Bladder Neck Incision (M6620)

  • Length of surgery:

    1 hrs

  • Anaesthetic:

    General Anaesthetic

  • Hospital stay :

    1 night (In-patient)

  • Time off work :

    1-3 days

  • Time off exercise:

    3 weeks

  • Time to fully settle :
    3 months
  • Post-op care:

    A urethral catheter is typically left in place for 3 days following the procedure and then removed.

    You may experience mild stinging or a feeling of increased urgency during urination for 24–48 hours after catheter removal. A small amount of blood in the urine is common and should settle within a couple of days. Drinking plenty of fluids helps flush the bladder and reduce discomfort.

    In rare cases, difficulty emptying the bladder may occur, and temporary self-catheterisation may be necessary. If you experience fever, persistent pain, or are unable to pass urine, please contact the clinic promptly. A follow-up plan will be discussed as part of your care.

    Important Notes Based on Procedure Indication:

    • Post-Radical Prostatectomy Patients (BNI of scarred anastomosis):
      Urinary incontinence may become apparent after the stricture is released. This is due to unmasking of underlying sphincter weakness, which had previously been concealed by the obstruction. Further assessment and treatment for incontinence may be required.

    • Post-TURP/HOLEP Patients (BNI of contracted bladder neck):
      Incontinence is not expected if the external urethral sphincter is intact. However, a follow-up cystoscopy at 3 months is performed, as recurrence of bladder neck contracture is relatively common and may require further management.

Bladder Neck Incision (BNI) is an endoscopic procedure performed to relieve obstruction at the bladder outlet. This is typically caused by a bladder neck contracture following TURP or HoLEP, or by an anastomotic stricture after prostatectomy for prostate cancer. The incision is made either at the bladder neck or—when treating a post-prostatectomy anastomotic stricture—at the level of the external urethral sphincter, which is often involved in the scarring.

A urethral catheter is left in place for 3 days following the procedure. A follow-up cystoscopy is usually arranged at 3 months to assess for recurrence, particularly in cases of bladder neck contracture, which has a high rate of re-narrowing.

In men previously treated for prostate cancer, urinary incontinence may become apparent if the BNI unmasks underlying sphincter weakness that was previously compensated by the stricture.
