CONTEXT: Spontaneous forniceal rupture is one of the possible complications of urolithiasis. The mechanism of forniceal rupture is not well explained in the literature. Most of the cases presented with sudden onset of acute renal colic and diagnosed by noncontrast CT (NCCT). Until now there is no solid consensus about the ideal management of such a condition. AIM: To study indications and validity of conservative management of spontaneous caliceal rupture. SETTINGS AND DESIGN: This is an observational prospective study...

PURPOSE: Recent reports support the use of renal ultrasonography (US) as the initial imaging study for the evaluation of patients with suspected renal colic. Urologists, however, often advocate for computed tomography (CT) to better define stone size and location, especially prior to proceeding with endourologic intervention. One concern with using US as the initial imaging study is that CT may be required at a later time, obviating the reduction in costs and radiation gained by using US...

Renal colic is a common clinical condition which is often investigated with a CT of the kidneys, ureters and bladder (CTKUB). Recent technological improvements have allowed a reduction in dose with the emergence of low-dose CTKUB (LD-CTKUB) techniques. The present meta-analysis aims to determine the diagnostic accuracy of LD-CTKUB in the diagnosis of clinically significant uroliths. A systematic review was performed using nine electronic databases from their dates of inception to May 2016. Inclusion criteria included studies reporting comparative outcomes using LD-CTKUB with a dose less than 3 millisieverts compared to an imaging gold standard or clinical and surgical evaluation...

OBJECTIVE: Urolithiasis of the transplanted kidney has an incidence of 0.2 to 1.7%, it increases the risk of infection in immunosuppressed patients and it can lead to ureteral obstruction that is often associated with deterioration of renal function. Urolithiasis of the transplanted kidney has different characteristics compared to the native kidney, due to the absence of innervation, which does not lead to colic pain. Percutaneous approach is an optimal choice in transplant patients. MATERIAL AND METHODS: Here we report our experience in two cadaveric transplant patients with urolithiasis...

BACKGROUND: Recommendations for the management of urolithiasis in primary care are lacking in France. The Delphi method was used to seek consensus from an expert panel regarding outpatient management of urolithiasis. METHODS: We gathered 25 French experts from five clinical specialties: general practice, urology, nephrology, emergency medicine and radiology. The first survey was formulated after an exhaustive literature review. At each of the three rounds, the experts were given the results of the previous round and were asked again to complete the survey...

CONTEXT: Low-dose computed tomography (CT) has become the first choice for detection of ureteral calculi. Conservative observational management of renal stones is possible, although the availability of minimally invasive treatment often leads to active treatment. Acute renal colic due to ureteral stone obstruction is an emergency that requires immediate pain management. Medical expulsive therapy (MET) for ureteral stones can support spontaneous passage in the absence of complicating factors...

INTRODUCTION: Computed tomography kidneys, ureter and bladder (CTKUB) is the accepted gold standard investigation for suspected renal colic. Dose considerations are particularly pertinent in the context of detecting urolithiasis given the high risk of disease recurrence, which can necessitate multiple radiological examinations over the lifetime of a stone-former. We performed a systematic review of the literature to see whether there was any evidence that reducing the effective radiation dose of a CTKUB compromised the diagnostic accuracy of the scan...

Kidney stones are very common and unfortunately do not spare the pregnant population. Anatomical and pathophysiological changes occur in the pregnant female that alter the risk for development of nephrolithiasis. Acute renal colic during pregnancy is associated with significant potential risks to both mother and fetus. Diagnosis is often challenging because good imaging options without radiation use are limited. Management of diagnosed nephrolithiasis is unique in the pregnant population and requires multi-disciplinary care...

The aim of this study was to assess demographic data, clinical presentation, metabolic features, and treatment in 76 children with urolithiasis presented from 2002 to 2011. Urolithiasis is responsible for 2.5/1,000 pediatric hospitalizations, with new cases diagnosed in 1.1/1,000 admissions. From the observed period, two-fold rise of incidence rate was observed. Compiling the data from other pediatric institutions in our country, we estimated present overall incidence rate in Croatia as 6.5/100,000 children under 18 years...

We describe an infant affected by adenine phosphoribosyltransferase (APRT) deficiency diagnosed at 18 months of age with a de novo mutation that has not been previously reported. APRT deficiency is a rare defect of uric acid catabolism that leads to the accumulation of 2,8 dihydroxyadenine (2,8-DHA), a highly insoluble substance excreted by the kidneys that may precipitate in urine and form stones. The child suffered from renal colic due to a stone found in the peno-scrotal junction of the bulbar urethra. Stone spectrophotometric analysis allowed us to diagnose the disease and start kidney-saving therapy in order to avoid irreversible chronic kidney damage...

Based on the prevalence of asymptomatic kidney stones (5% in our general ward, in accordance with the literature) the value of abdominal ultrasonography in the clinical assessment of a suspected kidney-colic is discussed. The eminent importance of the stone-analysis is emphasized. In addition, the most common causes of kidney stone formation (low urine output, mechanical urinary obstruction in the renal pelvis, hypercalciuria, hyperoxaluria, insufficient urinary citric acid excretion, hyperuricosuria) are highlighted...

The acute treatment of kidney stones (urolithiasis) addresses pain management and focuses on the effects of the morbidity associated with an obstructed renal system. Minimal fluid intake, resulting in decreased urine production and a high concentration of stone-forming salts, is a leading factor in renal calculi development. Radio-opaque calcareous stones account for 70% to 75% of renal calculi. Microscopic hematuria in the presence of acute flank pain is suggestive of renal colic, but the absence of red blood cells does not exclude urolithiasis...
