AIM To evaluate abdominal adipose tissue accumulation in obese children by ultrasound measurement and compare with the elastic properties of the abdominal aorta. CHILDREN AND METHODS A total of 56 obese children and a control group of 30 non-obese children had an ultrasound examination for measurements of thickness of visceral, preperitoneal, and(More)
BACKGROUND Although liver biopsy is an easy procedure for hospitalized patients and outpatients, some complications may occur. OBJECTIVES To evaluate the efficiency, complications, safety and clinicopathological utility of ultrasonographic-guided percutaneous liver biopsy in diffuse liver disease. PATIENTS AND METHODS In our retrospective study, we(More)
OBJECTIVES To compare the effects of the two most commonly used surgical methods in the management of varicocele disease, namely, microsurgery and high-ligation varicocelectomy, on testicular blood flow changes and mean residual index values in a prospective randomized study. METHODS A total of 56 patients clinically diagnosed with varicocele were(More)
RATIONALE AND OBJECTIVES The goal of this study is to emphasize the value of lesion-focused approach in ultrasonography (US)-guided solid liver lesion biopsies performed under our guidance. MATERIALS AND METHODS In our retrospective study, after the standard preparation for US-guidance solid liver lesion biopsy was accomplished, we performed standard(More)
AIM Pediatric renal biopsy may result in serious hemorrhagic complications, requiring additional diagnostic procedures, blood transfusion, vascular interventions, and prolongation of hospitalization. The aim of the present study was to propose the angled tangential approach technique for real-time ultrasound-guided pediatric percutaneous renal biopsy. (More)
OBJECTIVE To evaluate the accuracy of dynamic laryngeal computed tomography (DLCT) for the detection of vocal cord mobility in larynx cancer. METHODS Vocal cord mobility of 44 patients (36 men; age range, 49-81 years) with larynx cancer was examined; 13 patients were excluded (owing to poor image quality or bilateral vocal cord involvement), and vocal(More)
AIM The aim of the present study was to compare the success and complication rates of pediatric renal biopsy procedures between the angled tangential approach and the traditional approach. METHODS From 2004 to 2009 we prospectively enrolled pediatric patients who had undergone real time ultrasound guided renal biopsy with angled tangential approach. For(More)
BACKGROUND/AIMS Currently, the diagnostic sensitivity of malignant liver mass biopsies is an important problem in the definitive diagnosis. In this study, we aimed to investigate the role of selective peripheral approach to lesion biopsies for diagnostic sensitivity of liver masses. MATERIALS AND METHODS Between June 2007 and March 2011, totally 88(More)
Intracranial metastases represent 7-17% of all brain tumors. Renal cell carcinoma, thyroid cancer, choriocarcinoma, melanoma, retinoblastoma, lung cancer and breast cancer have a propensity for producing hemorrhagic brain metastases. Leukemias have also been rarely reported to cause hemorrhagic brain metastases. We describe an 18-year-old girl diagnosed as(More)
AIM To compare the findings obtained by computerised tomography (CT) enterography, which uses oral neutral contrast material and non-contrasted diffusion-weighted magnetic resonance imaging (DW-MRI) technique and reveal the diagnostic value of DW-MRI in patients with inflammatory bowel diseases. METHODS Patients with established or clinically suspect(More)
