BACKGROUND Conventional X-ray urography is one of the basic imaging techniques in urinary tract diseases in children. CT urography (CTU) employing standard Filtered Back Projection (FBP) reconstruction algorithms is connected with higher radiation dose. Advanced iterative reconstruction techniques enable lowering the radiation dose to the level comparable(More)
UNLABELLED There are many controversies related to diagnosis of significant urodynamically uretropelvic junction obstruction (UPJO) in children with congenital hydronephrosis (CHN). We compared three imaging methods: ultrasonography (US), diuretic renography (DR) and urography. We studied 23 children with CHN in mean age 6.8 +/- 10.4 months. Despite similar(More)
In the paper 15 children are presented with terminal renal insufficiency in whom 17 arteriovenous fistulas were created between brachial artery and basilic vein displaced subcutaneously within the arm. Operational technique and obtained results are discussed with particular stress put on the usefulness of this type of fistula for children requiring(More)
BACKGROUND Extravaginal testicular torsion (ETT), also called prenatal or perinatal, occurs prenatally and is present at birth or appears within the first month of life. It has different etiology than intravaginal torsion, which appears later in life. Testicular torsion must be taken into consideration in differential diagnosis of acute scrotum and should(More)
BACKGROUND Hepatic portal venous gas (HPVG) is a rare imaging finding in children. It can be an important manifestation of severe diseases such as necrotizing enterocolitis (NEC) in neonates or bowel wall rupture in older children. However, there are many other diseases presenting with HPVG that do not necessarily require a surgical intervention. CASE(More)
BACKGROUND Hydronephrosis is the one of the most common congenital abnormalities of urinary tract. The left kidney is more commonly affected than the right side and is more common in males. AIM OF THE STUDY To determine the role of ultrasonography, renal dynamic scintigraphy and lowerdose computed tomography urography in preoperative diagnostic workup of(More)
Introduction of iterative reconstruction technique in modern computed tomography allowed to reduce the radiation dose and to extend indications for computed tomography urography in children. We describe the case of boy with congenital anomalies in urinary tract including bilateral double collecting system, dilatation of double collecting system in the right(More)
KEY CLINICAL MESSAGE The most common etiologies of acute scrotum in boys <1 year of age are torsion of the testis or an appendix, urogenital anomalies, and epididymitis. We report an infant with recurrent epididymitis associated with single-system ectopic ureter opening into the seminal vesicle and dysplastic right kidney. Treatment included(More)
BACKGROUND Calyceal diverticula are rarely diagnosed in children. They can mimic other renal cystic lesions and correct diagnosis can be difficult to establish. Connection between fluid collection and collecting system confirmed by imaging studies is the key diagnostic finding. CASE REPORT In this report we present a case of pediatric patient with(More)
BACKGROUND The differential diagnosis of adrenal pathology depends on the child's age and imaging findings. CASE REPORT Three children without clinical symptoms of neoplasm, with an adrenal lesion discovered on diagnostic ultrasound imaging. Laboratory tests for neoplasm were negative. The final diagnosis was based on histopathological examinations after(More)
