Transcutaneous electrical nerve stimulation in nerve-sparing radical hysterectomy: a retrospective cohort study

Postoperative voiding dysfunction is common after nerve-sparing radical hysterectomy (NSRH); therefore, we examined whether adjunct transcutaneous electrical nerve stimulation (TENS) could improve bladder management, pelvic floor muscle strength, and quality of life (QoL) in this population. A total of 78 NSRH patients from May 2023 to May 2024 were divided into conventional catheter management (control group, n = 39) and conventional management + TENS (intervention group, n = 39). Outcomes including urinary retention incidence, postvoid residual urine volume (PVR), catheter indwelling duration, intervention compliance, pelvic floor muscle strength grading, voiding function parameters, QoL scores, and safety were assessed. The intervention group demonstrated significantly lower urinary retention incidence, reduced PVR, and shorter catheter duration versus controls (all P 90% intervention compliance (P > 0.05). Post-intervention voiding parameters (FD, BC, MCC) improved more significantly in the intervention group (all P P P P > 0.05). TENS would significantly improves bladder function, pelvic floor muscle strength, and QoL in post-NSRH patients with a favourable safety profile, demonstrating substantial clinical value. This study tested whether transcutaneous electrical nerve stimulation (TENS) helps women recover bladder function after nerve-sparing hysterectomy for cervical cancer. 78 patients were split into two groups: Control group: Standard catheter care. Intervention group: Standard care plus TENS therapy (a non-invasive electrical stimulation method). Key findings: TENS reduced urinary retention, shortened catheter use, and improved bladder emptying. Patients receiving TENS had stronger pelvic floor muscles and better bladder control (measured by volume and pressure tests). Quality of life improved-fewer symptoms (e.g., discomfort) and better overall well-being. Safe treatment: Only mild skin irritation was reported, with no serious side effects. Conclusion: TENS is a safe, effective add-on therapy to help women regain bladder function and comfort after cervical cancer surgery.
