Summary

To observe the clinical effects and make a comparative study between efficacy of electrical pudendal nerve stimulation (EPNS) and sacral neuromodulation (SNM) , evaluate the advantages of EPNS in the treatment of neurogenic non-obstructive urinary retention, and provide a new method for the treatment of the disease.

Conditions

  • Urinary Retention

Interventions

PROCEDURE

electrical pudendal nerve stimulation

The patient was positioned prone post-micturition. Long needles (0.40 Х 100 mm) were inserted perpendicularly, 1 cm bilateral to the sacrococcygeal joint, to a depth of 80-90 mm, eliciting sensations referred to the urethra or anus. The lower points, 1 cm bilateral to the coccyx tip, received oblique insertion of longer needles (0.40 Х 125 mm) toward the ischiorectal fossa (90-110 mm depth), inducing sensations precisely to the urethra. Connected to a G6805-2 Multi-Purpose Health Device, the ipsilateral needles created an electric loop, with the upper as anode and lower as cathode. Direct electrical stimulation (2.5 Hz, 25\~35 mA) for 60 minutes targeted the pudendal nerve, thrice weekly for a total of 4 weeks.

PROCEDURE

sacral neuromodulation

In the prone position, patients undergo sacral nerve root localization through MRI and CT fusion analysis. A 3D-printed sacral foramen puncture template is crafted for precision. Using local anesthesia, a 20G needle at a 60° angle enters the S3 sacral foramen along the template. A temporary stimulator, delivering square waves (14-35 Hz, 210-360 μs), tests motor and sensory responses to confirm accuracy. Self-fixating electrodes are then implanted, validated, and tunneled subcutaneously. External connection to a temporary stimulator provides a 4-week therapeutic experiential stimulation.Patients are administrated by antibiotics peri-operatively to prevent lead site infection.
