[Value of Transperineal Ultrasound in Short-term Evaluation of Pelvic Organ Prolapse after Transvaginal Mesh Implantation].

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(=0.000)and 0.235(=0.001),respectively.There were altogether 37 cases diagnosed inconsistently between TPUS and POP-Q,including 14(9.52%)cases of anterior compartment prolapse and 23(15.65%)cases of posterior compartment prolapse.TPUS diagnosed 32 more cases of prolapse than POP-Q,which included 13(8.84%)cases of anterior compartment prolapse and 19(12.93%)cases of posterior compartment prolapse.The incidence of hiatal ballooning in the TPUS prolapse group was significantly higher than control group(51.35% 33.94%,=3.950,=0.047).The incidence of levator avulsion showed no significant difference between the two groups(=1.000). Conclusions TPUS diagnosis of POP after TVM surgery has consistency with the POP-Q diagnosis of International Continence Society.TPUS can detect more POP cases,and thus it may act as a supplement for clinical diagnosis.Hiatal ballooning is associated with POP recurrence after TVM surgery.
