Objective:
In this article, we describe a drainage guide attachment that allows trocar catheter placement for abscess drainage using the transvaginal or endorectal route under sonographic control. This drainage guide attachment has a central groove for catheter placement and a removable cover. Thus, the cover may be removed after catheter placement to allow the catheter to stay in place while the rest of the drainage guide attachment and the ultrasound probe are removed from the patient.
Conclusion:
Our findings indicate that a new sonography drainage guide attachment can be used for endorectal or endovaginal trocar catheter drainage of pelvic abscesses.
