CONTEXT The role of protein components of pancreatic secretions has been controversial in pancreatic stone formation. OBJECTIVE To study the lithogenic role of pancreatic stone protein and lactoferrin in stone formation in chronic pancreatitis. PATIENTS Pancreatic stones were collected from 13 patients with alcoholic (n=6) and nonalcoholic (n=7) chronic calcified pancreatitis. MAIN OUTCOM...

BACKGROUND It remains controversial as to whether active stone removal should be performed in patients with poor performance status because of their short life expectancy and perioperative risks. Our objectives were to evaluate treatment outcomes of active stone removal in patients with poor performance status and to compare life prognosis with those managed conservatively. METHODS We retrosp...

PURPOSE Several factors determine the success of extracorporeal shockwave lithotripsy (SWL) for kidney stones: stone size, stone location within the collecting system, stone type, and the SWL machine used. It has been suggested that stone radiodensity, as determined either by plain radiography or computed tomography attenuation values, may be an independent predictor of SWL success. We examined...

Purpose To evaluate the impact of various computed tomography scan-based parameters of renal stones on the outcome of extracorporeal shock wave lithotripsy (ESWL). Materials and Methods We conducted a retrospective study of patients who underwent ESWL for renal stones (sized 5-20 mm) from January 2013 to December 2016. We evaluated body mass index, location of the stone, skin-to-stone distanc...

There is a significant lack of unified approaches to building generally intelligent machines. The majority of current artificial intelligence research operates within a very narrow field of focus, frequently without considering the importance of the 'big picture'. In this document, we seek to describe and unify principles that guide the basis of our development of general artificial intelligenc...

Objectives: Percutaneous nephrolithotomy on staghorn calculi is challenging for urologists because it is difficult to remove all of the stones. The purpose of this study was to evaluate the associated factors of stone-free rate after primary percutaneous nephrolithotomy on staghorn calculi in a large series of patients at a single, tertiary referral, endourologic stone center. Methods: We colle...

OBJECTIVE To evaluate the efficacy of extracorporeal shock wave lithotripsy (ESWL) for distal ureteric calculi (DUC) and to determine variables that could affect the outcome results. PATIENTS AND METHODS Between April 2004 and February 2008, 100 patients with a solitary DUC were treated with in situ ESWL using a lithotripter (Lithostar Plus, Siemens, Erlangen, Germany). The outcome of treatme...

Abstract Background: Stphylococcus cohnii is an organism of coagulase negative species which is considered as normal flora. However, it has been isolated from urinary tract infections and surgical prostheses but its relation with staghorn stones has not been reported, yet. Case Presentation: A 50-years-old woman presented with left renal staghorn stone in June 2014. She had bilateral staghorn...

Abstract Artificial Intelligence has left no stone unturned, and mechanical engineering is one of its biggest consumers. Such technological advancements in metal melting can help process simplification, hazard reduction, human involvement reduction & lesser time. Implementing the AI models technology will ultimately various industries, i.e., Foundry, Architecture, Jewelry Industry, etc. Thi...

CONTEXT An optimum metabolic evaluation strategy for urinary stone patients has not been clearly defined. OBJECTIVE To evaluate the optimum strategy for metabolic stone evaluation and management to prevent recurrent urinary stones. EVIDENCE ACQUISITION Several databases were searched to identify studies on the metabolic evaluation and prevention of stone recurrence in urolithiasis patients....
