Summary
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.
- 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.
