Clinical value of perineal ultrasound in diagnosis of pelvic floor dysfunction in women.

This study evaluates the clinical utility of transperineal 3D ultrasound in diagnosing pelvic floor dysfunction (PFD) and assessing uterine morphological changes in women. A total of 150 women with PFD and 100 healthy controls were examined. Measurements included anterior-posterior diameter, transverse diameter, and bladder neck and cervical mobility during Valsalva movement. No significant differences were found in demographic indicators between the groups. However, the observation group showed larger pelvic diaphragm fissures at rest, during tension, and anal contraction compared to controls, while anal levator muscle thickness was significantly lower. During Valsalva, bladder neck mobility and cervical descent were more pronounced in the PFD group, with statistically significant differences (p < 0.05). These findings indicate that transperineal 3D ultrasound provides an accurate, efficient, and detailed visualization of pelvic floor structures, aiding in diagnosis and treatment planning for PFD. The technique holds promise for broader clinical application.
