Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Retained Urinary Catheter<br> | Procedure: Total knee arthroplasty<br>* A surgical procedure in which parts of the knee joint are replaced with artificial parts (prostheses)<br>Procedure: Urinary Catheterization<br>* Urinary catheterization is a latex, polyurethane, or silicone tube known as a urinary catheter is inserted into a patient's bladder via the urethra. Catheterization allows the patient's urine to drain freely from the bladder for collection.<br>|
| Experimental: Non-retained Urinary Catheter<br> | Procedure: Total knee arthroplasty<br>* A surgical procedure in which parts of the knee joint are replaced with artificial parts (prostheses)<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| postoperative urinary retention | Patients who didn't void within 6 hours with suprapubic discomfort and had a urinary volume 400 mL or more confirmed by single intermittent catheterization | 6 hours after surgery and 6 hours after remove urinary catherter | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| urinary tract infection | An infection of the kidney, ureter, bladder, or urethra. The symptoms are burning with urination and having to urinate frequently and fever > 38° C. Urine culture shows a bacterial colony count of greater than or equal to ten to the fifth colony-forming units per mL of a typical urinary tract organism. | 7 days after surgery |
