Background. Most common bile duct (CBD) stones can be removed with standard techniques using endoscopic retrograde cholangiopancreatography (ERCP), but in some cases additional methods are needed. In this study we aimed to investigate the management of patients with difficult stones and the factors that affect the outcome of patients that have undergone periodic endobiliary stenting. Materials ...

Introduction Mineralization inhibitors are required to prevent the precipitation of minerals and inhibit the formation of kidney stones and other ectopic calcifications. In laboratory studies, Fetuin-A as a glycoprotein has inhibited hydroxyapatite precipitation in calcium and phosphate supersaturated solutions; however, information about patients with kidney stones is limited. The aim of this ...

Purpose: To evaluate the ultrastructural features of the urinary stones removed with endoscopic stone surgery, using micro computed tomography (micro-CT). Materials and Methods: Patients who had endoscopic surgery for renal or ureteral stones removal were included in this study. After surgery, the stones were classified into three groups and investigated with Skyscan 1174 micro-CT. Group I unde...

OBJECTIVES/HYPOTHESIS To examine how preoperative imaging characteristics correlate with sialendoscopic findings and operative outcomes in patients with obstructive parotid symptoms. STUDY DESIGN Retrospective review. METHODS We identified 112 consecutive patients who underwent 134 unilateral or bilateral parotid gland sialendoscopies between December 2005 and August 2013. We reviewed clini...

Stones in the biliary tree may coexist with gall-bladder stones, may be found only in the common duct (in the absence of gall-bladder stones) or, more rarely, may be present in the intrahepatic biliary tree-as in the Caroli syndrome.1 One of the most frequent causes of choledocholithiasis, however, is the retained common duct stone which has been left behind inadvertently after elective or emer...

Serum concentrations of symmetric dimethylarginine (SDMA) correlate with renal function in cats and SDMA has been shown to be a more reliable and earlier marker for chronic kidney disease (CKD) compared with serum creatinine (Cr). Calcium oxalate uroliths tend to develop in mid-to-older aged cats and kidney stones may cause a reduction in renal function with increased SDMA, but normal serum Cr....

OBJECTIVE Epidemiological data reveal that the overall risk for kidney stones disease is lower for women compared to age-matched men. However, the beneficial effect for the female sex is lost upon menopause, a time corresponding to the onset of fall in estrogen levels. The aim of this study was to describe the serum estradiol (E2) and testosterone (T) characteristics of naturally postmenopausal...

results in group 1, the mean largest and cumulative stone diameters, respectively, were 18.7 ± 5.7 mm and 45.0 ± 12.0 mm. in group 2, the mean volume was 6,288.4 ± 2,733.0 mm3. the overall sf was 96.4% (100% for group 1 and 75% for group 2). the mean number of sessions of eswl and urs, respectively, was 1.4 ± 0.7 and 0.8 ± 0.9 in group 1 and 4.0 ± 2.0 and 1.5 ± 1.3 in group 2. the mean times to...

Biliary infections are an important cause of morbidity in the Western world. With regard to epidemiology, etiology, microbiological spectrum, prevalence, location and composition of gallstones, pathogenesis, clinical sign and therapy, there are large differences between the spectrum of biliary infections in the East and in the West (Table 1). In Western countries, gallstones are found in 10 to ...

INTRODUCTION To investigate retrospectively the impact of urinary stone volume on computed tomography stone attenuations measured in Hounsfield units in 253 patients with urolithiasis. MATERIAL AND METHODS CT scans were performed in 253 patients with suspected urinary stone disease from 2008 to 2010 using CT-Scanner Siemens, SOMATOM, Sensation 64. One experienced radiologist (A.L) who was bli...
