneous pouch lithotripsy...

A high urinary pH is main risk factor for the calcium phosphate stone formation; however, its pathophysiologic mechanism has not been fully understood. The introduction of Topiramate in the treatment of various neurological disorders has been complicated by metabolic acidosis, significant hypocitraturia, elevated urinary pH, and calcium phosphate stone formation. This model provides a probe to ...
