Four neonates with abdominal masses following adrenal hemorrhages were investigated by renal scintigraphy. Characteristic photon-deficient lesions were noted in the suprarenal areas during the phase of whole-body radionuclide distribution.
Subchronic treatment with phenobarbital induces renal cortical microsomal monooxygenase activities (e.g., ethoxycoumarin O-deethylase, benzphetamine N-demethylase and arylhydrocarbon hydroxylase) and cytochrome P-450 content in rabbits but not in rats. The mechanism responsible for this species-specific difference in renal cortical enzyme induction remains unknown, but may be the result of diff...
BACKGROUND Renal artery stenosis (RAS) is a known cause of hypertension and ischemic nephropathy. Stenting of the artery is a valid approach, in spite of cases of unexpected adverse evolution of renal function. METHODS In this study, 27 patients with unilateral RAS were subjected to stenting and followed for a period of one year, while 19 patients were observed while on medical treatment only...
BACKGROUND Acute pyelonephritis often leaves children with permanent renal scarring. AIMS To compare the prevalence of scarring following initial treatment with antibiotics administered intravenously for 10 or three days. METHODS In a prospective two centre trial, 220 patients aged 3 months to 16 years with positive urine culture and acute renal lesions on initial DMSA scintigraphy, were ra...
BACKGROUND High-grade blunt renal trauma has been treated by arterial embolization (AE). However, it is unknown whether AE preserves renal function, because conventional renal function tests reflect total renal function and not the function of the injured kidney alone. Dynamic scintigraphy can assess differential renal function. METHODS We performed AE in 17 patients with grade-4 blunt renal ...
Introduction: The aim of this study was to evaluate the effect of successful kidney transplantation (KT) on myocardial perfusion and left ventricular function by both qualitative (visual) interpretation and semiquantitative parameters, using myocardial perfusion scintigraphy with gated-single photon emission computed tomography (gated-SPECT) in patients suffering from end-stage renal disease. ...
Context.— Renal malignancies can be divided into cortical- and medullary-based tumors, the latter of which classically infiltrate renal parenchyma by extending between nonneoplastic structures. Although high-grade cortical tumors rarely exhibit same growth pattern, infiltrative morphology should elicit a differential diagnosis to considered in each case. However, these diagnoses challenging dis...
