Postoperative Urinary Retention After Hernia Repair: A Randomized Controlled Trial Identifying Patients at Risk and Assessing the Incidence After Tamsulosin Pretreatment

Seven days of preoperative tamsulosin did not show a statistically significant reduction in postoperative urinary retention in men undergoing elective hernia operations. However, the subgroup analysis did reveal a statistically significant difference in the preoperative IPSS of patients who had postoperative urinary retention and those who did not, possibly indicating that the IPSS could be used as a predictive tool in the future.
