Transurethral Incision of the Bladder Neck (TUIBN) Guideline Summary

Introduction to TUIBN

• TUIBN is an outpatient endoscopic surgical procedure primarily used for smaller prostates (≤30 grams) and bladder neck contractures, involving making one or two incisions in the prostate and prostate capsule with a specialized knife, which reduces constriction of the urethra 1

Comparison of TUIBN to Other Procedures

• TUIBN provides equivalent symptomatic improvement to TURP in appropriately selected patients 1
• TUIBN has significantly reduced risk of retrograde ejaculation compared to TURP 1
• TUIBN has shorter operative time and less bleeding than TURP 1, 2
• TUIBN has higher reoperation rates (18.4%) compared to TURP (7.2%) 2

Factors Influencing Long-term Success of TUIBN

• Smaller prostate size (≤30 grams) is a factor that can influence the long-term success of TUIBN 1

Recurrence and Complications

• Higher recurrence rates (18.4%) compared to TURP (7.2%) over longer periods 2
