Bowel-flap tubes for continent cutaneous urinary diversion
Abstract
The appendix stoma for Mainz-pouch continent cutaneous urinary diversion is reliable and easy to perform. Two new continence mechanisms were developed for patients in whom the appendix is not available or usable. A seromuscular tube was used in 27 patients (12 women, 15 men, mean age 63 years) and a bowel-wall tube was used in 24 patients (13 women, 11 men, mean age 57 years) as the continence mechanism for continent cutaneous urinary diversion. At a mean follow-up of 32 months (range 2-68 months), 93% of patients with a seromuscular tube and 92% of those with a bowel-wall tube are continent day and night. Four early and nine late stoma-specific complications have occurred, requiring seven open surgical revisions. Thus far, both techniques have fulfilled all requirements as continence mechanisms for continent cutaneous urinary diversion. However, the reliability, advantages, and disadvantages of these techniques have to be confirmed in further long-term studies.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 27 participants or records.
