From molecular to macro: the key role of the apical ligaments in uterovaginal support.

To explain the pathophysiology of pelvic organ prolapse, we must first understand the complexities of the normal support structures of the uterus and vagina. In this review, we focus on the apical ligaments, which include the cardinal and uterosacral ligaments. The aims of this review are the following: (1) to provide an overview of the anatomy and histology of the ligaments; (2) to summarize the imaging and biomechanical studies of the ligament properties and the way they relate to anterior and posterior vaginal wall prolapse; and (3) to synthesize these findings into a conceptual model for the progression of prolapse.

The Latzko: A high-value, versatile vesicovaginal fistula repair.

The Latzko transvaginal vesicovaginal fistula repair is a highly effective treatment for even complex fistulae. Our video demonstrates the Latzko repair technique and its application in a variety of circumstances that include fistula management concurrent with treatment of uterovaginal prolapse, after complex urologic surgery, and in the postpartum setting after urologic injury. The technique of the procedure varies only slightly in these diverse conditions. The basic steps begin with hydro-dissecting the epithelium from the underlying fascia surrounding the fistula tract, followed by denuding the epithelium within a circumscribing incision around the fistula. The fistula is then closed with a purse-string suture placed just outside the epithelialized tract. Next, several layers of imbricating sutures are placed to close the defect. Finally, the vaginal epithelium is closed.
