One of the most common types of urinary stones formed in humans and some other mammals is composed of calcium oxalate in ordered hydrated crystals. Many studies have reported a range of metals other than calcium in human stones, but few have looked at stones from animal models such as the dog. Therefore, we determined the elemental profile of canine calcium oxalate urinary stones and compared i...

OBJECTIVE In this study we planned to investigate the relationship between presence of kidney stones and stone burden with hypertension (HT), diabetes mellitus (DM) and body mass index (BMI). METHODS A total of 574 patients were included in the study. None of the patients had a history of stones. The 121 patients with kidney stone identified on ultrasound evaluation and the 453 patients with ...

PURPOSE To determine the efficiency of slow delivery rate of shockwaves (SW) on stone fragmentation and treatment outcomes in patients with renal and ureteral calculi. PATIENTS AND METHOD Using the Siemens Lithostar Multiline, we treated 843 patients (229 renal and 614 ureteral stones) at a fast delivery rate (120 SW/min, between October 2003 and August 2006), 448 patients (139 renal and 309 ...

PURPOSE To report the outcome of laparoscopic pyelo- and ureterolithotomies with the aid of flexible nephroscopy. MATERIALS AND METHODS A retrospective analysis was performed in 71 patients with complex renal stones or large and impacted proximal ureteral stones. Patients underwent laparoscopic pyelo- or ureterolithotomies with or without the removal of small residual stones by use of flexibl...

INTRODUCTION We analyze our recent results and discuss the advantages and disadvantages of bilateral single-session ureterorenoscopy (URS) for bilateral ureteral stones. PATIENTS AND METHODS 55 patients underwent URS with pneumatic lithotripsy (PL) for bilateral stones. 61 (55.5%), 28 (25.4%) and 21 (19.1%) stones were located in the lower, middle and upper ureter, respectively. RESULTS Of ...

melamine is a new risk of urinary stones. gansu province is a heavily affected area and has large population and underdeveloped economy. we hypothesized that number of family members and family income may play significant roles in the formation of urinary stones. a case-control study was performed among 190 infants. results showed that the case group had less numbers of family members than the ...

Background: Pulp stones are calcification in the dental pulp which can be present either in deciduous or permanent teeth. Exact causes of pulp stones are not known and several elements have been associated. It can be seen in healthy, diseased or as a part of various syndromes. Frequency of pulp stones fluctuated from 8 to 95% depending on the population studied. Our study is an attempt to know ...

Patients with multiple cholesterol gallbladder stones have been found to be at a higher risk for the recurrence of gallstones after successful nonsurgical treatment than those with a solitary stone. Cholesterol gallstone recurrence, like primary gallstone formation, probably involves a triple defect with supersaturation, abnormally rapid nucleation of cholesterol in bile and altered gallbladder...

Calcium oxalate kidney stones contain low amounts of proteins, some of which have been implicated in progression or prevention of kidney stone formation. To gain insights into the pathophysiology of urolithiasis, we have characterized protein components of calcium oxalate kidney stones by proteomic approaches. Proteins extracted from kidney stones showed highly heterogeneous migration patterns ...
