Kidney stones have been rising in prevalence in the United States and worldwide, and represent a significant cost burden. Cost effectiveness research in this area may enable improvements in treatment efficiency that can benefit patients, providers and the healthcare system. There has been limited research in the cost effectiveness of surgical interventions for stone disease, despite the diverse...

PURPOSE To report the outcomes of laparoscopic surgery combined with endourological assistance for the treatment of renal stones in patients with associated anomalies of the urinary tract. To discuss the role of laparoscopy in kidney stone disease. MATERIALS AND METHODS Thirteen patients with renal stones and concomitant urinary anomalies underwent laparoscopic stone surgery combined with anc...

BACKGROUND The aim of the study was to measure the content of methylated purines that appear as admixtures in uric acid stones. METHODS We analyzed urinary calculi from 48 residents of Western Pomerania who underwent surgery at the urology ward in Szczecin. Stone samples were dissolved in 0.1 mol/L NaOH. Extracts were diluted in 50 mmol/L KH(2)PO(4) and analyzed by reversed-phase HPLC with ul...

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...

PURPOSE To determine the efficiency of slow delivery rate of shockwaves (SW) on stone fragmentation and treatment outcomes in patients with renal and ureteral calculi. PATIENTS AND METHOD Using the Siemens Lithostar Multiline, we treated 843 patients (229 renal and 614 ureteral stones) at a fast delivery rate (120 SW/min, between October 2003 and August 2006), 448 patients (139 renal and 309 ...

PURPOSE The aim of this study was to evaluate the biochemical stone composition in general population of Qom province, central Iran, and its relationship with high tap water hardness. MATERIALS AND METHODS In a prospective study, from March 2008 to July 2011, biochemical analysis of urinary stones in patients living in Qom province for at least 5 years was performed. Stones were retrieved by ...

conclusions: administration of α-1a-specific blocker reduced analgesic dosage and colic episodes and rate of adverse effects after ureteroscopic lithotripsy of lower ureteral stones and decreased gravel expulsion time after ursl. results: the results showed that tamsulosin treatment group had low expulsion time (p = 0.011), low urinary tract symptoms, least analgesic needs and low adverse effec...

Bladder stones in men are thought to be almost exclusively due to outflow obstruction. We studied the incidence of operations for urinary outflow obstruction and bladder stone to establish the relationship between these two conditions in Kelantan. In only 48 (31%) of 154 men undergoing removal of bladder stones was a procedure for outflow obstruction performed. Thus the remaining 69% had no cli...

Urolithiasis is common and is becoming more prevalent worldwide. This study assessed the chronological trends in clinical and urinary metabolic features over 20 years in Korean urolithiasis patients. We performed a retrospective analysis of 4,076 patients treated at our clinic from 1996 to 2015. Urinary metabolic data and stone analysis data were available for 1,421 and 723 patients (34.9% and ...
