Summary: The LPDA and LAD have a moderate negative correlation. In patients with severe pelvic floor symptoms and extensive LAM injury, high LAD scores and low LPDA results were confirmed. The LPDA appears to be a very useful parameter in determining the severity of structural defects in the treatment of patients with pelvic floor disorders.

Summary: In this study, an efficient automatic segmentation model of pelvic floor muscles with MRI was proposed based on DenseUnet, which achieved muscle volume calculation and provided a reference for assessing pelvic floor function. The improved DenseUnet showed good segmentation performance, time efficiency, and accuracy compared to manual segmentation.

Summary: This study aimed to determine the relative activation of the pelvic floor muscles (PFM) during select yoga poses. The findings showed that the locust pose had the highest PFM activity, while the side angle, front plank, and side plank poses were optimal for improving endurance and neuromuscular control of the PFM.

Summary: This study assesses the appearance of musculo-fascial defects in women with pelvic floor dysfunction following first vaginal delivery. The results show that the symptomatic group has a significantly higher prevalence of muscular and fascial defects compared to the control group. Prolapse patients are more likely to have these defects.

Summary: The purpose of this study was to analyze the sensory and muscle functions of the pelvic floor in women with endometriosis, aiming to improve knowledge regarding pelvic floor muscle functions in these patients. The results showed that patients with endometriosis had pain and dysfunction of the pelvic floor muscles, indicating the need for early pelvic floor physiotherapy.

Summary: Maternal somatic birth trauma due to vaginal delivery is more common than generally assumed and can cause both psychological and somatic morbidity, some of it long-term and permanent. Recent developments in imaging diagnosis of maternal birth trauma and the use of key performance indicators can lead to greater awareness of birth trauma and improved outcomes for patients.

Summary: The objective of this study was to determine the thickness of the pubovisceral fasciculus and the area of the genital hiatus using three-dimensional perineal ultrasound in pregnant women in the 2nd trimester, and to analyze related clinical variables. The study found a significant correlation between maternal age and an increase in the area of the genital hiatus. Three-dimensional ultrasound of the pelvic floor at 20 weeks of gestation can be an effective and non-invasive tool for predicting labor development and potential perineal dysfunctions.

Summary: The risk of pelvic floor disorders in women is influenced by age, relative body weight, and pelvic canal size, independent of parity. In men, pelvic floor shape is mainly affected by body weight, with age playing a smaller role.

Summary: The study aimed to estimate the diagnostic test accuracy of magnetic resonance imaging (MRI) and pelvic floor ultrasound for levator ani muscle (LAM) avulsion in a general parous population. Results showed that ultrasound can be used as a triage test for LAM avulsion in parous women due to its high specificity, but it cannot substitute for MRI because of its lower sensitivity.

Summary: Dissection of the pelvic floor reveals its elegant simplicity, but confusion arises due to conflicting illustrations and lack of anatomical accuracy. To overcome this, we must focus on structures rather than words, reject theory-induced blindness, and revive century-old standards of anatomical illustration.

Summary: This study assessed the association between transperineal ultrasound findings and chronic constipation in women with endometriosis. The results showed that women with endometriosis and constipation had signs of pelvic floor muscle hypertonia on ultrasound, particularly in those with isolated ovarian endometriosis.

Summary: This study aimed to investigate changes in hiatal dimensions during active labor and their association with fetal descent and head position. The results showed a significant increase in the transverse hiatal diameter between the first and second stages of labor. Furthermore, the change in transverse hiatal diameter was associated with fetal descent but not with head position.

Summary: This study investigated the association between minimal levator ani hiatus area and age in female adults without pelvic floor dysfunction, and found significant differences among different age groups. Age was positively correlated with the minimal levator ani hiatus area.

Summary: The study aimed to obtain a finite element biomechanical model of pelvic organ prolapse (POP) in women and investigate the biomechanical properties and function of the pelvic floor supporting structures. Using Chinese Visible Human (CVH) images, a detailed 3D finite element model was reconstructed, including the cardinal ligament, uterosacral ligament, levator ani muscle (LAM), and perianal body. Simulating the Valsalva maneuver, stress, strain, and displacement of the supporting structures were calculated. The results demonstrated that the unbalance of abdominal pressure and pelvic floor supporting structures can lead to POP, providing a theoretical basis for pelvic floor anatomy, function, and obstetrical surgery.
