PURPOSE Urinary pH is an important factor linked to renal stone disease and a useful marker in the treatment of urolithiasis. Although the gold standard for measuring urinary pH utilizes a glass electrode and a pH meter, at present dipstick testing is largely used to estimate urinary pH. However, the accuracy and precision of this method may be insufficient for making clinical decisions in pati...

Incidence of urinary calculi and its composition have been showing a remarkable global variation with profound changes in living standards and dietary habits. Indian urinary stone composition is usually different from that of the western countries. Urinary calculi in northern India were composed of pure calcium oxalate monohydrate (COM) and pure calcium oxalate dihydrate (COD) and in Bihar were...

BACKGROUND This study compared the clinical outcomes of extracorporeal shock wave lithotripsy between elderly (aged $65 years) and non-elderly (aged <65 years) patients. METHODS A retrospective review of medical records was performed on 483 (non-elderly: 245, elderly: 238) patients with upper urinary tract stones who underwent shock wave lithotripsy between 2007 and 2015. The demographic data...

Renal stone disease remains a significant health problem in the adult population, with the incidence of urolithiasis estimated to be as high as 12%. The true incidence in childhood is not known, but a frequency of two children per million UK population per annum has been suggested. Understanding the factors involved in urinary stone formation and the appropriate investigations for a child prese...

Combination of 1 alpha(OH) D3(vit D) and ethylene glycol induced renal or ureteral stones or both consisting of calcium oxalate in male Wistar rats. This study investigates the effect of EHDP on calcium oxalate stone using the rat model. EHDP reduced the frequency of renal stone and calcium content in the kidney, and reduced the size of the stones in the renal pelvis and ureter. EHDP biochemica...

We investigated the activity of curcumin against Proteus mirabilis and the struvite crystallization in relation to urinary stones formation. In order to evaluate an activity of curcumin we performed an in vitro experiment of struvite growth from artificial urine. The crystallization process was induced by Proteus mirabilis to mimic the real urinary tract infection, which usually leads to urinar...

OBJECTIVE Due to rapid economic development over the past four decades, urinary stone components may have changed in Taiwan. We studied the changes in urinary stone components over time and the possible association with dietary changes during the same period. MATERIALS AND METHODS From 1956 to 1999, 9,715 urinary calculi were collected at a single institution and analyzed using polarizing mic...

PURPOSE The purpose of this clinical study is to assess the safety and efficiency of a novel lithotripsy method for endoscopic treatment of urinary stones throughout the urinary tract via semi-rigid and flexible endoscopes. This new method is based on the transfer of nanosecond high voltage electric pulses to the stones through flexible probes of various sizes. METHODS The study involved 879 ...

OBJECTIVES To prospectively evaluate the role of double J (DJ) stent in enhancing the passage of fragments in patients undergoing extracorporeal shockwave lithotripsy (SWL) for renal stones with diameters less than 2.5 cm. METHODS Between November 2005 and January 2007, 38 patients with an average age of 47.05 years (range 16-73) were included and underwent SWL for renal stones. The inclusion...

BACKGROUND Kidney stone disease is common in industrialized countries. Recently, it has attracted growing attention, because of its significant association with adverse renal outcomes, including end stage renal disease. Calcium-containing kidney stones are frequent with high recurrence rates. While hypercalciuria is a well-known risk factor, restricted intake of animal protein and sodium, combi...
