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...
A 13-year-old girl with fused pelvic kidneys detected on ultrasonographic examination was referred to our department for a diuresis renography to assess urine drainage dynamics and exclude the possibility of urinary tract obstruction. Renal scan demonstrated fused pelvic kidneys functioning normally without obstruction. The authors present this case to demonstrate the diuresis renography findin...
To assess the influence of the ureter on renal washout during 99mTc-DTPA diuresis renography, ureteral images were reviewed in 42 children (median age: 5 mo) referred for hydronephrosis. Sixty-minute acquisitions were obtained in hydrated patients under bladder drainage. Furosemide was injected at 30 min. An abnormal ureter was defined as an intense and continuous image of greater than 10 min. ...
BACKGROUND Exercise-induced alteration in renal function has been described in patients with essential hypertension. The aim of our study was to assess the significance of adopting a supine posture and the degree of workload required to induce these changes in patients with essential hypertension. The second aim was to assess whether the severity of hypertension had any influence on the develop...
Our previous study investigated the effect of a single dose of NSAID diclofenac, which is the most commonly used to relieve kidney pain, on the renograms using radiopharmaceuticals. The objective of this study is to examine the effect of long-term use of diclofenac on renography. A baseline study (control) was done by injecting the rabbits Tc-DTPA and a renography was performed. Two days later ...
