Repeated lipoinjections for stress urinary incontinence.
A total of 30 women with stress incontinence underwent periurethral injection of autologous fat under spinal anesthesia. The fat was harvested from the abdominal wall by liposuction. Preoperative evaluation consisted of history, physical examination, and urodynamic evaluation. For study purposes, some patients also underwent bladder and urethral ultrasonography and magnetic resonance imaging studies. The first 13 patients received a single periurethral lipoinjection, and the following 17 patients received sequential injections when needed at 3-month intervals. Results were assessed by subjective questionnaire performed at 3 and 12 months. All patients had intrinsic sphincteric deficiency. Of the first group, there were only four patients (31%) cured after 1 year of follow-up. On the other hand, in the group that received repeated injections, there were 11 patients (64%) cured with a mean of two injections at 1-year follow-up. Our results show that this procedure warrants continued clinical investigation because it may be useful in selected cases of urinary stress incontinence.
