title: Neuromodulation of the superior hypogastric plexus: a new option to treat bladder atonia secondary to radical pelvic surgery?
abstract: BACKGROUND
  The aim of this study is to report on the impact of neuromodulation to the superior hypogastric plexus in patients with bladder atonia secondary to pelvic surgery.
  
  
  METHODS
  In 4 consecutive patients with bladder atonia secondary to pelvic surgery, we performed a laparoscopic implantation of a neurostimulator--LION procedure--to the entire superior hypogastric plexus.
  
  
  RESULTS
  Of the 4 reported patients, 3 are able to partially void or empty their bladder.
  
  
  CONCLUSIONS
  If the presented results could be obtained in further patients and maintained in long-term follow-up, the LION procedure to the superior hypogastric plexus could change the management of bladder function in patients with bladder atonia.
