Reliable differentiation between obstructive and non-obstructive hydronephrosis is decisive for the further therapeutic management in infants. The results of renal Doppler sonography were compared with diuretic radionuclide renography and with the follow-up results in 33 patients (range: 21 to 98 days). In Doppler sonography, a resistive index (RI) of > 0.9 was considered to be abnormal in the ...

Of 52 cases with 56 affected renal units having symptoms and signs suggestive of Ureteropelvic Junction Obstruction (UPJO) evaluated by conventional (F + 15) diuretic renography where frusemide is given 15 minutes post-injection of radiopharmaceutical m99TC.DTPA.F + 15, twelve (21%) showed a good clearance (group A), 16 (28%) showed partial (group B) and 28 (50%) a poor clearance pattern (group...

introduction: urinary obstructive disease is one of the most common disorders in urinary system. dilatation which is detected by sonography, is a key finding in obstruction in most of the cases, also could be found following surgery, lithotripsy and vesico–urethral reflux. radioistope diuretic washout renography is a useful method to differentiate mechanical and non mechanical obstruction. mate...

introduction: it has been suggested that calculation of differential renal function (drf) using 99mtc-dmsa may lead to overestimation of the function of an obstructed kidney. the aim of this study was to evaluate the effect of diuretic administration on the determination of drf using 99mtc-dmsa scintigraphy in patients with dilated pelvis. methods: thirty three patients, aged from 2 months to 6...

Purpose: We aimed to retrospectively compare the surgical and nonsurgical follow-up results of ureteropelvic junction obstruction without diuretic response. Methods: Twenty nine pediatric patients (10 Female (F), 19 Male (M); mean: 4.4 ± 3.96 years old, range: 0-15) without diuretic response were subject of this study. The diuretic renography, intravenous pyelography, voiding and ultrasonograph...

INTRODUCTION To observe the renal function recovery measured by diuretic renography in short and medium follow-up of patients with transperitoneal Anderson-Hynes laparoscopic pyeloplasty. MATERIAL AND METHODS WE PERFORMED A RETROSPECTIVE REVIEW FROM OUR SERIES OF LAPAROSCOPIC PYELOPLASTIES, AND WE APPLIED THE FOLLOWING SELECTION CRITERIA: 1) to have at least two MAG3 diuretic renography durin...

BACKGROUND The purpose of this study was to clarify the value of renal drainage half-time in the evaluation of pediatric hydronephrosis after dismembered pyeloplasty. METHODS We reviewed the records of 30 children who underwent dismembered pyeloplasty for unilateral ureteropelvic junction obstruction with no other associated urological abnormality. The follow-up duration was more than 5 years...

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...

Abstract Purpose The aim of this systematic literature review was to obtain an overview when administer the diuretics in relation radiopharmaceutical during a diuresis renography. Methods A search performed three different databases (Embase, PubMed/Medline and Cochrane Library) together with information specialist. question was: should be administered renography? Studies adults were included gu...

Urinary obstruction is a common cause of acute and chronic renal failure. The symptoms and signs of an obstructed kidney may vary from asymptomatic to severe acute pain. The diagnosis and management of a hydronephrotic kidney is not very difficult with ultrasonography, IVU, and diuretic renography. The approach to manage such patients has been rationalized after the advent of diuretic renograph...
