[Influence of the background activity region selection on the measurement of glomerular filtration rate using the Gates method].

Background/aim: The most frequent method for the assessment of glomerular filtration rate GFR) in clinical practice is clearance of creatinine, clearance of chromium-51 radiolabelled ethylene diamine tetraacetic acid (51Cr-EDTA) and clearance of technetium-99m radiolabelled diethylene triamine pentaacetic acid (99mTc-DTPA). The Gates method for glomerular filtration rate assessment is based on distribution of 99mTc-DTPA in the kidney 2-3 minute after its applying. Calculation of GFR is corrected for the background and depth of the kidney and finally expressed as a percentage of the net injected counts.

Impact of micturating cystourethrography and DMSA renal scintigraphy on the investigation scheme in children with urinary tract infection.

Objective: The relationships among urinary tract infection (UTI), vesicoureteral reflux (VUR), and permanent renal damage in children are not fully understood. The aim of this study was to evaluate the incidence of renal scarring in children with a history of UTI and to determine the change in the probability of permanent renal damage owing to the presence of VUR documented on micturating cystourethrography (MCU).

Methods: We analyzed 201 children (400 renal units, two children with solitary kidney).

99mTc-MDP bone scintigraphy in the diagnosis of stress fracture of the metatarsal bones mimicking oligoarthritis.

Background: Stress fractures are the injuries of soft tissues and bones caused by intensive and repeated stress on a bone. Repeated submaximal stress disturbs the balance between the processes of bone production and resorption that results in fracture.

Case Report: We presented a case of a patient with stress fracture of metatarsal bone.

Technetium-99m-dimercaptosuccinic acid renal scintigraphy in children with urinary tract infections.

The aim of this study was to determine the incidence of abnormal dimercaptosuccinic acid-Tc-99m ((99m)Tc-DMSA) renal scintigraphy findings in children with culture proved urinary tract infection (UTI) with or without vesicoureteral reflux (VUR). (99m)Tc-DMSA renal scintigraphy was performed in 343 children with culture documented UTI (247 girls and 96 boys) aged from three months to 14 years (middle age of 4.82 years).

[Renal scintigraphy in children with urinary tract infections].

Background/aim: To determine the incidence of abnormal Technetium Tc 99m Dimercaptosuccinic Acid (Tc99m DMSA) renal scintigraphy findings in the children with urinary tract infection (UTI), and to evaluate the difference between the children with UTI and vesico-ureteral reflux (VUR), and the children with UTI without VUR.

Methods: Tc99m DMSA renal scintigraphy was performed in 170 children with UTI, mean age 7.07 years (1 month to 14 years, 137 were girls and 33 were boys).
