[Periurethral injectables in the treatment of urinary incontinence caused by sphincter insufficiency].

OBJECTIVE: Periurethral injectables are among the multiple therapeutic options that urologists have to correct female stress urinary incontinence currently. The philosophy of periuretrhal injectables action mechanism has always been the same, to increase urethral walls coaptation or pressure, which is pathologically diminished.

METHOD/RESULTS: New surgical techniques, approaches and instruments have been appearing with time. Historically various injectable materials have been used, each one with its advantages and disadvantages.

CONCLUSIONS: The role of periurethral injectables in the treatment of female stress urinary incontinence is limited. The efficacy of the procedure is low and they would have little room in the treatment of female stress urinary incontinence if it were not because of its minimally invasive condition in patients with intrinsic sphincter insufficiency, whom would require more aggressive procedures otherwise also of uncertain results, or to remain untreated.
