INTRODUCTION The accurate diagnosis of submucosal ureteral stones in order to choose a proper and less complicative method of treatment is of significant importance. The use of KUB to detect submucosal ureteral stones has been studied in this research. MATERIALS AND METHODS This prospective study has been carried out on 33 patients (23 males and 10 females) with lower ureteral stone (17 cases...

PURPOSE To determine whether the distance from skin to stone, as measured by computed tomography (CT) scans, could affect the stone-free rate achieved via extracorporeal shock wave lithotripsy (ESWL) in renal stone patients. MATERIALS AND METHODS We retrospectively reviewed the records 573 patients who had undergone ESWL at our institution between January 2006 and January 2010 for urinary sto...

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...

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...
