385 Urological Survey provement rate. Of the patients studied, approximately 18% required removal of the device. Of those cases that need explantation, 50% of the women still opted to be reimplanted within 12 months after the initial device removal. Presumably, secondary to position of the adjustment port, sexual activity was associated with a higher complication rate. An interesting technology, which is not overly dissimilar to the genitourinary spheroidal membrane, which had its greatest

... e of clinical exposure in the mid-1990s (1). Problems with the genitourinary spheroidal membrane at that time included the lack of ability for secondary and tertiary adjustments as well as the tendency of the device to float into non-therapeutic positions in the retropubic space. It seems that the adjustment port of this device, which is placed at the labia majora, may help anchor the support balloons and keep them from migrating to non-therapeutic positions as well as providing a method for adjustment. Perhaps these modifications will allow it to have a greater shelf life than that experienced by the genitourinary spheroidal membrane. Reference 1. Darson MF, Malizia AA, Barrett DM: Periurethral injection of the genitourinary spheroidal membrane. discussion 1874-5 Purpose: Dextranomer/hyaluronic acid injection of ureteral orifices is a popular option in the treatment of vesicoureteral reflux, with success rates ranging from 69% to 89%. We found only 1 study that followed patients beyond the initial postoperative voiding cystourethrogram, which describes a 96% success rate at 2 to 5 years but defines success as "nondilating" reflux. We examined our dextranomer/hyaluronic acid series to evaluate the long-term (1-year) outcome in children who had resolution of reflux on initial postoperative voiding cystourethrography. Materials and Methods: We retrospectively reviewed our dextranomer/hyaluronic acid experience from February of 2002 to December of 2005. We determined initial success on early (6 to 12-week) postoperative voiding cystourethrogram. We then evaluated long-term success by obtaining a voiding cystourethrogram at 1 year postoperatively in patients who were initially cured of reflux. In addition, success rates between the first and second halves of our experience were evaluated to account for surgeon experience and modification of technique.
