Pelvic abscesses: transvaginal US-guided drainage with the trocar method.

The effectiveness of the trocar technique of catheter placement for transvaginal sonographically guided drainage of pelvic abscess was assessed in seven women who presented with pelvic pain, fever, and presumed pelvic abscess. Endovaginal ultrasound was performed to document fluid collection before drainage. All procedures were performed in less than 1 hour, without complications. Catheters were left in place for 1-3 days. Catheter placement was curative in six of seven patients (86%).
