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 <10 mL/s), and major exclusions included prostate cancer and prostate volume >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 <60 mL, postoperative irrigation averaged 17 h, and catheter removal occurred on postoperative days 3–5. In the PVP group, Qmax increased from 6.314 preoperatively to 21.716 at 3 months and 21.006 at 6 months, while IPSS decreased from 23.540 to 4.700 and 4.420, respectively (all p<0.001). At the 3-month and 6-month postoperative follow-up time points, none of the patients developed complications such as urinary incontinence, urethral stricture, bladder neck contracture, or voiding dysfunction. Conclusion The F21 multipurpose cystoscope with continuous irrigation provides stable visualization and supports both routine cystoscopic interventions and PVP in a small-caliber platform, demonstrating favorable safety and functional outcomes.
