This study aimed to investigate the overall cumulative exposure-response and the lag response relationships between daily temperature and urolithiasis presentation in Seoul. Using a time-series design and distributing lag nonlinear methods, we estimated the relative risk (RR) of urolithiasis presentation associated with mean daily temperature, including the cumulative RR for a 20 days period, a...

Dear Editor, We read with interest the article “Role of high-dose hydrochlorothiazide in idiopathic hypercalciuric urolithiasis of childhood” by Naseri and Sadeghi.1 They used high-dose hydrochlorothiazide (1 mg/ kg/d to 2 mg/kg/d) in hypercalciuric children and described that no study has addressed whether low doses of thiazides have a hypocalciuric effect, especially in children.1 We recently...

BACKGROUND Emphysematous pyelonephritis is a severe infection of the kidney associated with formation of gas in the renal parenchyma and/or collecting system. The purpose of this study was to evaluate outcomes of patients with emphysematous pyelonephritis in a contemporary cohort and to evaluate the impact of urolithiasis on disease severity. METHODS A search of all imaging reports at Univers...

Urolithiasis is a multifactorial disease with high incidence and recurrence rate, characterized by formation of solid deposits in the urinary tract. The most common type these stones are calcium oxalate stones. Calcium crystals can, hyperoxaluric states, interact renal epithelial cells, causing injury to epithelia. Pathogenesis urolithiasis widely investigated, but underlying mechanisms still n...

In small ruminants especially in caprine breeds clinical obstructive urolithiasis is most frequently seen in young males that have been castrated at an extremely young age because of marketing to the pet market rather than the production market. The stones can be composed of phosphate and calcium salts: calcium phosphate (apatite), magnesium ammonium phosphate (struvite), calcium carbonate, cal...

The authors report a case of swine urolithiasis caused by improper administration of sulfamonomethoxine and which was diagnosed by examination of urinary sediments and analyzing the composition of the uroliths. The chemical composition of urinary calculi obtained from affected pigs with urolithiasis was further confimed as sulfamonomethoxine by fourier transform infrared (FTIR). It is suggested...

Metabolic causes such as hypercalciuria, urinary tract infection, and obstruction are the most common aetiologies of urolithiasis, and drugs, although important in this regard, are rarely the cause of urolithiasis. Administration of one of these drugs, ceftriaxone (CTX), has been associated with biliary pseudolithiasis in adult and paediatric patients, and rarely may cause urolithiasis. Several...
