Endoscopic papillary balloon dilation (EBD) for choledocholithiasis is known to be comparable to endoscopic sphincterotomy (EST) especially in cases of small stones. With larger stones, EBD with conventional balloon, which have a diameter of 6-8 mm, was reported as less effective for extraction of stones. We evaluated the efficacy and complications of EBD with large balloons (10-15 mm) after li...

OBJECTIVE To present the results of upper calyceal access during percutaneous nephrolithotripsy (PCNL) for stones in the lower calyx, as PCNL is considered the most effective minimally invasive surgery for managing lower calyceal stones, with percutaneous access either directly to the lower calyx or through an upper or middle calyx. PATIENTS AND METHODS The study included 76 patients with sin...

OBJECTIVES AND METHODS Large intracranial calcifications are occasionally encountered in routine computed tomography (CT) scans of the brain. These calcifications, also known as "brain stones", can be classified according to location and aetiology. Combining imaging findings with relevant clinical history and physical examination can help narrow down the differential diagnosis and may allow con...

A single-board certified urologist with training and experience in anesthesiology was assigned to treat 502 patients (185 with renal stones, 317 with ureteral stones) using the Dornier Compact Delta lithotripter under general or epidural anesthesia. Data were obtained regarding stone location, stone size, shockwave use, stone-free rate, and complications. In all, 502 stones were treated with th...

Background: Urinary stones are now a worldwide problem due to rise in occurrence over the past few decades. All racial and cultural groups have experienced this. Complex metabolic environmental risk factors both involved pathogenetic pathways of stone production. This disease affects roughly 12% world's population. Its recurrence rate is about 70% men 47% women. significantly increased prevalen...

Multiple faceted radio-opaque stones within the abdomen are usually situated in the gall bladder, and the incidence of gall stones is increased in patients with Crohn's disease.' Enteroliths may rarely be found in a Meckel's diverticulum,2 and there is an increased-incidence of Meckel's diverticulum in Crohn's disease.3 Stones in a Meckel's diverticulum associated with Crohn's disease have not ...

BACKGROUND The last nationally representative assessment of kidney stone prevalence in the United States occurred in 1994. After a 13-yr hiatus, the National Health and Nutrition Examination Survey (NHANES) reinitiated data collection regarding kidney stone history. OBJECTIVE Describe the current prevalence of stone disease in the United States, and identify factors associated with a history ...

Background: Despite modern antibiotic therapy and technological advances in lithotripsy, the presence of infection in patients with urinary stones, as well as with infectious stones is still a significant cause of morbidity and mortality. Recent findings lend more theories as to how infection leads to stone formation. Aim: The bacteriological study of urine and stone samples from patients with ...

Objective: The purpose of this study was to asses the accuracy of criteria in distinguishing distal urinary stones from phleboliths defined in the literature with thin-slice unenhanced helical computed tomography (CT). Materials and Methods: Between October 2004 and April 2005, we performed 3 cm length thin-slice (2 mm section thickness, pitch:1) helical CT on 31 patients with urinary stones an...
