Surgical treatment of intrinsic urethral dysfunction: injectables (fat).

Injection of autologous fat has been used for many years to correct cosmetic surgical defects. More recently, autologous fat injection has been applied to the treatment of urinary incontinence. The background and technique of periurethral fat injection are described in this article. The technique is safe, and preliminary results are encouraging in women with intrinsic sphincter deficiency. Long term follow-up and comparative trials will determine the ultimate utility of periurethral fat injection for the treatment of women with intrinsic sphincter deficiency.
