The aim of this clinical study is to optimize treatment outcomes in patients with mixed forms of urinary incontinence by implanting an adjustable suburethral sling and to determine factors influencing treatment effectiveness. The main questions it aims to answer are:

1. What is the effectiveness of an adjustable suburethral sling in patients with mixed urinary incontinence?
2. How do preoperative medications and other factors affect the effectiveness of adjustable suburethral sling implantation?
3. How does quality of life change in these patients after surgery? Participants will undergo implantation of an adjustable suburethral sling. Postoperatively, the effectiveness of the sling for mixed urinary incontinence will be assessed. Predictors of treatment effectiveness will also be identified.

Patients will be examined 24 hours after surgery, 2 months later, and 1 year later.
