Purpose: To compare the success and complication rates of ultrasound with fluoroscopically guided Percutaneous Nephrolithotomy (PCNL) in hydronephrotic kidneys. Patients and Methods: The computer archived files of patients with renal calculi who underwent PCNL between October 2007 and November 2012 were retrospectively reviewed. The study included adult patients with hydronephrotic kidneys. Bas...

BACKGROUND The purpose of this study was to evaluate the feasibility of ultrasound-guided core needle biopsy (CNB) performed by a surgeon for mass lesions in the thyroid and lymph nodes. METHODS A single surgeon performed 30 office-based ultrasound-guided CNB procedures for mass lesions in the thyroid and lymph nodes that were previously biopsied by ultrasound-guided fine-needle aspiration cy...

BACKGROUND Ultrasound induces mechanical vibration and heat, causing differentiation and proliferation in osteoblasts. All known in vitro evaluations of ultrasound are, however, performed with longitudinal ultrasound waves. We addressed a question: Do other forms of ultrasound waves, such as guided waves (longitudinal and guided flexural) transduced at a remote location, enhance differentiation...

BACKGROUND Although percutaneous renal biopsy remains an essential tool in the diagnosis and treatment of renal diseases, in recent times the traditional procedure of nephrologists has been performed by non-nephrologists rather than nephrologists at many institutions. The present study assessed the safety and adequacy of tissue yield during percutaneous renal biopsy according to practitioners a...

Ultrasound guided intervention has become the preferred method to diagnose primary neoplasms and suspected metastatic disease. With developments in technology and changes in practice patterns, the types of referrals for ultrasound guided intervention will evolve. The purpose of this review is to highlight a variety of new or relatively new aspects of image guided biopsy and to focus on areas of...

Conventional hydrostatic barium reduction or pneumatic reduction of intussusception is associated with considerable ionizing radiation. The aim of this study was to evaluate ultrasound-guided hydrostatic reduction for childhood intussusception using water enema. A total of 76 children who diagnosed as having intussusception were referred to Doctor Sheikh Children Hospital in Mashhad (northeast ...

BACKGROUND Image-guided procedures such as computed tomography (CT) guided, neuronavigator-guided and ultrasound-guided methods can assist neurosurgeons in localizing the intraparenchymal lesion of the brain. However, despite improvements in the imaging techniques, an accurate diagnosis of intrinsic lesion requires tissue sampling and histological verification. AIMS The present study was carr...

OBJECTIVE To investigate whether the visualization modality (ultrasound or fluoroscopy) used during shockwave lithotripsy (SWL) affects the clinical outcome in those instances where both imaging modalities are optional. METHODS Between November 2014 and July 2016, 114 patients with radiopaque upper urinary tract calculi were randomly assigned to an ultrasound- or fluoroscopy-guided SWL group ...
