title: Risk Factors for Postoperative Retention After Hemorrhoidectomy: A Cohort Study.
abstract: The objective of this study was to identify the risk factors for urinary retention after hemorrhoidectomy. With the approval of West China Hospital of Sichuan University Ethics Board, data were abstracted from 961 charts of patients who underwent hemorrhoidectomy from January 1, 2009, to June 30, 2011. The outcome was urinary retention in the first 24 hours after surgery. Risk factors were identified using multivariable logistic regression, and they were expressed as odds ratios or 95% confidence intervals. The overall urinary retention rate was 14.8% (n = 142). Significant risk factors associated with postoperative urinary retention included female gender, anesthesia methods, severity of hemorrhoid, a large amount of intravenous fluid administered perioperatively, and length of hospital stay. Logistic regression analysis revealed that female gender (odds ratio, 2.607; p < .01), sacral anesthesia (odds ratio, 2.481; p = .02), more than 3 hemorrhoids resected (odds ratio, 2.658; p < .01), hemorrhoids having 4 degrees of severity (odds ratio, 3.101; p < .01), intravenous fluids > 700 ml (odds ratio, 1.597; p = .02), and length of stay more than 7 days (odds ratio, 1.852; p < .01) were significant predictors of urinary retention post-hemorrhoidectomy.
