We present a longitudinal study of cerebral metabolism using [18F]fluorodeoxyglucose (FDG) positron emission tomography (PET) in a rat model of shockwave-induced traumatic brain injury (SW-TBI). Anesthetized rats received 5 or 10 shockwave pulses to the right anterior lateral or dorsal frontal regions using shockwave lithotripsy. Animals were scanned for FDG uptake at baseline, 3 hours post-injury, and 3 days post-injury, using a small animal PET/CT scanner. FDG uptake at all time points was quantified as the ratio of brain activity relative to peripheral activity in the left ventricle (LV) in the heart (Abrain/ALV) for the entire brain, each hemisphere, and four cortices (motor, cingulate, somatosensory, and restrosplenial)...

OBJECTIVE: Extracorporeal shock wave lithotripsy (ESWL) is a safe and effective treatment for urinary tract calculi. While serious side effects are rare, transient cardiac arrhythmias may occur. New electrocardiographic (ECG) parameters, such as P wave dispersion (PWD), QT dispersion (QTd), T peak to T end (Tp-e) interval, Tp-e interval/QT ratio, and Tp-e interval/corrected QT ratio have been defined to help predict atrial and ventricular arrhythmias. However, effect of ESWL on these ECG parameters has not been previously investigated...

Background: Extracorporeal shockwave lithotripsy (SWL) is a procedure commonly performed to treat nephrolithiasis, with promising results in pediatric patients. However, increasing renal calculi size is directly related to worsening stone-free rates. There are few reports in the literature of >2-cm staghorn calculi that expound on the exact mechanism of treatment in the pediatric population. Case Presentation: We present a case report of a 3-year-old boy who presented with a large 3-cm staghorn calculi effectively treated with one session of SWL followed by a planned staged ureteroscopy for definitive treatment...

OBJECTIVES: Shock wave lithotripsy (SWL) remains the only effective truly non-invasive treatment for nephrolithiasis. While single-treatment success rates may not equal those of ureteroscopy and percutaneous nephrolithotomy, it has an important role to play in the management of stones. In this paper, we outline the latest evidence-based recommendations for maximizing SWL outcomes, while minimizing complications. MATERIALS AND METHODS: A comprehensive review of the current literature was performed regarding maximizing SWL outcomes...

The incidence of pediatric nephrolithiasis is on the rise. The composition of kidney stones in children is different than in adults, as most stones in children have a composition of calcium oxalate and calcium phosphate mixed with a small amount of uric acid. The symptoms of pediatric nephrolithiasis are nonspecific. Computed tomography (CT) is the gold standard for diagnosis; however, because of radiation exposure associated with a CT scan, ultrasonography is also an accepted modality for the diagnosis. Extensive metabolic evaluation is important to rule out an underlying metabolic disorder...
