Angioli and colleagues (2008) stated that in recent years they used a lot of bulking agents including bovine collagen, Macroplastique (polydimethylsiloxane), calcium hydroxylapatite, ethylene vinyl alcohol copolymer, dextranomer in the treatment of urinary incontinence. Urethral injection have success in 40 % to 90 %. These investigators asserted that Macroplastique is the most effective and safe on the basis of literature data and of their experience. This surgical procedure, in fact, has good percentage of success in accurately selected patients. In the authors' experience, Macroplastique can also be used in oncological patients, in elderly women, in patients with important co-morbidity and with high surgical risk with good objective and subjective results.
