WiScope® single use digital flexible ureteroscope versus reusable flexible ureteroscope for management of renal stones: a prospective randomized study

Objectives To compare the clinical performance and surgical outcomes of the new digital single use flexible ureteroscope (WiScope ® ) with a reusable digital flexible ureteroscope. Patient and methods Our prospective study includes patients with renal stones less than 2 cm who underwent retrograde flexible ureteroscopy and laser lithotripsy. Patients were randomized into two groups: group A included patients who underwent laser lithotripsy using WiScope ® Single use digital flexible ureteroscope and group B included patients who underwent laser lithotripsy using reusable flexible ureteroscope. Image quality, deflection, ease of insertion, maneuverability, and overall performance were assessed using either a visual analog or Likert scale. Operative outcomes and complications were collected and analyzed in both groups. Results A total of 242 patients were included in our study. There were 121 patients in the WiScope ® group and 121 patients in reusable ureteroscope group. The WiScope ® had higher maneuverability (9.3 ± 0.7 vs. 7.2 ± 0.8, P
