Background: Renal colic (RC) is one of the most common reasons for emergency department (ED) visits. Although RC is associated with high ambient temperature and with physiological changes that occur during fast, the literature onbetween Ramadan and RC incidence is scarce. Methods: We obtained health data of patients visited the emergency department (ED) of a large tertiary center during the years 2004-2015, with a primary diagnosis of RC. To estimate the association of RC and Ramadan, we utilized bi-weekly RC incidence Poisson models adjusted for ambient temperature and seasonality in two ethnic groups residing in the region: Muslims and Jews...

Chyluria is the passage of chyle in the urine. The cause seems to be the rupture of retroperitoneal lymphatics into the pyelocaliceal system, giving urine a milky appearance. This communication is caused by the obstruction of lymphatic drainage proximal to intestinal lacteals, resulting in dilatation of distal lymphatics and the eventual rupture of lymphatic vessels into the urinary collecting system.This condition, if left untreated, leads to significant morbidity because of hematochyluria, recurrent renal colic, nutritional problems due to protein losses and immunosuppression resulting from lymphocyturia...

INTRODUCTION: Several studies have examined the link between temperature or monthly-seasonal variations and urolithiasis. The majority of these studies have demonstrated a link between higher ambient monthly temperatures and the incidence of renal colic and kidney stone disease (KSD). However a worldwide trend on this association has not been explored and we perform a systematic review to examine the effect of seasonal variations on renal colic and KSD. MATERIALS AND METHODS: A systematic review of literature over a 26-year period (1990-2017) was conducted on all studies reporting on the effect of seasonal variations and its link to KSD...

A shortcut review was carried out to establish whether intravenous lidocaine is effective in the management of renal colic. Two studies were directly relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these studies are tabulated. The clinical bottom line is that intravenous lidocaine may be of some benefit in renal colic. However, there are other maybe more effective drugs available.

Crystals can trigger a wide range of kidney injuries that can lead to acute kidney injury, chronic kidney disease, renal colic or nephrocalcinosis, depending on the localization and dynamics of crystal deposition. Studies of the biology of crystal handling by the kidney have shown that the formation of different crystals and other microparticles and the associated mechanisms of renal damage share molecular mechanisms, such as stimulation of the NLRP3 inflammasome or direct cytotoxicity through activation of the necroptosis signalling pathway...

BACKGROUND: Ureteric colic is the most common symptom of lithiasis. It is caused by the presence of stones accumulated in the renal papillae. These stones often migrate down the ureter, causing a ureteric colic, characterized by a severe pain in the lumbar region. The aim of this study was to compare the use of ketorolac and nifedipine vs. ketorolac and tamsulosin for the medical treatment of pain caused by stones in the lower ureter. METHODS: Longitudinal study of 150 patients of 21-years or older with stones in the lower third of the ureter...

PURPOSE: Recent reports support renal ultrasound as the initial imaging study to evaluate patients with suspected renal colic. However, urologists often advocate for computerized tomography to better define stone size and location, especially before proceeding with endourological intervention. One concern with using ultrasound as initial imaging is that computerized tomography may be required later, obviating the reduction in costs and radiation gained by using ultrasound. MATERIALS AND METHODS: We retrospectively reviewed the electronic health records of 10,680 episodes of stone disease in a total of 7,659 patients who presented to the emergency department or walk-in clinic with a chief complaint or visit diagnosis of urolithiasis from 2009 to 2015 at a single institution...

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...

BACKGROUND: Ketorolac tromethamine is a non-steroidal anti-inflammatory drug (NSAIDs) that is widely used in the emergency department (ED) for the treatment of moderate-to-severe pain. Ketorolac, like other NSAIDs, exhibits an analgesic ceiling effect and previous research suggests that 10 mg is possibly the ceiling dose. Do the patterns of ketorolac dosing by emergency physicians follow its analgesic ceiling dose? METHODS: This was a single center retrospective, descriptive study to characterize patterns of ketorolac administration in ED patients...
