Virtual reality for pain control during shock wave lithotripsy: a randomized controlled study.

Purpose: Although external shock wave lithotripsy (SWL) is an outpatient procedure generally not requiring anesthesia or sedation, patients may experience pain during the procedure. The aim of this study is to evaluate whether a virtual reality device is effective in reducing patient-reported pain during the procedure, consequently leading to exposure to higher energy levels and better clinical outcomes.

Methods: Inclusion criteria for SWL were according to the latest EAU guidelines on urolithiasis.

Urethro-venous fistula following straddle injury: A case report and image series.

We present a case of a 49-year-old man with an acute traumatic urethral injury after a fall onto a fence post. Retrograde contrast study showed a contrast leak and suspicion of a traumatic urethro-venous fistula. We successfully placed a urethral indwelling catheter (IDC) in the operating room and follow-up urethrocystoscopy showed healing of the injury.

A Model for Estimating Biological Age From Physiological Biomarkers of Healthy Aging: Cross-sectional Study.

Background: Individual differences in the rate of aging and susceptibility to disease are not accounted for by chronological age alone. These individual differences are better explained by biological age, which may be estimated by biomarker prediction models. In the light of the aging demographics of the global population and the increase in lifestyle-related morbidities, it is interesting to invent a new biological age model to be used for health promotion.

Frequency shift algorithm: Design of a baseband phase locked loop for frequency-domain multiplexing readout of x-ray transition-edge sensor microcalorimeters.

The Transition-Edge Sensor (TES) is an extremely sensitive device, which is used to measure the energy of individual x-ray photons. For astronomical spectrometry applications, SRON develops a frequency domain multiplexing readout system for kilopixel arrays of such TESs. Each TES is voltage biased at a specific frequency in the range of 1-5 MHz.
