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...

the common use of maternal ultrasonography has increased the apparent incidence of neonatal hydronephrosis. many of these cases are found to have partial obstruction at the ureteropelvic junction (upj). these patients are safely managed in our institution with careful observation and only occasionally require surgical intervention. the authors present two contrasting cases of suspected upj obst...

INTRODUCTION L,L-ethylenedicysteine (EC) is a new carrier of technetium Tc 99m (99mTc) with a lower affinity to plasma albumin in comparison with diethylenetriamine pentaacetic acid (DTPA). We compared 99mTc-EC scan with 99mTc-DTPA scan in diuretic renography for patients with obstructive uropathy. MATERIALS AND METHODS Thirty-three patients with upper urinary tract obstruction were randomly ...

PURPOSE To evaluate (99m)Tc-mercaptoacetyltriglycine diuretic renograms for diagnosing stomal obstruction in tubeless cutaneous ureterostomy. MATERIALS AND METHODS Cutaneous ureterostomy was performed in 29 patients (56 renal units) with a minimum follow-up period of 12 months. Stomal obstruction was evaluated with (99m)Tc-mercaptoacetyltriglycine diuretic renography 3 months after surgery. R...

Background: Diuretic renography using 99mTc-mercaptoacetyltriglycine (99mTc-MAG3) is a relatively non-invasive technique and has been increasingly used as reliable for the evaluation of kidney function in wide range disorders. Methods: In this retrospective study, we retrieved medical records patients referred to Radiology Department Radiology, King Abdulaziz Specialist Hospital, Taif, Saudi Ar...

A 2-year-old girl with recurrent urinary tract infection having slight left pelvicaliceal dilatation on her renal ultrasound underwent a Tc-99m DTPA diuresis renography. During the excretion phase, a prominent and persisting left pelvicaliceal stasis was noticed even after the diuretic injection. However, it disappeared simultaneously with an uncontrolled micturition. This patient is presented ...

OBJECTIVES Determine the efficiency of the Acucise catheter in the treatment of ureteropelvic junction (UPJ) obstruction. MATERIALS AND METHODS Between May 1997 and April 1999, 30 patients with primary or secondary ureteropelvic junction obstruction were treated using Acucise endopyelotomy catheter. The diagnosis was based on intravenous urography and diuretic renography. None of the patients...

Infantile hydronephrosis detected by ultrasonography poses a clinical dilemma on how to treat the condition. This article reports a retrospective study to evaluate infantile hydronephrosis due to suspected ureteropelvic junction (UPJ) obstruction by means of standardized diuretic renography and to speculate its usefulness for quantitative assessment and management of this condition. Between Nov...
