BACKGROUND Optimum management to prevent recurrent kidney stones is uncertain. PURPOSE To evaluate the benefits and harms of interventions to prevent recurrent kidney stones. DATA SOURCES MEDLINE, Cochrane, and other databases through September 2012 and reference lists of systematic reviews and randomized, controlled trials (RCTs). STUDY SELECTION 28 English-language RCTs that studied tre...

We report a case of a kidney-transplanted patient with urolithiasis treated with mini-percutaneous laser lithotripsy. The patient presented with renal dysfunction and graft hydronephrosis. Diagnostic procedures revealed ureterolithiasis as a cause of obstruction, and percutaneous nephrostomy was inserted as a temporary solution. Before surgery, the stone migrated to the renal pelvis. Mini-percu...

Interstitial Randall's plaques and collecting duct plugs are distinct forms of renal calcification thought to provide sites for stone retention within the kidney. Here we assessed kidney stone precursor lesions in a random cohort of stone formers undergoing percutaneous nephrolithotomy. Each accessible papilla was endoscopically mapped following stone removal. The percent papillary surface area...

introduction: the prevalence of rare bleeding disorders, including combined factor v+viii deficiency are higher in iran than in developed countries. there are only a few reports which have been written concerning kidney transplantation in the patients suffering from these disorders. case report: a 22-year old girl, with a known case of combined factor v+viii deficiency, a history of bladder sto...

renal actinomycosis is a rare infection, and actinomycosis mostly acts as a normal flora in mouth, colon and vagina. we present a case of 56 years old man, who referred to our center for renal transplantation with kidney stone and diagnosed  with renal actinomycosis.  this case has risen possibility of rare infection that can be considered in the setting of renal transplantation.

Numerical simulations are used to evaluate the damage potential of the shock-induced collapse of a pre-existing gas bubble near a rigid surface. In the context of shock wave lithotripsy, a medical procedure where focused shock waves are used to pulverize kidney stones, shock-induced bubble collapse represents a potential mechanism by which the shock energy directed at the stone may be amplified...

Objective: Silent and not yet discovered stones of the upper urinary tract are potentially dangerous since in due course they may cause infection, obstruction and renal damage. The aim of this study was to determine the incidence of such silent kidney stones in a representative Pakistani population of the Karachi area. Subjects and Methods: We studied 201 consecutive subjects at our hospital wh...

The effect of combining therapy with hydrochlorothiazide, allopurinol and systemic alkalization for urolithiasis with lower urinary pH was examined. A total of 90 patients were followed up for 1 to 3 years, the average follow up period being 18 months. The total stone disappearance rate was 60% (kidney stone), 74% (ureter stone) and 20% (bladder stone). Large amounts of thiazide diuretics, pota...

Emphysematous pyelonephritis (EPN) is an acute necrotizing and suppurative infection of the kidney parenchyma. It is defined by the presence of gas within the kidney parenchyma and surrounding tissues. This rare condition is usually seen in diabetic or immunocompromised adults. In this paper, we report four cases of emphysematous pyelonephritis (including two diabetic patients) managed by broad...
