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.
