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...

STUDY OBJECTIVE To apply ergonomic task analysis to the performance of ultrasound-guided (US-guided) femoral nerve block (FNB) in an acute hospital setting. DESIGN Pilot prospective observational study. SETTING Orthopedic operating room of a regional trauma hospital. SUBJECTS 15 anesthesiologists of various levels of experience in US-guided FNB (estimated minimum experience < 10 procedure...

BACKGROUND Ultrasound (US) is more sensitive than physical examination alone in determining axillary lymph node involvement during preliminary staging of breast carcinoma. Due to occasional overlap of sonographic features of benign and indeterminate lymph nodes, fine-needle aspiration (FNA) of sonographically indeterminate/suspicious lymph nodes can provide a more definitive diagnosis than US a...

results of the 53 neck dissection specimens, histopathology showed metastases in 16 cases. the overall accuracy of usgfna, us and palpation was 96%, 68% and 70%, respectively. the specificity of usgfna was superior to palpation and us alone. usgfna had the highest sensitivity, predictive value and accuracy in detecting cervical metastases compared with other performed tests. conclusion in our s...

The aim of this study was to compare the mid-term effects and benefits of ultrasound (US)-guided and fluoroscopy (FL)-guided medial branch blocks (MBBs) for chronic lower lumbar facet joint pain through pain relief, functional improvement, and injection efficiency evaluation.Patients with chronic lumbar facet joint pain who received US (n = 68) or FL-guided MBBs (n = 78) were included in this r...

BACKGROUND AND PURPOSE Injection therapies play a major role in the treatment of lower back pain and are to date performed mainly under CT- or fluoroscopic guidance. We conducted this study to evaluate the accuracy, time savings, radiation doses, and pain relief of US-guided pararadicular injections versus CT-controlled interventions in the lumbar spine in a prospective randomized clinical tria...

AIM The aim of this study was to evaluate our experience with adequate liver biopsy samples and compare the complication rates of blind and US-guided biopsies, as well as to compare the histological yield of blind and US-guided biopsy specimens. METHODS We retrospectively analyzed 205 consecutive patients that underwent liver biopsies during a 12-month period. Liver biopsy was performed via t...

Central vascular access is sometimes required for hemodynamic monitoring and infusion of fluids and medications in the pediatric emergency department. In many cases, it is attempted after failed peripheral venous and intraosseous access. Some evidence exists demonstrating benefits of ultrasound (US)-guided central vascular cannulation in adults in emergency departments. With appropriate educati...
