As part of the DOMINO (Debates on Male Incontinence) project, the surgical procedures and outcomes were retrospectively analyzed in a total of 473 patients who received an artificial sphincter (AMS 800) between 2010 and 2012. Clinics that implanted at least 10 AMS 800 per year were defined as high-volume centers.
Sixteen centers had a mean rate of 9.54 AMS 800/y of which five clinics were identified as high-volume centers. They implanted significantly more double cuffs (55% vs 12.1%; P < .001), used the perineal approach significantly more often (78% vs 67.7%; P = .003) and chose larger mean cuff sizes (4.63 cm vs 4.42 cm; P = .002). With a mean follow-up of 18 months, the revision rate was significantly higher at low-volume centers (38.5% vs 26.7%; P = .037), urethral erosion being the main reason for revision. Social continence (0-1 pads/24 h) was achieved significantly more often in high-volume centers (45.5% vs 24.2%; P = .002).
Our study showed significantly better continence results and lower revision rates at high-volume centers, confirming earlier results that are still true in this decade. We, therefore, recommend surgery for male incontinence at qualified centers.
