Congenital hernia of the cord is a different type of ventral abdominal wall defect in which the bowel usually herniates into the base of normally inserted umbilical cord through a patent umbilical ring. It is rare congenital anomaly with incidence of 1 in 5000. Although it was described as a distinct entity since 1920s it is often misdiagnosed as a small omphalocele. We present an unusal case of term male newborn with umbilical cord hernia associated with patent omphalomesenteric duct. The diagnose was made after birth despite antenatal ultrasound scans and it is managed successfully with uneventful recovery...

In daily clinical practice, intrascrotal lesion are commonly detected, both by clinical examination either by ultrasound scan. While 95% of testicular lesions are malignant, most paratesticular lesions are benign. Among these, intrascrotal lipomas must be take into account in differential diagnosis. When they originate from scrotal wall, they named "primary scrotal lipoma". We describe a case of a primary intrascrotal lipoma diagnosed after surgical excision in a young man presented at our Urological Department complaining a painful left scrotal mass...

OBJECTIVE: Urolithiasis of the transplanted kidney has an incidence of 0.2 to 1.7%, it increases the risk of infection in immunosuppressed patients and it can lead to ureteral obstruction that is often associated with deterioration of renal function. Urolithiasis of the transplanted kidney has different characteristics compared to the native kidney, due to the absence of innervation, which does not lead to colic pain. Percutaneous approach is an optimal choice in transplant patients. MATERIAL AND METHODS: Here we report our experience in two cadaveric transplant patients with urolithiasis...

Iron oxide nanoparticles (IONPs) are becoming increasingly used and intensively investigated in the field of medical imaging. They are currently FDA approved for magnetic resonance imaging (MRI), and it would be highly desirable to visualize them by ultrasound as well. Previous reports using the conventional ultrasound B-scan (pulse-echo) imaging technique have shown very limited detectability of these particles. The aim of this study is to explore the feasibility of imaging IONPs using the through-transmission ultrasound methodology and demonstrate their detectability using ultrasonic computed tomography (UCT)...

Magnesium ammonium phosphate (MAP) crystallization could be utilized for the recovery of phosphorus from wastewater. However, the effectiveness of the recovery is largely determined by the crystallization process, which is very hard to be directly observed. As a result, a specific ultrasonic device was designed to investigate the crystallization characteristics of MAP under various ultrasonic conditions. The results demonstrated that the metastable zone width (MZW) narrowed along with the rising of the ultrasonic power...
