Patients with multiple cholesterol gallbladder stones have been found to be at a higher risk for the recurrence of gallstones after successful nonsurgical treatment than those with a solitary stone. Cholesterol gallstone recurrence, like primary gallstone formation, probably involves a triple defect with supersaturation, abnormally rapid nucleation of cholesterol in bile and altered gallbladder...

Calcium oxalate kidney stones contain low amounts of proteins, some of which have been implicated in progression or prevention of kidney stone formation. To gain insights into the pathophysiology of urolithiasis, we have characterized protein components of calcium oxalate kidney stones by proteomic approaches. Proteins extracted from kidney stones showed highly heterogeneous migration patterns ...

This study reports biochemical composition and morphological aspect of gallstones as investigated by spectroscopy IR method. Participants were 24 patients composed of 12 males and 12 females who underwent cholecystectomy with age mean of 44.8 years. The gallstones were classified either as pigments stones (n = 12), cholesterol stones (n = 8) or as mixed stones (n = 4) according to analysis by F...

BACKGROUND Some patients with common bile duct (CBD) stones develop cholangitis requiring drainage, while others do not. The aims of this study were to elucidate the clinical differences among patients with CBD stones who required and did not require emergent drainage, and to identify risk factors for the development of cholangitis requiring emergent drainage in patients with silent CBD stones....

Objective: To determine the chemical composition of spontaneously passed urinary stones. Study design: Descriptive. Place and duration: The study was conducted at public and private Pathology laboratories of Larkana from Jan: 2009 to Dec: 2010. Patients and methods: Stones of 278 patients were analyzed chemically, using titrimetric method for estimation of calcium and colorimetric method for ur...

Kidney stones are one of the most common chronic disorders in industrialized countries. In patients with kidney stones, the goal of medical therapy is to prevent the formation of new kidney stones and to reduce growth of existing stones. The evaluation of the patient with kidney stones should identify dietary, environmental, and genetic factors that contribute to stone risk. Radiologic studies ...
