Introduction: Transcutaneous electrical acupoint stimulation (TEAS) has been proposed for postoperative urinary retention (POUR). This meta-analysis evaluated the effect of transcutaneous electrical acupoint stimulation in preventing postoperative urinary retention.
Methods: Databases were searched until February 6, 2023. Randomized controlled trials (RCTs) about transcutaneous electrical acupoint stimulation for preventing postoperative urinary retention were included. The primary concern was the incidence of postoperative urinary retention, with post-void residual urine volume as a secondary outcome.
Results: Fourteen studies with 2865 participants were identified. Transcutaneous electrical acupoint stimulation reduced the incidence of postoperative urinary retention (RR = 0.44, 95%CI = 0.33 to 0.58, P < 0.00001) and decreased the post-void residual urine volume (MD = -75.41 mL, 95%CI = -118.76 to -32.06, P = 0.0007). The preventive effect on postoperative urinary retention was found in patients receiving anorectal, gynecologic, orthopedic and biliary surgery, but not urinary surgery.
Dilatational- and continuous-wave transcutaneous electrical acupoint stimulation had a great outcome in preventing postoperative urinary retention. Intraoperative transcutaneous electrical acupoint stimulation, preoperative and intraoperative transcutaneous electrical acupoint stimulation, and postoperative transcutaneous electrical acupoint stimulation were beneficial, and transcutaneous electrical acupoint stimulation was more beneficial when compared with sham transcutaneous electrical acupoint stimulation and blank control.
Conclusions: TEAS could prevent postoperative urinary retention.
