We evaluate the efficacy of ESWL in the management of calculi in patients with urinary diversion. We treated 5 patients who suffered from urinary lithiasis after urinary diversion post cistectomy. We managed the patients with extracorporeal shock wave lithotripsy in monotherapy with a Siemens Lithostar Modularis device. Mean stone size (long axis) was 1.95 cm (range 1 to 3.5 cm). The mean shock...

Kidney stone disease is a crystal concretion formed usually within the kidneys. It is an increasing urological disorder of human health, affecting about 12% of the world population. It has been associated with an increased risk of end-stage renal failure. The etiology of kidney stone is multifactorial. The most common type of kidney stone is calcium oxalate formed at Randall's plaque on the ren...

Urinary citrate (Ucit) protects against urinary stone formation. Acid base status and diet influence Ucit. However, the effect of demographics, diet, and glucose metabolism on Ucit excretion, urinary pH (U-pH) and net gastrointestinal alkali absorption (NAA) are not known. Twenty-four hour urine samples, blood glucose, creatinine, and cystatin C were obtained from non-Hispanic white sibships in...

Thirty-six patients with recurrent calcium oxalate nephrolithiasis were selected from the stone clinic. Fourteen were normocalcemic and had normal daily urinary calcium excretion. Among 22 patients with idiopathic hypercalciuria, 10 received thiazide diuretics for the prevention of new stone formation. Single-voided urine samples were collected at the outpatient clinic and 24-hour urine at the ...

OBJECTIVES To assess the value of dual-energy contrast-enhanced computed tomography (CT) imaging for the detection of urinary stone disease using dual-source CT. MATERIALS AND METHODS Forty consecutive patients (mean age 46.6 +/- 16.2 years, range 27-85 years) suspected of having urinary stone disease underwent dual-source CT of the urinary tract. A 3-phasic CT scan protocol consisting of a s...

BACKGROUND It is well known that many diseases may be associated with obesity resulting from an energy-rich diet, and that a westernized diet may increase the incidence of urinary stone formation. To evaluate degree of obesity, we investigated body mass index (BMI) in patients with calcium containing upper urinary stones and examined their blood with regard to lipid metabolism. METHODS Betwee...

abstract   background: hydronephrosis is the most common congenital condition that is detected by prenatal ultrasonography. moreover, the widespread use of prenatal ultrasonography results in an increased recognition of fetal hydronephrosis. prenatal hydronephrosis is diagnosed at an incidence of 1:100 to 1:500 by ultrasonographic studies. the presence of hydronephrosis is not synonymous with o...

A systematic clinical approach is required for the diagnosis and management of renal and ureteral stones. The presenting symptoms, past medical history, medications, and physical examination all provide clues to the diagnosis of urinary stones. In the acute setting, noncontrast helical computerized tomography has emerged as the first line imaging test for renal colic. More traditional imaging t...

a study was designed to evaluate the normal value of 24 hr urinary calcium levels in the city of yazd. the average urinary excretion of calcium in a sample of 329 persons randomly selected was 232 mg/day, while patients with a history of recurrent urolithiasis excreted 20x mg/day. there is evidence which shows that more important factors than the amount of urinary calcium exist which influence ...

PURPOSE Acute urinary retention in children is a relatively rare entity. There are a variety of causes that are poorly defined in the literature. We review our cases of acute urinary retention in children at three major pediatrics centers in Iran. MATERIALS AND METHODS Between 1996 and 2003, children (up to 14 years old) who had been referred due to acute urinary retention were examined. Urin...
