  1. Uterosacral Suspension

  2. Educational Objectives • This lecture will enable the participant to list and discuss the indications and complications of uterosacral suspension for apical defects. • This lecture will enable the physician to describe the surgical technique for uterosacral suspension

  3. Techniques • There are many techniques for reestablishing support of the vaginal apex • Sacrospinous ligament suspension • Iliococcygeus fascia suspension • Abdominal sacral colpopexy • Uterosacral ligament suspension

  4. Historical Perspective • Miller (1927) –bilateral suspension of the vaginal vault to the uterosacral ligaments • McCall (1957) –combined uterosacral suspension with an extensive culdeplasty • Jenkins (1997) –vaginal approach • Miklos (1998) –laparoscopic approach

  5. Anatomy • The uterosacral ligament is a fanlike structure originating at the sacrum and narrowing just proximal to its insertion at the cervix.

  6. Divisions of the Uterosacral Ligament (Campbell 1950) • Cervical –made up of smooth muscle with abundant blood vessels and nerve fibers • Intermediate—predominantly connective tissue, fewer nerves and vessels • Sacral—almost entirely composed of loose strands of connective tissue intermingled with fat

  7. Vascular structures adjacent to the Uterosacral Ligament • Sacral portion— the superior gluteal vein lies medial to the superior gluteal artery (post. branch of Hypogastric) Inferior gluteal vein and artery (anterior branch of Hypogastric) • Intermediate portion— the middle rectal artery is near the inferior margin( hypogastric and Inferior mesenteric) • Cervical portion— the coccygeal and accessory coccygeal artery (Branch of inferior gluteal)

  8. Proximity of the Ureter • Sacral portion---4.1 +- 0.6 cm • Intermediate portion—2.3 +- 0.9 cm • Cervical portion—0.9 +- 0.4 cm • Ischial spine—4.9 +- 2 cm

  9. Effect of Sutures • Sutures placed at the cervical portion exerted greater pressure on the ureter • Sutures placed in the sacral portion pulled out easiest

  10. The Intermediate portion • Provides strong suture fixation • Little pressure on the ureter • Greater distance from vascular structures

  11. Location is everything!! • Level of the ischial spine • One centimeter posterior to the anterior most palpable margin of the uterosacral ligament while held on tension

  12. Uterosacral Plication ? • We do not plicate the uterosacral ligaments • Narrowing of the upper vagina • Increased risk of ureteral obstruction?

  13. Abdominal and Laparoscopic Approach • Permits uterine preservation • Better for patients with shortened vagina? • Those with lifestyles involving heavy work • Prior prolapse surgery or procedures in the cul de sac • Suspicion of endometriosis • Severe uterine prolapse?

  14. Steps for Vaginal Uterosacral Suspension • Dissect cuff-enter peritoneum • Develop anterior and posterior endopelvic fascia • Three permanent double armed sutures on each side • 1.5 cm posterior to the ischial spine and1-2 cm apart toward the sacrum • Distal sutures placed laterally and proximal sutures medially through the fascia of the cuff (Shull 2000)

  15. Results • 82% had good support at two years • The anterior segment was more likely to fail • Anterior enterocele (Barber 2000)

  16. Complications • Ureteral obstruction—11% (Barber, 2000) • Cystoscopy with indigo carmine is indicated • Significant vascular involvement ? • Have a plan to handle it

  17. Conclusion • Uterosacral suspension is a safe and effective technique for the treatment of apical prolapse. • The gynecologic surgeon should be familiar with the vascular structures adjacent to the uterosacral ligaments and their proximity to the ureters at all levels.
