**2.7 Results – AMS 800®**

Follow-up ranged from 27 to 132 months (mean 53.4 +- 21.4 months). There was a significant reduction in pad count from 4.0 +- 0.9 to 0.62 +- 1.07 diapers per day (*P<*0.001) leading to continence in 90%. Twenty patients (50%) were completely dry, and 16 (40%) required 1 pad per day. There was a significant reduction on the impact of incontinence decreasing from 5.0 +- 0.7 to 1.4 +- 0.93 (*P* \_0.001) in a visual analogue scale (VAS). Surgical revision rate was 20%. Preoperative urodynamics was useful to identify sphincter deficiency. Except by a tendency of worse results in patients with reduced bladder compliance (RBC), other urodynamic parameters did not correlate with a worse surgical outcome. (Trigo Rocha F, et al. 2008).
