BACKGROUND The diagnostic value of non-invasive methods for diagnosing renal artery stenosis in patients with renal insufficiency is incompletely known. METHODS Forty-seven consecutive patients with moderately impaired renal function and a clinical suspicion of renal artery stenosis were investigated with computed tomography angiography (CTA), gadolinium-enhanced magnetic resonance angiograph...

The optimal management of children with antenatally diagnosed unilateral hydronephrotic kidneys is unclear. We have monitored renal function and drainage using 99mTc-DTPA renography in 77 children with such kidneys presenting at 1-14 mo of age with the aims of throwing light on the natural history of the condition and evaluating the response of the kidney to pyeloplasty. Since management was in...

INTRODUCTION The management of neonates with congenital hydronephrosis (CHN) diagnosed antenatally is still controversial. MATERIALS AND METHODS A prospective study was performed in all newborn infants with CHN born over a 2-year period in order to identify which neonates require a full radiologic investigation including investigation with invasive tests such as voiding cystoureterography (VC...

OBJECTIVE The present study examines whether or not baseline and acetazolamide (ACZ) Tc-99m MAG3 renography can assess renal blood flow reserve. METHODS Renography proceeded for 50 min after sequential injections of 370 MBq Tc-99m MAG3 for baseline renography and 10 min after a 1,000 mg injection of ACZ for ACZ renography. Effective renal plasma flow of renal cortex (cERPF) in each kidney and...

Renal imaging with radioisotopes, or renal scintigraphy, allows the quantitative evaluation of renal function and urodynamics. Measurement of renal function provides essential information in various situations of clinical practice. Angiotensin-converting enzyme inhibitor renography makes it possible to detect patients with renovascular hypertension. Diuresis renography aids in differentiating u...

BACKGROUND Noninvasive cost-effective screening of hypertensive patients for renovascular hypertension is a desirable approach to a rare disorder. Currently many patients are screened with angiography, which is both invasive and expensive. METHODS A MEDLINE search from 1985 through July 1994 using the key words "renovascular hypertension," "noninvasive," "screening" generated 16 references. W...
