Effects of Acupuncture on Hospitalized Patients with Urinary Retention

OBJECTIVE: The aim of this study was to investigate the effects of acupuncture on urinary retention and provide treatment suggestions. METHODS: A total of 113 hospitalized patients with urinary retention were included in this study. The GV20, CV6, CV4, CV3, ST28, SP6, and SP9 points were selected as the main acupoints. Acupuncture therapy was conducted for 30 minutes per session. The total number of treatment sessions was determined by the symptoms and the length of hospital stay. Bladder postvoid residual urine volume (PVR) was measured pretreatment and posttreatment by ultrasonic. Efficacy defined as spontaneous urination and a residual urine volume <50 mL was measured. RESULTS: The median number of acupuncture treatment sessions was 3 (range, 1–12 times). Acupuncture treatment significantly reduced the PVR (545.1 ± 23.9 mL vs 67.4 ± 10.7 mL; p < 0.001). Among the 113 patients, 99 (87.6%) patients were cured and 8 (7.1%) patients were improved of their urinary retention. The remaining 6 (5.3%) patients' urinary retention did not improve. The effective rate was 94.7%. There was significant difference in the efficacy rate between patients with one urinary catheterization and with two or more. Acupuncture treatment was not associated with side effects. CONCLUSION: Acupuncture is an effective and safe treatment option for urinary retention. Early application of acupuncture treatment should be considered in clinic, and repeated urinary catheter insertion and removal should be avoided. Our study suggests that a randomized controlled study with a large sample size to verify the efficacy of acupuncture for the treatment of urinary retention is warranted.
