Transcutaneous Electrical Nerve Stimulation in Nerve-Sparing Radical Hysterectomy: Effects on Bladder Management and Quality of Life in Cervical Cancer

To evaluate the effects of transcutaneous electrical nerve stimulation (TENS) on bladder management, pelvic floor muscle strength, and quality of life (QoL) in patients undergoing nerve-sparing radical hysterectomy (NSRH) for cervical cancer. A total of 78 NSRH patients during May 2023-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 \[first desire to void (FD), bladder compliance (BC), maximum cystometric capacity (MCC)\], QoL scores (EORTC QLQ-C30: functional, symptom, and global health domains), and safety were assessed. The intervention group demonstrated significantly lower urinary retention incidence, reduced PVR, and shorter catheter duration versus controls (all P \< 0.05). Both groups maintained \> 90% intervention compliance (P \> 0.05). Post-intervention voiding parameters (FD, BC, MCC) improved more significantly in the intervention group (all P \< 0.05), with superior pelvic floor muscle strength grading (P \< 0.001). QoL assessment revealed lower functional domain scores and higher symptom/global health scores in the intervention group (all P \< 0.001). Safety analysis showed only mild dermal reactions in the intervention group, without significant between-group difference in complication rates (P \> 0.05). TENS significantly improves bladder function, pelvic floor muscle strength, and QoL in post-NSRH patients with a favorable safety profile, demonstrating substantial clinical value.
