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...

Objective(s): Renography is used for the diagnostic evaluation of pediatric patients with a suspected obstruction of urinary tract or impaired renal function. The recommended dose for children have been released by the European Association of Nuclear Medicine, Society of Nuclear Medicine and Molecular Imaging, and Japanese Society of Nuclear Medicine. Since acquisition counts in dynamic scintig...

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...

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...

Isotope renography has been carried out in 32 babies with neurogenic bladder due to spina bifida or with other urological lesions. The tracings can be interpreted according to the standards applicable to renography in older children. Comparison of renography and intr...

renal artery stenosis (ras) is the most common cause of secondary hypertension. preliminary data indicate that aspirin renography with hippurate may be more sensitive for detection ras. in this study 20 patients with known or suspected ras underwent aspirin renography (20 mg/kg orally 1 hour before injection of radiotracer) and captopril renography (50 mg orally) with 99mtc-dtpa. renal angiogra...
