What this trial studies

This feasibility study investigates whether Tamsulosin can reduce the incidence of postoperative urinary retention (POUR) in older men undergoing thoracic oncological surgery. The study focuses on men aged 55 and older who are scheduled for surgery and will take Tamsulosin for seven days prior to the procedure. Researchers will measure spontaneous voids and assess residual urine post-surgery to evaluate the effectiveness of the treatment. The goal is to determine if Tamsulosin can improve urinary function and reduce complications associated with POUR.

Who should consider this trial

Good fit: Ideal candidates are males aged 55 and older scheduled for thoracic oncological surgery.

Not a fit: Patients currently using Tamsulosin or those with certain medical conditions such as hypotension or heart failure may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of urinary retention and related complications in older men after thoracic surgery.

How similar studies have performed: Previous studies have indicated that Tamsulosin may effectively reduce urinary retention, suggesting potential success for this approach.
