BACKGROUND: Solidity and elasticity are the two main biomechanical properties of pelvic tissues involved in surgical cure of @entity3577 -prevertebral, pectinate, and sacrospinal ligaments, @entity530 , vaginal tissue. We report data in the literature and personal studies concerning these autologous biological tissues. MATERIAL AND METHODS: The resistance of pelvic tissues was tested on 29 cadavers. Measurements were also made on two 2-cm samples of vaginal tissue obtained during vaginal route surgery for prolapse cure in 20 menopaused @entity1 . Stress tests were conducted to determine resistance and level of @entity397 . RESULTS: There was a wide variability in ligament resistance, ranging from a minimum of 22 Newtons to a maximum to the order of 200 Newtons. Results varied greatly from one @entity1 to another and also between the two sides in the same @entity1 . The prevertebral ligament exhibited the greatest resistance. The pectinate ligament was significantly more resistant than the sacrospinal ligaments and the @entity530 . There was a significant relationship between the subjective assessment of ligament quality and objective measurements of resistance. For vaginal tissues, resistance varied greatly from 12 Newtons to a maximum to the order of 76 Newtons. Flexion values ranged from 14 to 130 Newtons. CONCLUSION: Our findings illustrate pelvic tissue failure observed in @entity1 with @entity3577 . Individual maximal resistance of the pelvic ligaments is vary variable, between ligaments and between subjects, and even between sides in a given subject. Pelvic ligaments used for cure of @entity3577 are moderately resistant with wide interindividual variability. The mechanical properties of vaginal tissue are also very variable, illustrating why these tissues may exhibit a certain resistance against dissociation when exposed to loading but much less resistance when exposed to traction by a surgical suture. These findings suggest a revision of classical surgical procedures.
