Brief Summary

Postoperative urinary retention is a frequent complication of spinal surgeries and impacts a large portion of this population which results in increased morbidity as a result of increased number of catheterizations, urinary tract infections (UTIs) and prolonged hospital stays. With the addition of Tamsulosin, the investigators would anticipate a reduction in the incidence and duration of postoperative urinary retention and therefore a reduction in morbidity related to treatment of urinary retention as well as shortened hospital stays.

Outcome Measures

Primary Outcomes (1)

  • Incidence of Postoperative Urinary Retention

    Post operative urinary retention (POUR) will be defined as any of the following: 1\) Estimated post-void residual (PVR) volume of urine greater than or equal to 300 mL; 2) Estimated retention urine volume of greater than or equal to 500 mL in patients unable to void; 3) Patients experiencing discomfort or distension and unable to void with lesser residual urine volume than 500 ml.

    participants will be followed for the duration of the hospital stay, an expected average of 5 days

Secondary Outcomes (1)

  • Duration of Postoperative Urinary Retention

    participants will be followed for the duration of the hospital stay, an expected average of 5 days

Study Arms (2)

Drug: Tamsulosin hydrochloride

Placebo

PLACEBO COMPARATOR

Participants randomized to this arm will receive a daily placebo capsule matching the active study drug from 5 days prior to the operation until hospital discharge.

Other: Placebo

Interventions
