Purpose: Adjustable continence therapy (ACT) was developed to treat female stress urinary incontinence resulting from intrinsic sphincter deficiency by increasing urethral resistance. We evaluated the implantation procedure and assessed patient outcomes at our center.

Materials and Methods: The adjustable continence device consists of 2 silicone balloons on either side of the proximal urethra under the bladder neck, each attached to a titanium port buried in the labia to allow postoperative titration. Urodynamic assessment was done in 57 female patients in whom previous pelvic surgery had failed. Pad use and an incontinence quality of life questionnaire were evaluated before ACT implantation, postoperatively at 1,3,6 and 12 months, and annually thereafter. Patients recorded the overall impression and percent of improvement postoperatively based on the Patient Global Impression Index and a visual analog scale.

Results: Mean follow-up was 72 months (range 12 to 84). At 6-year follow-up in 29 patients mean pad use improved from 5.6 daily at baseline to 0.41 and intrinsic sphincter deficiency improved from 27.2 to 78.6 (p < 0.001). As measured on the visual analog scale, 68% of patients considered themselves dry. On the Patient Global Impression Index questionnaire 64% were very much improved, 23% were much improved and 13% were only minimally improved or unchanged. No patients considered themselves worse after the procedure. Complications necessitating device removal developed in 21.1% of patients.

Conclusions: Relative ease of insertion and the ability to tailor this therapy to individual needs makes this an attractive option for the challenging treatment for recurrent stress urinary incontinence due to intrinsic sphincter deficiency.

Editorial Comment

The authors review their experience with an anti-incontinence device comprised of two silicone balloons which is placed transvaginally and allows for postoperative titration to optimize long-term results. The authors were able to achieve a self reported dry rate in 68% of their patients with a mean follow-up of 72 months. No patient felt that the procedure made them worse.

When reading this article, many will remember the previous anti-incontinence device termed genitourinary spheroidal membranes which were placed approximately 20 years ago (1). The advantage of this contemporary device is the potential for less migration and the ability to postoperatively titrate. In the past, the genitourinary spheroidal membrane effect could be enhanced by placing more membranes spheres paraurethrally; consequently, on occasion there was some dislodgement with proximal migration of the device(s) into the retropubic space. This adjustable continence device is placed and first allowed to form a pseudo capsule prior to beginning the process of balloon adjustment to address the incontinence. This method seems to have limited the complication of dislodgement and optimized the results in this challenging population of patients with very low Valsalva leak point pressures (< 60 cm water). The device certainly looks appealing and very competitive with injectable therapy but only time will provide the answer whether it will achieve a high level of popularity.
