March 21, 2019 updated by: Andrew Urquhart, University of Michigan

Prospective, Randomized, Double-Blind, Placebo-Controlled Trial of Prophylactic Tamsulosin for Postoperative Urinary Retention in Primary Total Hip and Knee Arthroplasty Patients

The study aims to evaluate the efficacy of prophylactic tamsulosin in reducing the incidence of postoperative urinary retention in primary total knee and hip arthroplasty patients.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Prophylactic administration of tamsulosin will be compared to a placebo to evaluate the effectiveness in reducing the incidence of postoperative urinary retention in total hip and knee arthroplasty patients.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

35 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Patients to Develop Postoperative Urinary Retention (POUR)
Time Frame: Postop day 1
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 Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Length of Hospital Stay
Time Frame: 1-4 days postoperative
Length of hospital stay will be recorded in days and compared statistically between the two groups .
1-4 days postoperative
Incidence of Discharge to a Skilled Nursing Facility
Time Frame: 1-4 days postoperative
Discharge to a skilled nursing facility will be recorded (yes/no) and compared statistically between the two groups.
1-4 days postoperative
Incidence of Surgical Site Infection
Time Frame: Up to two weeks postoperative
Surgical site infection will be recorded (yes/no) and compared statistically between the two groups.
Up to two weeks postoperative
Acute Postoperative Pain Medication Dosages
Time Frame: Postoperative day 1 to day of discharge (1-4 days on average)

Postoperative day 1 to day of discharge (1-4 days on average)
Incidence of Postoperative Complications
Time Frame: Up to 31 days postoperative
Postoperative complications will be recorded and the incidence will be compared statistically between the two groups.
