The invention relates to methods for the treatment of urinary incontinence (UI) and stress urinary incontinence (SUI) in both men and women by replacement of a damaged, absent or injured pubo-urethral ligament (PUL) via a simple injection of “Regenerative Glue.” For example, in the case of UI, the injection of “Regenerative Glue” at the PUL site will adhere the ventral surface of the urethra to the dorsal surface of the symphysis pubis (i.e. the space of Retzius), and further provide regenerative material for continuous replacement of deficient tissues and cells. “The Regenerative Glue” can be made from several commercially available materials including biocompatible glues, fibrin sealant or biocompatible gels combined with Meschencymal stem cells (MSC) derived from bone marrow or adipose tissues.
