Objective: Silent and not yet discovered stones of the upper urinary tract are potentially dangerous since in due course they may cause infection, obstruction and renal damage. The aim of this study was to determine the incidence of such silent kidney stones in a representative Pakistani population of the Karachi area. Subjects and Methods: We studied 201 consecutive subjects at our hospital wh...

Purpose To compare the results of a chemical method of kidney stone analysis with the results of Fourier transform infrared (FT-IR) spectroscopy. Materials and Methods Kidney stones collected between June and October 2015 were simultaneously analyzed by chemical and FT-IR methods. Results Kidney stones (n=449) were collected from patients from 1 to 81 years old. Most stones were from adults...

Kidney stones are small, hard deposits of mineral and acid salts that separate out from urine in the urinary tract. They can vary in size and location. While small stones can pass through the urinary system without causing symptoms, larger stones can cause serious morbidity, pain, haematuria, infection, decreased kidney function and kidney failure can cause severe pain.

BACKGROUND AND OBJECTIVES Not all fluids may be equally beneficial for reducing the risk of kidney stones. In particular, it is not clear whether sugar and artificially sweetened soda increase the risk. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We prospectively analyzed the association between intake of several types of beverages and incidence of kidney stones in three large ongoing cohor...

Nephrolithiasis is one of the most frequent urologic diseases. The aim of this paper is to study the composition and frequency of 8854 patient kidney stones and in a subset of them their metabolic risk factors to be related to their type of calculi. Physicochemical and crystallographic methods were used to assess kidney stone composition. In a subset of 715 patients, we performed an ambulatory ...

BACKGROUND Gallstones and kidney stones are known complications of inflammatory bowel diseases (IBD). Risk factors have been insufficiently studied and explanatory studies date back up to 30 years. It remains unclear, whether improved treatment options also influenced risk factors for these complications. OBJECTIVES Identifying risk factors for gallstones and kidney stones in IBD patients. ...

Introduction Urinary stones are of the most tragic causes of visiting hospitals. Although the cause of the infection and the incidence of kidney stones are not well known, while there are factors known involves in its development (1). Sex, water and age and its minerals, diet, climate and genetic are of the affecting factors (2). These patients are susceptible to renal failure, urinary tract in...
