Abstract:
Objective Dynamic MRI with rectum injectionis employed to assess female spastic pelvic floor syndrome of anorectal morphology and function in relation to various pelvic compartment abnormalitiesin female outlet obstruction constipation.
Methods Dynamic MRI was performed in 53 female patients(14-78 years of age, with a mean age of 52.7±15.8 years)with clinical diagnosis of spastic pelvic floor syndrome.The homemade highly conformable sacculus was inserted into the rectum to simulate stool. The relevant measurements were then obtained during straining before and after rectum injection.
Results Among the 53 female patients with spastic pelvic floor syndrome, 24 patients(45.3%) have multifocal disorders involving more than one compartment.The difference in the anorectal angles before and after rectum injection was not significant(χ2=0.603, P > 0.05). Differences in the cystocele, vaginal or cervical prolapse, rectocele, and descending perineum before and after rectum injection were significant.
Conclusion Using dynamic MRI with rectum injection allows for the accurate evaluation of the anorectal morphology and function related to various pelvic compartment abnormalitiesin female spastic pelvic floor syndrome; thus, this method is proved valuable in the diagnosis and treatment of female spastic pelvic floor syndrome.
