title: Pelvic floor muscle functions are improved after successful transobturator vaginal mesh procedures.
abstract: To explore functional changes of pelvic floor muscle (PFM) after successful Perigee procedures.
  
  
  
  We retrospectively analyzed information from 145 women having achieved anatomic success, defined as <stage II cystocele according to the pelvic organ prolapse quantification (POP-Q) system. The investigated data included results from the POP-Q system and four-dimensional ultrasound at the preoperative and 12-month postoperative evaluations. The involuntary and voluntary PFM functions were, respectively, investigated during coughing and squeezing using the ultrasound parameters of the bladder neck distance (BND), bladder neck angle (BNA), genitohiatal distance (GHD), and genitohiatal angle.
  
  
  
  Postoperatively more women displayed normal involuntary PFM function in maintaining a stable bladder neck (preoperative vs. postoperative: 4.8% vs. 22.8%, P < 0.001) and genitohiatal (preoperative vs. postoperative: 16.6% vs. 30.3%, P = 0.008) locations upon coughing and could perform voluntary PFM contractions (preoperative vs. postoperative: 49.7% vs. 64.1%, P = 0.018). Compared with preoperative manifestations, less caudal displacement of the bladder neck indicated by smaller ranges of dynamic changes in BNA following coughing (preoperative vs. postoperative: 28° vs. 12°, P < 0.001), more cranial movement of the bladder neck indicated by larger values of changes in BND following squeezing (-0.26 vs. 0.06 cm, P < 0.001), and less reduction of genitohiatal size indicated by larger values of changes in GHD following squeezing (preoperative vs. postoperative: -0.95 vs. -0.63 cm, P = 0.027) were demonstrated postoperatively.
