Outcome Measures
Primary Outcomes (1)
Number of Patients to Develop Postoperative Urinary Retention (POUR)
Patients who have not developed POUR will have two consecutive, spontaneous urine voids with residual volume of less than 200 mL, as determined by bladder scan or straight catheterization. Patients who do not successfully have the two spontaneous urine voids of less than 200 mL will be considered as having developed POUR. The incidence of POUR will be compared statistically between those taking and not taking tamsulosin at the time of surgery.
Postop day 1
Secondary Outcomes (5)
Length of Hospital Stay
1-4 days postoperative
Incidence of Discharge to a Skilled Nursing Facility
1-4 days postoperative
Incidence of Surgical Site Infection
Up to two weeks postoperative
Acute Postoperative Pain Medication Dosages
Postoperative day 1 to day of discharge (1-4 days on average)
Incidence of Postoperative Complications
Up to 31 days postoperative
Study Arms (2)
tamsulosin
EXPERIMENTAL0.4 mg daily for five days pre-op through post-op day one (seven total)
