Background: Calcium tartrate tetrahydrate has been reported as the main mineral in urinary stones in rats that have significant tartrate in their diet, but in humans, there has been only one mention of calcium tartrate stones in the form of bladder stone, and that case was in Africa. Case Presentation: Patient is a 34-year-old Caucasian male who presented with typical symptoms of nephrolithiasi...
OBJECTIVE To assess the efficacy and safety of a "mini-perc" technique of percutaneous nephrolithotomy using a 14-Fr peel-away sheath for the removal of pyelocaliceal stones, and to determine appropriate inclusion criteria. MATERIALS AND METHODS From July 1999 to June 2002, the medical records and radiographic images of 72 patients who underwent the "mini-perc" technique of percutaneous nephr...
OBJECTIVE The prototype artificial neural network (ANN) model was developed using data from patients with renal stone, in order to predict stone-free status and to help in planning treatment with Extracorporeal Shock Wave Lithotripsy (ESWL) for kidney stones. MATERIALS AND METHODS Data were collected from the 203 patients including gender, single or multiple nature of the stone, location of t...
PURPOSE To compare and evaluate the mostly used methods of urinary stone analysis. MATERIALS AND METHODS We searched PubMed and Google Scholar for "urolithiasis, nephrolithiasis, renal stone, and kidney stone" combined with "stone analysis, spectroscopy, X-ray diffraction, chemical analysis, mass spectrometry, and laser-induced breakdown spectroscopy, review article, and quality control asses...
It has been proposed that epithelial dysfunction and inflammation may predispose patients to kidney stone formation. Asthma is another chronic condition related to epithelial dysfunction and inflammation. We hypothesized that pediatric patients with asthma would have an increased prevalence of nephrolithiasis. Furthermore, we investigated if asthma patients with nephrolithiasis have clinical ch...
We present a two-phase model for planning and scheduling of order picking processes. In many warehousing environments order picking processes are organized according to the pick&pack principle. Pickers must build stabile loads during the picking process under strict time constrains. A genetic algorithm with Pareto elitist-based selection has been developed for this multi-criteria optimization p...
Urolithiasis is the third most common urological disease affecting the urinary tract. However, the risk factors that may influnce the calculous kidney damage is still unclear and needs further evaluation. We retrospectively reviewed the records of 661 patients who presented to our hospital and underwent surgery for urolithiasis. All laboratory test results were obtained operatively, within a we...
Traditional Chinese herbal medicine (CHM), which is widely used to treat pain and urolithiasis, is a promising therapy for urinary stone prevention. This study investigated the clinical efficacy of a popular CHM, Wu-Ling-San (WLS), in Taiwan for the prophylaxis of recurrent nephrolithiasis as assessed by surgical stone treatment via a nationwide population-based cohort study. The National Healt...
background nephrolithiasis in children is an important cause of morbidity worldwide. the current retrospective study aims at identifying epidemiological characteristics and risk factors of nephrolithiasis among children under 18 years old attending at nephrology clinic of amir kabir hospital of arak, iran, in 2014. methods the current case-control study was conducted among 166 children in 2 equ...
introduction: to assessment of the efficacy and safety of transurethral cystolithotripsy of large bladder stones by holmium laser in the outpatient setting. methods: in a prospective study, 48 consecutive adult patients with large bladder stones, were enrolled for transurethral cystolithotripsy. patients older than 18 years, with bladder stones larger than 2 cm were enrolled. urethral stricture...
