Abstract
Abstract The surgical treatment of stress urinary incontinence is disclosed. The disclosed methods include: 1) a technique of probe passage to avoid injuring the bladder and to provide a more accurate and reproducible capture of the pubocervical fascia lateral to the bladder neck and urethra, 2) anchor fixation of the suspending sutures to the pubic bone to decrease the risk of suture pull through from above and to decrease post-operative pain and 3) a simple and reproducible technique to set a limited tension of the suspending sutures. A description of these methods and results of procedures with some of these methods are disclosed. Novel drill guides, suture passers, suture tensioners, and various related tools and devices for use in the surgical method are also disclosed.
