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...

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 Ryugu is a second-generation C-type asteroid formed by the reassembly of fragments previous larger body in main belt. While majority samples returned Hayabusa2 are composed lithology dominated aqueously altered minerals, clasts pristine olivine and pyroxene remain least-altered lithologies. These objects great interest for revealing composition dust from which original building blocks ...

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....

BACKGROUND It is unclear whether parenchymal thickness (PT), in combination with stone density measured by Hounsfield Units (HU), affects stone-free rates after PCNL. The aim of the present study was to investigate the relationship between PT in combination with stone density values and the outcomes of PCNL. MATERIAL AND METHODS From 2009 to 2014, data from 216 PCNL patients were prospectively ...

BACKGROUND It is well known that many diseases may be associated with obesity resulting from an energy-rich diet, and that a westernized diet may increase the incidence of urinary stone formation. To evaluate degree of obesity, we investigated body mass index (BMI) in patients with calcium containing upper urinary stones and examined their blood with regard to lipid metabolism. METHODS Betwee...
