Area of Science:

  • Urology
  • Surgical Oncology

Context:

  • Bladder cancer necessitates urinary diversion procedures.
  • The Mainz pouch is a type of continent urinary diversion.
  • Umbilical stoma construction presents unique challenges and benefits.

Purpose:

  • To evaluate the efficacy and outcomes of the Mainz pouch urinary diversion utilizing an umbilical stoma.
  • To assess the cosmetic and functional results of umbilical stomas in Mainz pouch procedures.
  • To compare the complication rates of umbilical stomas versus other stoma sites.

Summary:

  • The Mainz pouch urinary diversion was performed in 23 bladder cancer patients; 12 had an umbilical stoma constructed using ileum or appendix.
  • Umbilical stomas yielded satisfactory cosmetic results, good urinary continence, and ease of self-catheterization in most patients.

  • Complications were infrequent, including one case each of catheterization difficulty, stomal stenosis, and acute renal failure; the umbilical stoma demonstrated advantages over other sites.

    • Impact:

    • Umbilical stomas in Mainz pouch urinary diversion offer excellent cosmetic outcomes and functional results.
    • This approach reduces the need for external devices and minimizes complications like parastomal hernia.
    • The study highlights the umbilical stoma as a favorable option for Mainz pouch urinary diversion in select bladder cancer patients.
