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

Background: Bowel obstruction is a common complication that occurs in patient who underwent urinary diversion with an incidence of 0.7%-11%. Although previous studies have published risk factors, prevention and management of postoperative paralytic ileus, and data on urinary postdiversion bowel obstruction in the literature are still scarce and thus require further investigation of the diversion technique which allegedly has differences in pathogenesis, management, and results. To that end, this study conducted a systematic review study to compare two different diversion techniques, namely ileal conduit and continent diversion, especially orthotopic neobladder. Methods: This study is a systematic review by searching study in online databases such as PubMed, EBSCOhost, and ProQuest. Inclusion criteria included are full-text articles, English language, and articles of the past 10 years. After searching, we analyzed quantitatively using the RevMan application for meta-analysis. Results: From 3403 studies, we got 12 studies that were included in the analysis. In a study conducted from the study of van Hemelrijck et al. stated that intestinal obstruction has an incidence of 50.73-1000, the third-highest when compared with advanced complications such as death (145.07/1000 population) and urinary tract infections (127.03/1000 population). It was found that odds ratio was 0.64 (0.45-0.91). Conclusion: The ileal conduit and orthotopic neobladder methods have no significant difference in the incidence of intestinal obstruction.
