The fat was harvested from the low abdominal wall by micro-liposuction unit. The fat was injected at 4 and 8 o'clock position and the mean quantity was 15.7ml. Mean follow up was 16.2 months. Of the patients, 14 (29.8%) are cured, 5 (10.6%) are improved, and 28 (59.6%) are failed. Of the intrinsic sphincter dysfunction group, 6 (46.2%) are cured, 2 (15.4%) are improved, and 5 (38.5%) are failed. In contrast to the anatomic incontinence group 8 (23.5%) are cured, 3 (8.8%) are improved, and 23 (67.6%) are failed We conclude that the periurethral autologous fat injection is a safe, and low-cost, high benefit procedure in intrinsic sphincter dysfunction patients.
