Prostate cancer is the most common cancer in elderly men, and radical prostatectomy is a widely used treatment for clinically localized prostate cancer. While many men experience temporary urinary function issues after surgery, most recover over one to two years. However, a significant number of patients face persistent urinary incontinence, severely impacting their quality of life. This ongoing condition leads to a range of challenges, including physical, emotional, social, and occupational difficulties, as well as significant hygiene concerns. Furthermore, urinary incontinence imposes substantial costs on both patients and healthcare systems.
