Previous studies have suggested a relationship between bile duct stones and periampullary duodenal diverticula. The aim of the present study was to examine this association in more detail, including step-wise logistic regression to identify independent predictors for the presence of diverticula. Clinical, endoscopic and radiological data were analysed from 794 consecutive subjects with bile duc...

BACKGROUND Patients with symptomatic kidney stones are characterized by older age, male gender, white race, hypertension, obesity, metabolic syndrome and chronic kidney disease. Whether these characteristics differ in patients with asymptomatic kidney stones is unknown. METHODS All potential kidney donors who underwent protocol computed tomography angiograms/urograms (2000-08) at the Mayo Cli...

A 52-year-old man was referred for the evaluation of mild renal failure with severe hypertension (220/130mmHg), which was resistant to combination therapy of a calcium channel blocker and an angiotensin II receptor blocker. Although he reported no past history indicating urolithiasis, urinalysis revealed plenty of round brownish stones (Figure 1A). The stones resembled uric acid (UA) stones (Fi...

A total of 133 stones in renoureteral and bladder units from 122 patients, 8 to 80 years old, were treated by extracorporeal shock wave lithotripsy (ESWL) with the Wolf Piezolith device from November 1989 through December 1990. The 133 stones involved renal stones (91), ureter stones (34) and bladder stones (9). The number of shock waves per session was up to 4,000 shots, the mean number of sho...

INTRODUCTION Gall bladder is a pear shaped secular Organ which stores bile, is also place for formation and growth of gall stones. Today the incidence of Cholelithiasis is increasing considerably in India. The aim of our study are to know the incidence of gall stones in relation to age and sex, the relation of diet in gall stones, the clinical presentation of gall stones, the best mode of inves...

introduction: few researches have been conducted researches on the influence of the type of dental stone used for fabrication of casts on the adaptation of denture bases. the purpose of this study was to compare the effect of two types of stone casts on the accuracy of fit in complete denture bases. methods: using sixty fully replicated master casts obtained by duplicating a metal die represent...

30 cases of obstructing proximal ureteral stones at the level of l3-l5 which could not be pushed back into the pelvis and passed by a guide wire under epidural anesthesia, were removed percutaneously with the rigid ureteroscope. multiple stones in one ureter, bilateral ureteral stones and a ureteral stone of a solitary kidney were removed successfully in one session showing the reliability and ...

BACKGROUND The objective of this study was to analyze gallbladder stones for direct evidence of a relationship between Clonorchis sinensis infection and gallbladder stones formation. METHODOLOGY We investigated one hundred eighty-three gallbladder stones for the presence of Clonorchis sinensis eggs using microscopy, and analyzed their composition using Fourier transform infrared spectroscopy....

background retrograde intra-renal surgery (rirs) has been used to remove stones of less than 2 cm in the kidney. however, its role is not well defined. objectives the objective of this study was to evaluate the outcomes and safety of rirs, used either as a primary or secondary procedure, and to analyze factors predicting the stonefree rate (sfr). patients and methods a retrospective analysis wa...

     Salt crystallization is one of the most powerful weathering agents that may cause a rapid change in the mechanical properties of stones, and thus limit their durability. Consequently, determining the mechanical properties of stones due to salt crystallization is important for natural building stones used in marine environmental and mild climatic conditions, which expose excessive salt crys...
