Cystoscopic autogenous fat injection treatment of vesicoureteral reflux in spinal cord injury.

| Abstract |
The purpose of this investigation was to determine the safety and efficacy of subtrigonal, periureteral injections of autogenous fat grafts for the treatment of vesicoureteral reflux. Seven patients (12 renal units) with vesicoureteral reflux were treated with subtrigonal autogenous fat injection. Fat harvesting was obtained from abdominal and thigh subcutaneous tissue. Approximately 2 ml of fat was injected beneath each ureteral orifice with a modified 10 Fr needle through a 23.5 Fr rigid cystoscope. Two of the seven patients experienced durable (six months) resolution of reflux. In three patients, reflux resolved but recurred within three months and another developed recurrent reflux within six months. In one patient with a periureteral diverticulum, proper positioning of the needle tip for effective fat injection was not possible, resulting in persistent reflux. Two of the five patients with persistent reflux demonstrated a diminished grade of reflux on follow-up cystography. Neither complications nor ureteral obstruction have been encountered. The subtrigonal injection technique can be used with autogenous adipose tissue to treat vesicoureteral reflux. Anatomic variation may determine those patients less likely to enjoy durable results. Clinical success and reabsorption of the fat cannot be predicted or controlled at the present time. The ideal periureteral bulking agent for the treatment of vesicoureteral reflux remains to be determined.
