Clinical application of the F21 multipurpose cystoscope with continuous irrigation capability

Objective To evaluate the safety and clinical performance of an F21 multipurpose cystoscope equipped with a continuous irrigation system in routine urologic procedures. Methods This single-center retrospective study consecutively enrolled 150 patients undergoing F21 multipurpose cystoscope–assisted procedures (50 double-J stent removals, 50 retrograde 5-Fr ureteral catheterizations, and 50 BPH patients receiving PVP).BPH patients had bladder outlet obstruction (Qmax 80 mL.Outcomes included procedure-related complications; IPSS and Qmax were assessed preoperatively and at 3 and 6 months in the PVP cohort. Results All double-J stent removals and retrograde catheterizations were completed successfully under local anesthesia with a consistently clear operative field, and no postoperative complications were observed. All 50 PVP procedures were completed successfully; mean operative time was 65.1 ± 16.9 min, blood loss was
