Objectives:
The prevalent use of minimally invasive midurethral slings for the treatment of stress urinary incontinence in the last several decades has resulted in fewer Burch procedures being performed and diminished surgical experience in performing the Burch colposuspension. However, recent antimesh media has resulted in more patients requesting nonmesh anti-incontinence procedures and a subsequent need for surgeons to refamiliarize themselves with the Burch procedure and its relevant anatomy. The objective of this study was to evaluate the relationships of Burch sutures to surrounding neurovascular anatomic structures in the human cadaver.
Methods:
The retropubic space of 11 unembalmed female cadavers was dissected, and a Burch procedure performed. The distance from the Burch sutures' location through both Cooper's ligament and the vagina to the obturator neurovascular bundle and external iliac vessels was measured.
Results:
The mean distance from the most lateral stitch in Cooper's ligament to the obturator bundle was 25.9 ± 7.6 mm and to the external iliac vessels was 28.9 ± 9.3 mm, and in some instances, these structures were less than 1.5 cm away.
Conclusions:
The obturator bundle and external iliac lie, on average, within 3 cm of sutures placed during a Burch colposuspension. Knowledge of these anatomical relationships is valuable when dissecting the space of Retzius and placing sutures for a Burch to avoid injury.

01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
