[Metal objects in the MR]

VÁRALLYAY György

[During magnetic resonance imaging the patient is exposed to three different types of electromagnetic radiation: static magnetic field, gradient or time varying magnetic fields and radiofrequency electromagnetic fields. The potential risks associated with performing MRI in patients with ferromagnetic implants, materials, or devices are related to the possibility of movement or dislodgement, to the induction of electrical currents and to the heating. The majority of metallic implants are... tovább »

[Treatment of ureter stenosis of the transplanted kidney using invasive radiological methods]

DOROS Attila, WESZELITS Viola, PUHL Mária, RUSZ András, JANSEN Judit

[INTRODUCTION - Stenosis, occlusion and necrosis of the ureter after kidney transplantation occur in 2-13%. The therapeutic choices are surgery or minimally invasive endourological and percutaneous procedures. We analysed our therapeutic plan and results using percutaneous dilatation and stenting. PATIENTS AND METHODS - The patients after kidney transplantation are regularly examined by ultrasound. In cases of suspected obstruction we perform scintigraphy and CT-urography, and if indicated, we... tovább »

[The role of the mechanical lithotripsy for the treatment of ”difficult” common bile duct stones]

OROSZ Péter, NAGY György, SÜMEGI János, JUHÁSZ László

[INTRODUCTION - Present work aimed to identify some predictors of success or failure (gender, age, number and size of stones, presence of periampullary diverticula and jaundice) in mechanical lithotripsy. PATIENTS AND METHODS - 7998 endoscopic retrograde cholangio-pancreatographies, 2430 endoscopic sphincterotomies and 1205 bile duct stone extractions were performed between 1981 and 2000 years. In 159 patients - because of failure of standard techniques - mechanical lithotripsy was attempted... tovább »
