1. Differentiate genitourinary abnormalities associated with hydronephrosis detected on fetal ultrasonography. 2. Describe the type of fetal hydronephrosis that requires a complete uroradiologic evaluation. 3. Characterize the complete postnatal uroradiologic evaluation of significant fetal hydronephrosis. 4. Delineate the factor that sets the timetable for postnatal uroradiologic evaluation. 5...

UNLABELLED Numerous competing diagnostic modalities and the lack of data about therapeutic benefit result in controversy concerning the identification and treatment of renovascular hypertension. METHODS Meta-analyses were used to examine the cost efficacy of renovascular hypertension diagnosis and treatment. Sensitivity, specificity and predictive value were calculated for captopril renograph...

AIM Introduction and assessment of an obstruction score in patients with obstructive uropathy, based on a diuresis renography time-activity curve. METHODS Twenty-eight adults with unilateral pelviureteric junction obstruction were assessed by ultrasound scan, furosemide-enhanced intravenous urography and modified (F-15) 99mTc-DTPA diuresis renography. Renal unit drainage pattern was assessed ...

UNLABELLED Proposed renal hemodynamic mechanisms of captopril suggest that quantitation of renographic retention parameters should help identify patients suspected of having renovascular disease. The parenchymal mean transit time (MTT) is theoretically superior to other measures of retention, but data supporting its superiority are few. METHODS Two groups of subjects were studied with diethyl...

OBJECTIVE To compare ultrasound (US) scan and nuclear renography findings in patients who underwent pyeloplasty with and without pelvic reduction in a randomized prospective study. METHODS A total of 42 patients, all prenatally diagnosed with unilateral hydronephrosis, were included. Hydronephrosis was confirmed postnatally. Twenty patients were randomly selected to undergo pyeloplasty with p...

OBJECTIVE It has been advocated that a reduced injection volume with highly concentrated (1 M) contrast material can produce a sharper bolus peak and an increased intravascular first-pass gadolinium concentration when compared with the use of a lower concentration (0.5 M). A higher concentration would also cause a reduction in dose. The purpose of our study was to test the use of a low dose (0....
