Abstract Objective To compare the clinical characteristics of infectious and non-infectious stones in patients with urinary tract infections caused by Proteus mirabilis and to explore associated influencing factors. Meth...

Introduction: Gallstone disease is a prevalent gastrointestinal disorder, often managed surgically via Laparoscopic Cholecystectomy (LC), which is considered the current gold standard. However, Gallbladder Wall Thickness...

Abstract Objective Accurate preoperative stone size assessment is crucial for predicting outcomes after percutaneous nephrolithotomy (PCNL), yet a gap persists between the accurate but impractical gold standard (3D softw...

Introduction and importanceBouveret syndrome is a rare form of gallstone ileus characterized by gastric outlet obstruction secondary to impaction of a gallstone that has migrated into the gastrointestinal tract through a...

BackgroundEndoscopic retrograde cholangiopancreatography (ERCP) is a critical therapeutic modality for bile duct stones; however, cases of cystic duct stones (CDS) managed by ERCP alone are rarely reported. Herein, we pr...

Abstract Background Impacted upper ureteral stones pose a significant risk of ureteral injury and stricture formation during ureteroscopic procedures. The Flexible and Navigable Suction Ureteral Access Sheath (FANS) inte...

Abstract Background Management of upper urinary tract stones with moderate-to-severe hydronephrosis remains challenging due to altered renal anatomy and higher complication risks. Flexible negative-pressure ureteral shea...

In this paper, the assessment of the radon exhalation rate of the Modica stone building material, untreated and accelerated aged through salt crystallization test, is reported as a case study. Noteworthy, this constructi...

In this paper we give a constructive proof that the variety of Boolean algebras has the strong amalgamation property by describing constructively the strong amalgams in the variety. Then, capitalizing on this constructio...

Ureteral calculi are common in urological practice, and ureteroscopic holmium laser lithotripsy (HLUL) is the preferred minimally invasive treatment. However, postoperative residual fragments and inflammatory responses r...

Abstract Background This study compared the clinical performance of 7.5 F and 9 F digital flexible ureteroscopes in sheathless retrograde intrarenal surgery (RIRS), with a particular focus on how ureteroscope caliber i...

This study was conducted to determine the frequency of renal stones in patients diagnosed with chronic kidney disease. A total of 226 participants aged 18–60 years of both genders with CKD were enrolled using consecuti...

This research designs a sustainable composite material using PLA, palm biomass, and ground volcanic stone (VSMGP) to improve mechanical and insulation efficiency for green construction. The raw materials were dried , sie...

Key Points. Physiological normothermic machine perfusion kept kidneys viable for 12 hours with better hemodynamics, urine output, and metabolic stability than clinical normothermic machine perfusion. Physiological normot...

Selective electrochemical CO₂ reduction to multi-carbon products remains a central bottleneck for carbon-neutral chemical manufacturing, with most catalysts achieving C₂⁺ Faradaic efficiencies below 75%. This inves...

Abstract Bryophytes disperse efficiently via wind-borne spores, yet long-distance transport alone does not guarantee successful establishment at the deposition site. Species-rich hotspots are expected to arise where a su...

To make a decision or determine the order of things, people commonly use binary choices such as tossing a coin, with an assumption that the empirical probability equals to the theoretical probability. However, recent und...

Abstract Background Dental plaster, dental stone, and improved stone are commonly used gypsum products for dental molds. While improved stone is preferred for final molds due to its strength, dental plaster is cheaper bu...

ABSTRACT Background and Aims T‐tube drainage has traditionally been used after laparoscopic common bile duct exploration (LCBDE) to reduce the risk of bile leakage; however, it is associated with prolonged hospital sta...

Abstract Background Silicosis is an irreversible scarring lung disease caused by occupational respirable crystalline silica (RCS) dust exposure. Mineral (noncoal) miners who extract metal, nonmetal, stone, and sand/grave...

Abstract We employ density functional theory (DFT) to investigate how Stone–Wales (SW) defects modulate the electronic and electrochemical properties of two-dimensional silicon carbide (SiC) monolayer for sodium (Na)-,...
