Data Collection Post Radical Prostatectomy

Not yet recruiting

• Conditions: BPH; Radical Prostatectomy; Stress Urinary Incontinence

• Registration Number: NCT06351579
• Lead Sponsor: Levee Medical, Inc.

Brief Summary

The study is to collect information on patients undergoing radical prostatectomy (RP), with a primary focus on the occurrence, duration, and severity of post-prostatectomy incontinence. Data will be collected at multiple time points, allowing for a dynamic understanding of urinary incontinence patterns at post RP.

Detailed Description

Urinary incontinence is predominantly iatrogenic following radical prostatectomy (RP). Surgical removal of the prostate leads to a shortened urethra, widened bladder neck, and diminished urethral support. This results in increased demand on the urinary sphincter to maintain urinary continence. Most men will experience acute urinary incontinence following RP. Continence progressively improves over time; however, it is estimated that between 5-15% of men will experience chronic urinary incontinence.

Current treatments for post-prostatectomy urinary incontinence include conservative therapies such as pelvic floor muscle training and surgical treatments.

This study is to systematically collect detailed information on patients undergoing radical prostatectomy, with a primary focus on the occurrence, duration, and severity of post-prostatectomy incontinence. Data will be collected at multiple time points, allowing for a dynamic understanding of urinary incontinence patterns at post RP.

18. Any significant medical history that would pose an unreasonable risk or make the subject unsuitable for the study per investigator discretion
19. Any cognitive or psychiatric condition that interferes with or precludes direct and accurate communication with the study investigator regarding the study or affect the ability to complete the study quality of life questionnaires
20. Subject currently participating in other investigational studies unless approved by the Sponsor in writing

Study & Design

• Study Type: OBSERVATIONAL
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
The change in average 24-hour pad weight over time	Baseline, post-foley, 6 weeks, 3 months, 6 months, and 12 months post-prostatectomy procedure.	The 24-hour (at-home) pad weight test - The pads are pre-weighed prior to providing them to subjects. The test should be started with an empty bladder. The subject will wear pads and perform their normal daily activities for 24 hours. The subject will be asked to change the pads approximately once every 6 hours during waking hours, or more frequently as needed. The pads will be stored in an air tight bag or container after removal, stored in a refrigerator, and brought to the site at the required follow-up visit for weighing.

Secondary Outcome Measures

Name	Time	Method
Change in pad weight during a 1-hour provocative pad weight test	Baseline, post-foley, 6 weeks, 3 months, 6 months, and 12 months post-prostatectomy procedure.	The 1-hour pad test involves the following: * Subject puts on a pre-weighed pad and is asked to avoid voiding; * Subject drinks 500 ml of sodium-free liquid in \<15 minutes, then sits or rests; * Subjects walks for 30 minutes, including climbing one flight of stairs (up and down); * Subject performs the following activities: standing up from sitting (10x), coughing vigorously (10x), running on the spot for 1 minute, bending to pick up an object from the floor (5x), and washing hands in running water for 1 minute; * The total amount of urine leaked is determined by weighing the pad. If voiding is urgent and unavoidable, the test is terminated. Collect voiding volume and repeat the test after re-hydration.
