Objective To investigate the consistency and stability of two types of pubococcygeal line (PCL) determined by dynamic MRI used in evaluating pelvic organ prolapse (anterior and apical compartments).The first type of PCL was measured from the inferior pubic symphysis to the tip of coccyx (PCLtip) and the second was to the sacrococcygeal joint (PCLjnt).Methods Dynamic MRI changes of 50 female patients who were diagnosed with pelvic organ prolapse by pelvic organ prolapse quantification were retrospective reviewed.Chi-square test was used to compare the staging of each pelvic compartment (anterior,apical) with the two PCLs.The lengths and the degree of the oblique angle of the two PCLs during the rest and straining were compared using a paried t test.Results Agreement of PCLjnt with PCLtip was 96% (48/50) for anterior compartment and 94% (47/50) for apical compartment.There was no difference between the two PCLs in staging of each pelvic compartment (anterior,apical)(x2 values were 2.000 and 3.000,P values were 0.368 and 0.223).The length of the PCLtip at rest and straining was (10.1±0.8),(10.2± 0.8) cm respectively and the result was statistical significance (t=-2.339,P=0.023).Twenty patients (40%) in the 50 pelvic organ prolapse patients demonstrated a shortening of the PCLtip,while the rest including 30 patients (60%) was longer.The oblique angle of the PCLtip at rest and straining was 22°±6° and 18°±11° respectively(t=3.490,P=0.001).The length of the PCLjnt at rest and straining were (11.2±0.8) and (11.2± 0.8)cm respectively(t=-1.845,P=0.071).The oblique angle of the PCLjnt at rest and straining were 29°±6° and 26°± 10° (t=2.836,P=0.007),but the degree of PCLjnt's oblique angle had a mild fluctuate compared with the PCLtip.Conclusions PCLjnt and PCLtip have the equal level in staging of anterior and apical pelvic organ prolapse.Meanwhile the oblique angle and the length of PCLjnt illustrated the better the stability.
