BACKGROUND Ureteropelvic junction obstruction (UPJO) is one of the most common causes of urinary tract obstruction in children. Several methods are used to diagnose upper urinary tract obstruction including renal ultrasonography (US), intravenous pyelogram (IVP), diuretic renography (DR), magnetic resonance urography (MRU) and antegrade or retrograde pyelography. Nowadays it is suggested to use...

  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...

The optimal management of children with antenatally diagnosed unilateral hydronephrotic kidneys is unclear. We have monitored renal function and drainage using 99mTc-DTPA renography in 77 children with such kidneys presenting at 1-14 mo of age with the aims of throwing light on the natural history of the condition and evaluating the response of the kidney to pyeloplasty. Since management was in...

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 month...

  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 contrastin...

Objective: Congenital hydronephrosis is a common prenatally diagnosed anomaly associated with an incidence of approximately 0.5-1% in newborns. The purpose of this study was to clarify the value of 99 m diethylenetriamine pentaacetic acid (99mTc-DTPA) in the assessment of renal function impairment of pediatric hydronephrosis. Methods: A total of 48 children with unilateral ureteropelvic junctio...

OBJECTIVE To discuss the main steps of renographic technique and underline some pitfalls related to the acquisition, processing and interpretation of diuretic renography, an important method for guiding the management of asymptomatic congenital hydronephrosis. METHODS Despite guidelines and consensus protocols, renographic procedures differ among centres, causing difficulties in comparison an...

Objective: To evaluate the improvement of renal function after pyeloplasty measured by 99mTc-DTPA renography. Materials and Methods: This hospital based quasi experimental study was done in department urology, National Institute Kidney Diseases Urology (NIKDU) Bangladesh Research Rehabilitation for Diabetes, Endocrine Metabolic Disorders (BIRDEM) from July 2014 to December 2020. Sixty patients ...
