Summary

Converting from a colonic conduit urinary diversion to a Mainz pouch II (recto-sigmoid pouch) offers long-term continence. This procedure improves quality of life by eliminating external appliances for patients desiring continent urinary diversion.

Area of Science:

  • Urology
  • Pediatric Surgery
  • Reconstructive Urology

Background:

  • Urinary diversion in childhood can necessitate external appliances.
  • Some patients seek conversion to continent urinary diversion for improved quality of life.

Purpose of the Study:

  • To evaluate the long-term outcomes of converting colonic conduit urinary diversions to continent Mainz pouch II (recto-sigmoid pouch) diversions.
  • To assess patient continence and renal function after conversion.

Main Methods:

  • Retrospective review of 139 patients who underwent Mainz pouch II diversion between 1992 and 2003.
  • Four patients had prior colonic conduit diversion converted to Mainz pouch II without ureteric reimplantation.
  • Mean follow-up was 11.5 years post-conversion.

Main Results:

  • No early complications were observed.
  • One patient required nephrectomy 5 years post-conversion due to uretero-intestinal obstruction and pyelonephritis.
  • All patients achieved day and night urinary continence; three required alkali supplementation for acidosis.

Conclusions:

  • The Mainz pouch II is a viable option for converting incontinent urinary diversions to continent ones.
  • Conversion can lead to sustained renal function and excellent continence.
  • This procedure enhances patient quality of life by removing the need for external appliances.
