Urethral stones can become impacted in the posterior urethra, typically presenting with varying degrees of acute urinary retention and lower urinary tract symptoms. These are traditionally treated in the inpatient setting, with external urethrotomy or endoscopic push-back of the calculus into the urinary bladder followed by cystolitholapaxy or cystolithotripsy. However, these methods are invasive, involve general anesthesia, and require radiation. In this report, we describe a simple, minimally invasive, and safe alternative technique to visualize and remove impacted prostatic urethral stones under the real-time guidance of transrectal ultrasonography (TRUS)...

BACKGROUND AND AIM: Complete gastrointestinal strictures are a technically demanding problem. In this setting, an anterograde technique is associated with a high risk of complications and a combined anterograde-retrograde technique requires a prior ostomy. Our aim was to assess the outcome of a first case series for the management of complete gastrointestinal strictures using endoscopic ultrasound (EUS)-guided puncture as a novel endoscopic approach. PATIENTS AND METHODS: This retrospective case-series describes four cases that were referred for treatment of complete benign gastrointestinal strictures, three upper and one lower...

PURPOSE: Radiofrequency ablation for liver tumors (liver RFA) is widely performed under ultrasound guidance. However, discriminating between the tumor and the needle is often difficult because of cavitation caused by RFA-induced coagulation. An unclear ultrasound image can lead to complications and tumor residue. Therefore, image-guided navigation systems based on fiducial registration have been developed. Fiducial points are usually set on a patient's skin. But the use of internal fiducial points can improve the accuracy of navigation...

Optical coherence tomography (OCT) is an intra-coronary diagnostic technique that provides detailed imagings of blood vessels in the current cardiac catheterization laboratory. The higher resolution of OCT often provides superior delineation of each structure compared with intravascular ultrasound (IVUS), and it can reliably visualize the microstructure of normal and diseased arteries. The capabilities of OCT are well suited for the identification of calcified plaque and neointima formation after stent implantation...

Despite the increasing number of clinical trials in gene therapy, no ideal methods still allow non-viral gene transfer in deep tissues such as the liver. We were interested in ultrasound (US)-mediated gene delivery to provide long term liver expression. For this purpose, new positively charged microbubbles were designed and complexed with pFAR4, a highly efficient small length miniplasmid DNA devoid of antibiotic resistance sequence. Sonoporation parameters, such as insonation time, acoustic pressure and duration of plasmid injection were controlled under ultrasound imaging guidance...

In pigs, the deep location of the common carotid artery and overlying sternomastoideus muscle in the neck has led to the recommendation for a surgical cutdown for common carotid access, as opposed to minimally invasive techniques for vascular access. We sought to determine if direct percutaneous common carotid artery access in piglets is attainable. Seventeen piglets were anesthetized and intubated. Under two-dimensional and color flow Doppler ultrasound guidance, a 21 gauge needle was utilized to access the right common carotid artery...

Radiation therapy has emerged as a useful alternative therapy for patients with early-stage, non-resectable lung cancer. In patients whose malignancies are difficult to localize on computed tomography imaging, such therapy becomes difficult. Fiducial markers are frequently placed in peripheral pulmonary lesions to assist radiation therapy. Although placement of markers under linear endobronchial ultrasonography within mediastinal and hilar lymph nodes has been reported, no strategy has been described to assist radiotherapy of purely endobronchial tumors...
