[Treatment of urinary stress incontinence using paraurethral injection of autologous fat].

The authors present the late results (greater than 1 year) in the treatment of urinary incontinence in 15 women with stress urinary incontinence and 5 men with post-adenomectomy incontinence using endoscopic injection of autologous fat tissue obtained by microliposuction. Good results were achieved in 23% of the cases with stress urinary incontinence and in 0% of those with post-adenomectomy incontinence. Although the results are disappointing, they are not very different from those obtained with teflon injection. Furthermore, the technique is simple, has no complications and it costs very little to obtain the autologous graft material. A historical review of free fat grafting and injection of liposuction fatty tissue is performed and the hypotheses that have been put forward recently relative to the fate of the fat graft are discussed.
