Pdf Summary

This study aimed to explore the relationship between forceps delivery and levator ani muscle (LAM) avulsion in patients with lower urinary tract symptoms and/or pelvic floor dysfunction. A retrospective analysis was conducted on 313 patients who underwent transperineal 4D ultrasound (TPUS) at the institution between November 2013 and December 2015. <br /><br />Out of the 313 patients, 48 (15.3%) had a history of forceps delivery, and 18 of them (37.5%) were found to have LAM avulsion. Of the remaining 265 patients who did not have forceps delivery, 47 (17.7%) also had LAM avulsion. The odds ratio for the presence of LAM avulsion in patients with a history of forceps delivery was determined to be 2.78, with a 95% confidence interval of 1.43 to 5.4 and a probability value of 0.0025.<br /><br />The study concluded that a history of forceps delivery was associated with a 3.6 times increased risk of LAM avulsion compared to patients without a history of forceps delivery. This association was assessed using TPUS.<br /><br />In terms of the methodology, all patients underwent TPUS in a supine position, after emptying their bladder and during rest, maximum Valsalva maneuver, and maximal contraction of the pelvic floor. LAM avulsion was diagnosed based on the presence of a clear LAM anomaly at its insertion or a urethra-levator gap greater than 24.9mm in the three central sections at the level of the minimum hiatal dimension.<br /><br />Overall, this study highlights the significance of LAM avulsion as a consequence of forceps delivery and its association with pelvic organ prolapse. TPUS was used as an effective tool for assessing LAM avulsion in this study.
