ABSTRACT
Objective To observe the patients after transvaginal mesh(TVM)implantation surgery by using transperineal ultrasound(TPUS),compare the diagnosis of pelvic organ prolapse(POP)by TPUS and clinical examination[according to the Pelvic Organ Prolapse Quantification(POP-Q)system published by the International Continence Society],and to explore the role of ultrasound in postoperative evaluation as well as the high-risk factors of post-surgery POP recurrence. Methods This is a retrospective study based on the POP-Q records and TPUS data sets of patients within 6 months after TVM surgery during September 2013 and November 2019.The diagnostic results of TPUS and POP-Q were compared.The incidences of hiatal ballooning and levator avulsion were separately compared between the TPUS group and the control group. Results A total of 147 patients were enrolled.The Kappa values between TPUS and POP-Q in the diagnosis of anterior and posterior compartment POP were 0.268(

The dimension of the levator hiatus is a possible predictor of pelvic organ prolapse (POP). This retrospective study investigated 360 women who went to urogynecological clinic for pelvic floor discomfort. Levator hiatus dimensions were obtained by three-dimensional transperineal ultrasound and results were compared between women with and without significantly objective prolapse (International Continence Society POP quantification, grade 2 or higher). Receiver operating characteristic (ROC) curve analyses were performed to determine valid screening index for detecting abnormal levator hiatus distensibility. Women with significantly objective prolapse had significantly higher levator hiatus dimensions than those without (all P < 0.001). ROC curve analyses confirmed that hiatal area (HA) of 19.5 cm during Valsalva maneuver can be used as single-screening index for abnormal levator hiatus distensibility with sensitivity of 0.80 and specificity of 0.70. In this study, we used a two-step method and achieved higher sensibility (0.80 vs. 0.87) without reducing specificity (0.70 vs. 0.71) compared with a single-screening index method. As a result, we suggest that HA ⩾ 19.5 cm during Valsalva maneuver is an indicator of abnormal levator hiatus distensibility in Chinese women and that the two-step method has higher sensitivity in detecting abnormal distensibility.
