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 ...

The purpose of this study was to develop a method based on artificial neural networks for interpretation of captopril renography tests for the detection of renovascular hypertension caused by renal artery stenosis and to assess the value of different measurements from the test. A total of 250 99mTc-MAG3 captopril renography tests were used in the study. The material was collected from two diffe...

Technetium-99m-diethylene triamine pentaacetic acid ((99m)Tc-DTPA) has been widely used after (131)I-ortho-hippurate ((131)I-OIH) for renography and to test renal function. Only a few reports refer to normal values range of (99m)Tc-DTPA renography half maximum time (HMT). We have measured the normal value range of (99m)Tc-DTPA renography HMT in our department, of 433 healthy kidney donors fro...

OBJECTIVE The purpose of this study was to evaluate split renal function, estimate single-kidney renal function, and identify cause of obstruction in patients with ureteropelvic junction (UPJ) obstruction by using contrast-enhanced dynamic MR renography (MRR). MATERIALS AND METHODS Seventeen patients with UPJ obstruction underwent MRR and diuresis nuclear renography. Nuclear renography assess...
