Background: Whether acupuncture therapy contributes to preserving residual renal function (RRF) remains largely unknown. This case series demonstrated the potential beneficial effects of acupuncture for preserving RRF in five patients with end-stage renal disease undergoing hemodialysis (HD) treatment.
Participants: HD patients received eight sessions of weekly 30 min interdialytic acupuncture (Inter-A) at ten selected acupoints, namely Yintang (GV29), Yingxiang (LI20), Shuijin (Tung's Acupuncture), Lianquan (CV23), Shangqu (KI17), Tianshu (ST25), Siman (KI14), Hegu (LI4), Zusanli (ST36) and Sanyingjao (SP6). Residual urine volume (rUV) and residual glomerular filtration rate (rGFR) were recorded once every two weeks Outcomes: Changes in rUV and rGFR were calculated using 24 h urine collection data to assess RRF. Variations in hemoglobin, urea Kt/V and serum albumin levels were measured monthly to evaluate HD adequacy.
Results: After eight Inter-A sessions, the mean[standard deviation] rUV and rGFR increased from 612[184] ml/day and 1.48[0.94] ml/min/1.73 m2 at baseline to the peak of 803[289] ml/day and 2.04[1.17] ml/min/1.73 m2 at 2- and 4-week follow-up, respectively. The mean percentage difference increased by 31% in the rUV and 37% in the rGFR. Routine measurements of HD adequacy also showed improvements.
Conclusions: Acupuncture might be an optional add-on treatment for HD population with poor control of water; however, further well-designed controlled trials are warranted.
