    Abstract:
    AIM OF THE VIDEO/INTRODUCTION: The aim was to demonstrate our minimally invasive technique for excision of eroded transvaginal cervical cerclage suture through the bladder mucosa using a suprapubic-assisted transurethral approach. Transvaginal cervical cerclage is a common treatment for cervical insufficiency in pregnancy. Complications such as erosion are rare, as the duration of treatment is typically several months, with cerclage placement in the second trimester and complete removal prior to the onset of labor. Retained suture can lead to erosion through the vaginal epithelium and into other organs, as seen in our case. Our technique offers a minimally invasive approach to the excision of eroded transvaginal cervical cerclage suture through the bladder mucosa. METHODS: A narrated, stepwise video demonstration for removal of eroded cervical cerclage through bladder epithelium with suprapubic-assisted transurethral technique in a single patient was carried out. Key strategies for a successful outcome include: use of a Carter-Thomason device for suprapubic assistance in lieu of suprapubic trocar or suprapubic incision, use of rigid biopsy forceps for improved traction on the eroded suture, performing a methylene blue test for evaluation of vesicovaginal fistula after excision procedure. RESULTS: At her 2-week postoperative evaluation, the patient reported resolution of all symptoms. The Carter-Thomason incision was well healed, and postoperative urinalysis was negative for hematuria. CONCLUSIONS: A suprapubic-assisted transurethral approach can be used as a minimally invasive technique for excision of eroded transvaginal cervical cerclage suture through the bladder mucosa.
