Oral cholecystography repeated at six-months intervals is the standard method for determining reduction in size of gall stones (partial success) and complete dissolution of stones (complete success). In a comparative study of oral cholecystography and cholecystosonography six out of 14 patients with gall stones achieving complete success by oral cholecystographic criteria had stones still detec...

The aim of this study was to perform phenotype analysis and dentin sialophosphoprotein (DSPP) mutational analysis on 3 Brazilian families diagnosed with dentinogenesis imperfecta type II (DGI-II) attending the Dental Anomalies Clinic in Brasilia, Brazil. Physical and oral examinations, as well as radiographic and histopathological analyses, were performed on 28 affected and unaffected individua...

Current projected missions to Mars will require 18 to 24 months of exposure to microgravity conditions, which might have serious effects on human physiology, including that of the oral cavity. Very few studies have been published on the effect of microgravity on the oral cavity, although it has been reported that microgravity increases the prevalence of periodontitis, dental caries, bone loss a...

PURPOSE The objective of this study were to evaluate the location of ureteral stones and the diameter of the ureter in patients with renal colic. MATERIALS AND METHODS We retrospectively reviewed the records of 95 consecutive patients who presented to the emergency department with renal colic in whom urinary stones were diagnosed by computed tomography between January 2009 and August 2009. Th...

Isolation of Nanobacteria from different types of urinary tract stones from different populations all over the world raises the possibility that these microorganisms are etiological agents of these stones. The aim of this study was to isolate and identify the nanobacteria from different types of human urinary tract stones and serum from Egyptian population. We searched for nanobacteria from ten...

Recent population studies have found symptomatic kidney stone formers to be at increased risk for chronic kidney disease (CKD). Although kidney stones are not commonly identified as the primary cause of ESRD, they still may be important contributing factors. Paradoxically, CKD can be protective against forming kidney stones because of the substantial reduction in urine calcium excretion. Among ...

Since medical treatment of gallstones is confined to cholesterol-rich stones, the ability of clinical radiographs to predict gallstone type was tested prospectively by comparing the preoperative radiological appearance of gallstones from 57 unselected patients with cholelithiasis coming to cholecystectomy with the subsequent analysis of the stones both by X-ray diffraction and by chemical techn...

PURPOSE To evaluate the treatment success rate of flexible ureterorenoscopy (URS) for opaque and non-opaque renal stones. MATERIALS AND METHODS Ninety-four patients, who underwent flexible URS for renal stones between October 2012 and January 2014, were included. The patients were divided into two groups according to stone radiolucency. The patients were evaluated with preoperative and postop...
