[Why is intussusception an antireflux mechanism?].
One of the aims of bladder substitution or augmentation using the intestine is to preserve renal function. If reflux impairs renal function, an antireflux mechanism should be attempted. Direct ureteroileal reimplantation with spatulation of the ureter is safer and carries a lower risk of stenosis. The antireflux mechanism is created by ileoileal or ileocecal intussusception without involvement of the ureter. Thus we can diminish the risk of stenosis and reflux at the same time.
