UNLABELLED Renal length measurements are used in evaluating several abnormalities of the pediatric genitourinary tract. This study assesses reproducibility of renal length measurements obtained with 99mTc-dimercaptosuccinic acid (DMSA) SPECT. METHODS The lengths of 98 kidneys of 51 children (age range, 1-16 y; mean age, 5.4 y) who underwent 99mTc-DMSA SPECT were measured independently by 2 ob...

A 14-year-old boy presented with asymptomatic right hydronephrosis detected on routine yearly ultrasound examination. Previously, he had at least two normal renal ultrasonograms, 4 years after remission of acute myeloblastic leukemia, treated by AML-BFM-93 protocol. A function of the right kidney and no damage on the left was confirmed by a DMSA scan. Right retroperitoneoscopic nephrectomy reve...

UNLABELLED (99m)Tc-Dimercaptosuccinic acid (DMSA) scintigraphy is a frequently used diagnostic test to assess the presence and severity of cortical damage. The aim of this study is to investigate the variability in the interpretation of (99m)Tc-DMSA scans, evaluate the usefulness of oblique images, and assess their impact on scan interpretation. METHODS Two experienced nuclear medicine physic...

BACKGROUND This study was undertaken to determine the incidence of urinary tract infection (UTI) and the frequency of anatomical abnormalities in newborns with unexplained jaundice and to find out if there is any correlation between bilirubin level and renal damage. METHODS We studied 462 full-term neonates for UTI. They were aged 3-25 days, with either high (>10 mg/dL) or prolonged (>10 days...

PURPOSE To identify the fetal stem cell (FSC) response to maternal renal injury with emphasis on renal integrity improvement and Y chromosome detection in damaged maternal kidney. MATERIALS AND METHODS Eight non-green fluorescent protein (GFP) transgenic Sprague- Dawley rats were mated with GFP-positive transgenic male rats. Renal damage was induced on the right kidney at gestational day 11. ...

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...

CONTEXT AND OBJECTIVE Studies using radionuclides are the most appropriate method for estimating renal function. Dimercaptosuccinic acid chelate labeled with technetium-99m (99mTc-DMSA) is the radiopharmaceutical of choice for high-resolution imaging of the renal cortex and estimation of the functional renal mass. The aim of this study was to evaluate a simplified method for determining the abs...

PATIENTS AND METHODS Thirty operated patients of myelodysplasia were clinically evaluated for the age at presentation, the extent of lesion and neurological deficit. Urological assessment was done with urine cultures, serum creatinine, radiological (ultrasound of kidney, ureters and bladder, voiding cystourethrogram) and urodynamic (water cystometry) parameters. An objective scoring for bladder...
