The modified Mitrofanoff procedure using a direct appendicovesical anastomosis offers a minimally invasive solution for urinary continence. This technique, applied laparoscopically, resulted in all patients remaining dry with reduced complications.

Area of Science:

  • Urology
  • Surgical Innovation

Background:

  • The Mitrofanoff principle enables continent urinary diversion.
  • Traditional techniques can be complex and carry risks.

Purpose of the Study:

  • To review experience with a modified Mitrofanoff procedure.
  • To evaluate a direct appendicovesical anastomosis technique without a submucosal tunnel.
  • To assess the feasibility of a laparoscopic approach.

Main Methods:

  • Eight patients with urethral stricture or hypotonic bladder underwent the procedure.
  • A modified direct appendicovesical anastomosis was used.
  • A complete laparoscopic approach was employed in four patients.

Main Results:

  • All eight patients achieved complete urinary continence (dryness) after a mean follow-up of 19.5 months.

Related Experiment Videos

  • Three patients had persistent positive urine cultures, but no renal impairment.
  • The modified technique reduced operative time and complication rates.

    • Conclusions:

    • The modified direct appendicovesical anastomosis is effective for achieving urinary continence.
    • The laparoscopic approach offers benefits of minimally invasive surgery.
    • This technique preserves urinary continence with a favorable safety profile.
