Objective To investigate the therapeutic effect and safety of temporary electrode and Tined Lead electrode in sacral neuromodulation evaluation. Methods Thirty-four patients with chronic pelvic floor dysfunction were divided into temporary electrode group (n=16) and Tined Lead electrode group (n=18), and temporary stimulation tests were performed after electrode placement. The conditions of voiding and defecation were recorded every day, and related urodynamic parameters were measured. Results The symptoms improved in 43% patients with urgent incontinence and 35% patients with urinary frequency and urgency, and 10% patients with urgent incontinence or urinary frequency and urgency were cured. There were significant differences in the rates of self-perceived improvement of voiding and defecation between temporary electrode group and Tined Lead electrode group (32.2% vs 38.2%, P<0.05). There was no significant difference in the rates of improvement of pain and voiding volume in patients with pelvic floor pain syndrome and interstitial cystitis between two groups (P>0.05). Electrode shift took place in 4 patients in temporary electrode group and in 1 patient in Tined Lead electrode group. Conclusion Sacral neuromodulation is a safe, minimally invasive and effective method for treatment of chronic pelvic floor dysfunction, and Tined Lead electrode may prevent the electrode shift, increase the rate of success, and improve the therapeutic effect.
