Aim:
Pudendal neuralgia is a highly disabling entity with complex diagnostic and controversial treatment results. Surgical neurolysis has been shown to be the most effective treatment. Sacral root neurostimulation or posterior tibial nerve stimulation are used to rescue patients who either have not responded to surgery or have worsened after an initial improvement.
Methods:
Given the excellent visualization of the pudendal nerve during laparoscopic pudendal release, we propose to combine this procedure with neurostimulation, taking advantage of the possibility of in situ placement of the electrode. The abdominal cavity is accessed laparoscopically through four ports, and after identifying and releasing the pudendal nerve a neurostimulation electrode is placed next to the nerve and is connected to a generator located in a subcutaneous pocket.
Results:
This procedure has been performed in one patient with a satisfactory result.
Conclusions:
Laparoscopic pudendal release with neurostimulator prosthesis is an experimental technique that can be promising for the treatment of pudendal neuralgia.
