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...

introduction: the aim of this study is to compare holmium laser (ll) with pneumatic lithoclast (pl) in patients with upper ureteral stones and their ability to destruct the stones and making the patient stone free. we also compare the duration of these procedures and their complications, such as urosepsis, perforation, and pushing the stone backward. methods: this has been a clinical randomized...

Three patients were reinspected by ureteroscopy after repeat ESWL. Ureteroscopy initially did not disclose an intraluminal stone and only visualized a severe inflammatory reaction of the ureteric wall and a boss of the ureter at the level of the fluoroscopically suspected stone location. An intact stone in all 3 cases was finally exposed by tactile contact at the top of the ureteroscope after p...

BACKGROUND Complete blood count (CBC) parameters may associated with multiple diseases. Urinary stone disease is common public problem. Predictive value of CBC parameters may be associated with urinary stone disease. OBJECTIVES To analyze the association between complete blood count (CBC) parameters and urinary stone disease. PATIENTS AND METHODS This study was a retrospective observational...

A Stone-Weierstraß type theorem for semiuniform convergence spaces is proved. It implies the classical Stone-Weierstraß theorem as well as a Stone-Weierstraß type theorem for filter spaces due to Bentley, Hušek and Lowen-Colebunders [1].

Kidney stone disease has become more common in children, but it remains non diagnosed in a significant proportion of patients, due to a lack of notable signs and symptoms. All children with colicky abdominal pain or microscopic hematuria should be examined thoroughly for urolithiasis. Patients’ histories in terms of family, medical, and drug and a thorough physical examination are require...

Renal stone disease covers kidney and lower urinary tract stones caused by a variety of conditions, including metabolic and inherited disorders, and anatomical defects with or without chronic urinary infection. Most cases are idiopathic, in which there is undoubtedly a genetic predisposition, but where environmental and lifestyle factors play an important role. Indeed, it is becoming apparent t...

Curling is a sport played on ice in which two teams each deliver 8 granite stones towards a target, or 'house'. It is the only sport in which the trajectory of the projectile can be influenced after it has been released by the athlete. This is achieved by sweeping the ice in front of the stone to change the stone-ice friction and thereby enable to stone to travel further, curl more or stay stra...

The purpose of this study was to define factors that have a significant impact on the stone-free rate after ESWL. Methods: A total of 417 patients harboring renal or ureteral stones underwent extracorporeal shock wave lithotripsy (ESWL) between October 2008 and July 2012. Eighty five patients were lost on follow up. The remaining (n = 332). All patients were >18 yr of age. Siemens and SLX-F2 el...
