Mechanism of Action of the Transobturator Sling for Post-Radical Prostatectomy Incontinence: A Multi-institutional Prospective Study Using Dynamic Magnetic Resonance Imaging

We identified that one possible mechanism in improvement in stress urinary incontinence post-TOS placement is the lengthening of the vesicourethral anastomosis to bulbar-urethra distance. This is the first such study utilizing dynamics MRI in post prostatectomy controls, incontinent pre-TOS, and post-TOS to assess and show these findings.
