Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tested two types of electrical nerve stimulation to help people who cannot fully empty their bladder due to nerve damage. 70 adults with non-obstructive urinary retention received either pudendal nerve stimulation with long needles or sacral neuromodulation. The main goal was to see how much the leftover urine in the bladder decreased after treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
electrical pudendal nerve stimulation (EPNS) and sacral neuromodulation (SNM)
What this could lead to
If successful, this could offer a non-drug, non-surgical option to help people with nerve-related urinary retention empty their bladder more completely.
What could go wrong
This is a small, completed study with 70 participants, so results may not apply to everyone. The procedure involves needles and electrical stimulation, which may cause discomfort or not work for all patients.

Inclusion Criteria: * Non-mechanical obstructive urinary retention occurs following relevant neurological system disorders (spinal cord injury, spina bifida，myelitis, cervical/thoracic disk disease, lesion following spinal anesthesia/spine surgery,lumbar/sacral spine intervertebral disc diseases, spinal stenosis, iatrogenic pelvic nerve lesions, sacral agenesis, peripheral neuropathy due to diabetes mellitus). * With normal upper urinary tract function. * Other therapies and medications potentially affecting the assessment of this therapy have been discontinued for at least two weeks before the interventional procedure. * Patient with good compliance who is capable of cooperating with the follow-up requirements Exclusion Criteria: * Patients with any suprapontine and pontine lesions * Pregnant or lactating women * Individuals whose symptoms show significant improvement after pharmaceutical and adjunctive therapy * Individuals with concurrent acute or chronic prostatitis, prostate cancer, or conditions such as bladder neck stenosis, urethral stricture, or urethral injury * High pathological risk factors (e.g., lymph node metastasis, resection margin involvement, bulky tumors) * Individuals with concomitant obstructive urinary retention
