  • a clinical evaluation of the new digital single use flexible ureteroscope uscopepu3022 an international prospective multicentered study
    Central European Journal of Urology 1\ 2010, 2018

    Abstract:

    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.

  • first clinical evaluation of a new single use flexible cystoscope dedicated to double j stent removal isiris a european prospective multicenter study
    World Journal of Urology, 2017
    Co-Authors: Steeve Doizi, Guido M. Kamphuis, Jl Palmero, Guido Giusti, Jake Patterson, Silvia Proietti, M Straub, Jean J M C H De La Rosette, Olivier Traxer
    Abstract:

    We evaluated a new single-use digital flexible cystoscope with an integrated grasper designed for double-J stent removal, Isiris™, addressing success rate, image quality, deflection, Maneuverability and grasper functionality. In September 2015, a prospective cohort study was conducted in six tertiary European reference centers. All consecutive patients included underwent double-J stent removal and were 18 years or older. Success rate was defined by complete stent removal. Image quality, deflection, Maneuverability and grasper functionality were rated with a Likert scale. A total of 83 procedures were performed. 82% of procedures were performed in the endoscopy room, while the others were in the operating room since a consecutive endourological intervention was planned. The median duration of stent implantation was 28 days [14; 60]. In five patients, stent removal was not possible. Four patients had an incrusted double-J stent, and in one patient, the stent migrated into the ureter. After unsuccessful attempts of stent removal with conventional flexible cystoscope and grasper, the five patients had to be scheduled for an ureterorenoscopy procedure to remove the stent. In the other 78 patients, all double-J stents were removed successfully. Image quality, deflection, Maneuverability and grasper functionality were rated as “very good” in 72.3, 78.3, 72.3 and 73.5%, respectively. This multicenter clinical evaluation of Isiris™ displayed good image quality, active deflection, Maneuverability and grasper functionality. Further evaluation of stent removal outcomes, cost analysis and microbiology will help to delineate the possible place of Isiris™ in the current practice.
