Analysis of risk factors for acute urinary retention after non-urogenital surgery

초록

Purpose: We performed this study to analyze the risk factors that are related to acute urinary retention in patients undergoing non-urogenital surgery. Materials and Methods: We retrospectively analyzed the records of 127 patients who were referred to the urology department because of acute urinary retention after non-urogenital surgery at our institution between January 2004 and December 2005, and we also recuited 258 consecutive patients who were undergoing non-urogenital surgery at our institution during the same period as a control group. Multiple parameters were divided into patient factors, surgical factors and anesthetic factors, and these factors were analyzed using univariate and multivariate regression analyses between the non-retention and the retention groups. Results: On the multivariate analysis, age (≥50 years, p=0.037; odds ratio (OR)=2.8), gender (women, p=0.028; OR=2.5), comorbidity with diabetes mellitus (p=0.003; OR=5.8) were found to independently increase the risk of acute urinary retention. After re-adjustment for the patients' gender, age, body mass index, diabetes, hypertension, the inability to self-ambulate after the removal of a Foley catheter (p=0.001; adjusted odds ratio (AOR)= 3.8), the amount of intraoperative fluids (≥4,000ml, p=0.017; AOR=4.8) were found to independently increase the risk of acute urinary retention. Conclusions: The possibility of acute urinary retention for patients undergoing non-urogenital surgery and who have these risk factors is high; therefore, carefully managing urination for the prevention of postoperative acute urinary retention is needed. It is also necessary to make doctors in other departments recognize the importance of this issue.
