Abstract:
0. 05) . The muscular fiber density of levator ani muscles in SUI and POP groups was decreased, fibers were arranged in disorder and separated by large quantities of dense connective tissues with infiltrating inflammatory cells. The muscle fiber fascicles showed obvious grouped denervative atrophy, fiber type grouping and angular in shape. And also there was myopathic degeneration such as centrally located nuclei, peripheral phagocytosis and vacuolated necrosis. Conclusions There are both neurogenic and myopathic alterations in levator ani muscle's structure in patients with SUI and POP. The presence of both acute and chronic abnormalities indicates that the weakness of pelvic floor is a consequence of prolonged denervation.
