Recently, cases of urinary tract calculi causing hydronephrosis and postrenal renal failure associated with viral gastroenteritis were documented, yet few were related to norovirus. During norovirus gastroenteritis, observation of oliguria, aciduria, low FENa value, and elevation of blood or urinary uric acid level may necessitate clinical workout for nephrolithiasis.

Cholesteatoma of the urinary tract is a rare condition which can be diagnosed radiographically. The radiographic findings of stringy intraluminal defects or nodules that may lightly calcify or coalesce to form a discrete mass in association with calculi and/or obstruction are characteristic. A history of chronic urinary tract infection, renal colic, and desquamated epithelial cells in the urine...

The lifetime risk of developing genitourinary stone is 5-12%.  Males are more prone to calculus formation as compared females. data for the Indian population suggests that 12% people develop urinary calculi and half them end up with loss kidney functions. Symptomatic urolithiasis represents a common condition observed by surgeons urologists in an emergency setting. lower third/distal urete...

OBJECTIVE The objective of this study was to compare the efficacy of plain spiral computed tomographic (CT) scan with intravenous urography (IVU) in the evaluation of patients with suspected urinary calculi/obstruction. MATERIALS AND METHODS Twenty consecutive patients with acute signs of renal colic were prospectively examined with unenhanced spiral CT followed by an IVU within the same day....

Although routine screening for bladder cancer is not recommended, microscopic hematuria is often incidentally discovered by primary care physicians. The American Urological Association has published an updated guideline for the management of asymptomatic microscopic hematuria, which is defined as the presence of three or more red blood cells per high-power field visible in a properly collected ...

Sodium pyruvate, choreito (a herbal preparation), and urajirogashi (a herb) were added to a calcium-oxalate lithogenic diet (a glycolic-acid diet) to determine their effects in preventing lithogenicity. Male Wistar-strain rats which had been fed the glycolic-acid diet developed marked urinary calculi within 4 weeks. Rats in the groups fed a pyruvate diet had, however, almost no stones in the ur...

Urolithiasis is the term used to denote the formation of urinary calculi in animals including disease conditions that arise as a direct result. The terms urinary calculus and urolith on the other hand apply only to the actual calculi or uroliths formed in urolithiasis. In cattle, urinary calculi present in the bladder, on occasions enter and obstruct the urethra. This is the common form of obst...

Purpose: The aim of this study is to identify the risk factors for development of sepsis in patients with obstructive acute pyelonephritis (APN) associated with urinary tract calculi. Materials and Methods: Between January 2004 and December 2013, 73 patients with obstructive APN associated with upper urinary tract calculi were admitted to our institution. Medical records of 73 patients (14 men ...

We aim to find the risk factors that influence the formation of bladder calculi in patients with benign prostate hyperplasia (BPH) and to reduce the surgical intervention related to bladder calculi.Between January 2015 and October 2016, 332 patients with BPH underwent surgical therapy were retrospectively evaluated. Patients with BPH were categorized into 2 groups: 94 patients with bladder calc...

BACKGROUND Studies that evaluate the effect of age and gender on the stone composition are scarce. The aim of this study is to highlight the modification of epidemiological characteristics of this pathology according to patients' sex and age. PATIENTS AND METHODS We studied 1269 urolithiasic patients ranging from 6 months to 92 years old and known as having urinary stones (752 males and 517 f...
