Post-operative urinary retention (POUR) is one of the most common post-operative complications encountered by most surgical specialties. The incidence of POUR can vary from five to 70%.~Post-operative urinary retention is a prevalent complication. Patients who undergo thoracic surgery have greater urinary retention rates compared to others. Data on effective methods to reduce the risk of POUR in this high-risk group are limited.~All subjects who meet inclusion and exclusion criteria will be invited to participate. There will be no randomization. All will receive tamsulosin in the pre operative period.
Post-Operative Urinary Retention (POUR) in Thoracic Surgery is a prospective interventional study aiming to test the hypothesis that the prophylactic use of tamsulosin prior to thoracic surgery in high risk patients leads to reduce the rates of POUR.
