Introduction: We assessed the clinical performance of a new digital single-use flexible ureteroscope (UscopePU3022).

Material And Methods: A prospective cohort study was carried out across 11 centers (July-Oct. 2017). The UscopePU3022 was assessed regarding ease of insertion; deflection, image quality, maneuverability and overall performance using either a visual analog* or Likert scale.

Results: A total of 56 procedures were performed in 11 centers (16 surgeons) with the indication being renal stones in 83%. The median score for ease of scope insertion was 10 (3-10). Intraoperative maneuverability was rated as 'good' in 38% and 'very good' in 52%. Visual quality was rated as 'poor or bad' in 18%, 'fair' in 37% and 'good or very good' in 43%. Two scopes failed intraoperatively (4%). Preoperative and postoperative median upward and downward deflection was 270 degrees. Compared to standard flexible ureteroscopy (f-URS) maneuverability was rated as 'equivalent' in 30% and 'better' in 60%; visual quality was 'worse' in 38% and 'equivalent or better' in 62%; limb fatigue scores were 'better' in 86%; and overall performance was 'worse' in 55% and 'equivalent or better' in 45%.

Conclusions: UscopeTM3022 performed well with regards to maneuverability, deflection and limb fatigue and appears to be at least non-inferior to standard f-URS with regards to these parameters. Poor image quality is a concern for UscopePU3022 with it receiving a low overall performance rating when compared to standard f-URS. Despite this it scored highly when investigators were asked if they would use it in their practice if it was cost-effective to do so.

Background: Flexible ureteroscopy (FURS) is increasingly used as the first-line treatment for urological procedures. Disposable digital (dd-)FURS has been developed to overcome limitations such as durability, degradation, and repair cost of reusable scopes. The diameter of commercially-available models ranges from 7.

Consumers have several options when confronted with less environmentally friendly packaging like water in single use plastic bottles - they can ignore environmental concerns and proceed with a purchase, refuse to buy any such product, seek out a less damaging version like water in biodegradable bottles, and/or engage in offsetting/compensatory behavior such as donating to a charity. Understanding how consumers value these options is an important academic and management challenge. To address this, a stated choice experiment is employed.

Electronic address:

This study introduces an advanced bioanalytical platform that combines digital microfluidics (DMF) with Raman spectroscopy, effectively addressing common issues in bioanalysis such as sample contamination, excessive consumption of samples and reagents, and manual handling. Our innovative system is engineered to handle diverse sample types and enables both sample preparation and in-situ analysis on a single device, utilizing less than 5 μL of samples and reagents. It incorporates a Translucent Raman Enhancement Stack (TRES) sensor, which boosts the detection signal, and includes droplet-driving functionality for automated processing of complex samples in a compact setting.
