RCT: Prevention of contrast-induced nephropathy with sodium-potassium citrate

Source: Eur Heart J Area: News Contrast-induced nephropathy (CIN) is a frequent complication of many radiological procedures involving the application of contrast media. A number of methods have been proposed for the prevention of CIN, including the alkalinisation of urine. Sodium-potassium (Na/K) citrate is a well-known agent for urine alkalinisation, and is mainly administered to patients with kidney stones. It has not been studied in the prevention of CIN.   Researchers tested the hypothesis that alkalinisation of urine, using Na/K citrate, reduces the frequency of contrast nephropathy in patients after coronary angiography. They conducted an RCT in 202 patients who were randomised to the Na/K citrate or to the control group.   Patients randomised to Na/K group received hexakalium-hexanatrium-trihydrogen-pentacitrat (5 g diluted in 200 mL of water). Urinary pH was measured immediately before coronary angiography, i.e. 1 hour after the administration of the medicine. Four hours after the ...

We describe a case of a 65-year-old woman undergoing hemodialysis treatment since 1986 after a bilateral nephrectomy due to complicated nephrolithiasis. Her last access, two Tesio® tunneled cuffed catheters implanted via the right internal jugular vein functioned correctly for 14 years without complications, and so, was not replaced in the meantime. She was referred to our hospital due to a rupture in a catheter lumen, which was corrected conservatively by creating a more proximal tunnel and excising the affected area. A few weeks later, a new rupture in the same lumen was identified, so the catheter was replace...

We report the case of a 60-year-old Caucasian man treated 1 month before at another center with primary coronary angioplasty and stenting of the ramus intermedius for coronary syndrome. Coronary angiography showed a critical stenosis of the left main coronary artery as well as critical calcified stenosis of the left anterior descending artery and the diagonal branch. Coronary calcification was treated with rotational atherectomy that preceded the angioplasty and stenting. Because of persistence of the symptomatology, coronary angiography was repeated 1 month later and showed a critical calcified restenosis of the ramus int...

CONCLUSIONS AND CLINICAL RELEVANCE 2 angiographic catheters were identified that could be successfully, blindly advanced in a retrograde direction into the urinary bladder of healthy sexually intact male goats. Such catheters may be useful for determining urethral patency, emptying the urinary bladder, and instilling chemolysing agents in goats with clinical obstructive urolithiasis.

ç E Abstract Eosinophilic myocarditis (EM) is a rare form of myocarditis that usually presents with heart failure due to eosinophilic infiltration. EM is often a component of hypereosinophilic syndrome (HES). HES is a rare disorder characterized by persistent, marked eosinophilia combined with organ system dysfunction. A 38-year-old man was admitted to emergency services with left inguinal pain and fever, and was hospitalized with diagnosis of nephrolithiasis and urinary tract infection. Intravenous antibiotic therapy of 3 grams meropenem per day and analgesic of 50 mg pethidine per day were administered. ...

Dual energy CT has emerged as a topical scanning technique with advances in MDCT technologies which enable near simultaneous acquisition of scan data at two separate kV or energy levels. Major applications in kidney stone characterization, pulmonary CT angiography, gout evaluation and differentiation of blood and contrast media have been reported. Due to differences in acquisition techniques for dual energy CT between different vendor offerings, it is important to keep in mind that these variations have important implications on associated radiation doses.

Percutaneous nephrolithotomy (PCNL) is a commonly used minimally invasive option for the management of complex renal stones. Although proven to be safe and effective, iatrogenic vascular complications requiring angioembolization (AE) remain a real concern. AE is a sensitive test to evaluate hemorrhage, however, up to 11% of patients are reported to have a negative study. We investigate factors associated with negative findings at time of renal angiography in patients with post-PCNL hemorrhage.
