Bowel obstruction incidence in urinary diversion patients: A meta-analysis study

Area of Science:

• Urology
• Surgical Complications
• Gastroenterology

Background:

• Bowel obstruction is a frequent complication following urinary diversion, with reported incidence rates ranging from 0.7% to 11%.
• Existing literature on the prevention and management of postoperative paralytic ileus and urinary postdiversion bowel obstruction remains limited.
• Differences in pathogenesis, management, and outcomes among urinary diversion techniques necessitate further investigation.

Purpose of the Study:

• To systematically review and compare the incidence of bowel obstruction between two common urinary diversion techniques: ileal conduit and continent diversion (specifically orthotopic neobladder).

Main Methods:

• A systematic review was conducted using online databases including PubMed, EBSCOhost, and ProQuest.
• Inclusion criteria comprised full-text articles in English published within the last 10 years.
• Quantitative analysis was performed using RevMan software for meta-analysis.

Main Results:

• Out of 3403 initially identified studies, 12 were included in the final analysis.
• Intestinal obstruction was identified as a significant complication, with one study reporting an incidence of 50.73 per 1000 population.
• The meta-analysis revealed an odds ratio of 0.64 (0.45-0.91) for intestinal obstruction.

Conclusions:

• The study concluded that there is no statistically significant difference in the incidence of intestinal obstruction between the ileal conduit and orthotopic neobladder urinary diversion methods.
