ProACT for Urinary Incontinence

ProACT is an extra urethral bulking system made of a silicone balloon connected with a dual lumen tubing (12–14 cm) to a titanium scrotal port that allows the postoperative adjustment (Fig. 6.1). It was introduced in the European market in 2000 as the first non-circumferential compressive device. The continence mechanism is guaranteed by a bilateral compression of the urethra, augmenting maximum urethral closure pressure (MUCP). In a study by Reuvers et al. this mechanism was demonstrated in a cohort of 23 successfully implanted patients in which a significant increase in MUCP from 58 cmH2O to 79 cmH2O was observed [1].
