Pediatric urolithiasis is an important medical problem, which has seen an increasing incidence in developing countries. A wide geographic variation in urolithiasis prevalence has been documented, which might be due to differences in diet, fluid intake, ethnicity and climate. The aim is to assess the biochemical and metabolic characteristics of the patients. The current study was conducted by th...

Prevalence of urolithiasis in childhood is increasing. The wide geographic variation in the incidence of lithiasis in childhood is related to climatic, dietary, and socioeconomic factors. Many children with stone disease have a metabolic abnormality. In Southeast Asia, urinary calculi are endemic and are related to dietary factors. The main aim of this study was to determine the prevalence of r...

The delineation of cystinuria into two types, 'recessive' and 'incompletely recessive', according to a differential expression of the gene defect in carriers by urinary parameters (Harris et al., 1955a, b), has been further refined into three forms by including in phenotype analysis evidence for heterogeneity (Rosenberg, 1966; Rosenberg et al., 1966) of the accompanying intestinal transport def...

The objective of this study was to evaluate the levels sulfur amino acids in diets laying hens 34-50 weeks age. 336 Dekalb White birds were distributed a completely randomized design with six treatments, 14 replicates four each. consisted control treatment, formulated meet nutritional requirements according NRC (1994) and five varying methionine plus cystine level (0.536, 0.603, 0.670, 0.737, 0...

Medical literature indicates clearly that cystinuria and cystinosis, two severe genetic pathologies, are related to the presence of abnormal L-cystine deposits. While adopts a hexagonal crystal morphology consistent with its crystallographic structure (hexagonal, P6 1 22 space group), deposits cystinosis display rectangular shape. Because this is unexpected from L-cystine, we have investigated ...

PURPOSE To compare the efficiency and cost effectiveness of a combined pneumatic and ultrasonic lithotrite (Lithoclast Ultra) and a standard ultrasonic lithotrite, (LUS-1) during percutaneous nephrolithotomy. MATERIALS AND METHODS In a prospective randomized trial, 30 patients undergoing percutaneous nephrolithotomy (PCNL) were randomized to PCNL with either the combined pneumatic and ultraso...

ABSTRACT: 
 Aim:
 To determine the density and chemical structure of renal stones by using in vivo low dose helical computerized tomography.
 Methods:
 79 patients with or uretheral were included our study who going to have extracorporeal shock wave lithotripsy (ESWL) planned go through urinary stone surgery due stones. All densities measured Hounsfield Unit abdominal non-co...

OBJECTIVE To evaluate trends in urolith composition and urolithiasis in dogs during the past 21 years. DESIGN Retrospective case series. SAMPLE POPULATION 25,499 uroliths and the dogs from which they were obtained. PROCEDURES Database of the Gerald V. Ling Urinary Stone Analysis Laboratory was searched from January 1985 through December 2006. All uroliths from dogs and the accompanying su...

A retrospective review was performed of the records of 148 Croatian children with urolithiasis treated between 1989 and 2003. The study evaluated age, gender, family history, clinical symptoms, location of stone, laboratory findings, stone composition, mode of treatment and compared our results with data from higher and lower socio-economic countries. The mean age of our patients was 9.38 years...
