A 10-year-old boy with a history of bloody discoloration of urine following recent appendectomy was referred to our department for urinary leakage/fistula evaluation. A renal Technetium-99m-L,L-ethylenedicysteine (99mTc-EC) scintigraphy was performed. After injection of radiotracer, a focus of activity appeared in the supralateral part of the right kidney which was confirmed as accum...
INTRODUCTION. Urinary tract infection is the most common serious bacterial infection in children. The aim of this study was to compare the value of different laboratory and imaging techniques in detecting renal involvement in acute pyelonephritis. MATERIALS AND METHODS. In a cross-sectional study of patients 1 month to 14 years of age diagnosed with urinary tract infection were examined with sy...
Technetium-99m-mercaptoacetyltriglycine (99mTc-MAG3) was tested in 82 hypertensive patients submitted to renal scintigraphy 1 hr after oral premedication with 50 mg of Captopril. Baseline studies were obtained only for those patients showing abnormal findings in the provocative study. All patients underwent renal arteriography. Sensitivity and specificity for the detection of renal artery steno...
PURPOSE The purpose of this study was to evaluate the efficacy of retroperitoneal laparoscopic ureterolithotomy for the management of large proximal ureteric stones and the impact of this treatment on postoperative renal function. METHODS The data of 12 patients (7 men and 5 women; mean age, 68.5 ± 8.9 years) with large pyeloureteral junction (2 cases) and upper ureteral (10 cases) stones (25...
introduction: clinical radiation nephropathy can result in considerable morbidity and/or mortality. renal tolerance (td5/5) has been stated to be 20 gy when irradiation has been delivered to both kidneys in 3-5 weeks. therefore to minimize renal toxicity in these patients, localization and shielding of the kidneys are essential. this study was carried out to evaluate the role of 99mtc-dtpa rena...
BACKGROUND Radiation-induced nephropathy is still dose limiting in radionuclide therapy of neuroendocrine tumors. We investigated the nephroprotective potential of the angiotensine converting enzyme inhibiting drug enalpril after [177Lu]-DOTATATE therapy in a murine model of radiation-induced nephropathy by renal scintigraphy. At first, the appropriate therapy activity to induce nephropathy was...
Getting rid of the tubes: An assessment of the retention of functionalized multi-walled carbon nanotubes (MWNTs) in the organs of mice was carried out using single photon emission computed tomography and quantitative scintigraphy (see scheme). Increasing the degree of functionalization on MWNTs enhanced renal clearance, while lower functionalization promoted reticuloendethelial system accumulat...
