[The efficacy of external physical vibration lithecbole in the assistant treatment of the upper urinary tract residual stones: a meta-analysis].

Objective: To determine the clinical effect of Friend-Ⅰ External Physical Vibration Lithecbole (EPVL) by Meta-analysis. Methods: Pubmed, Embase, Medline, Cochrane Library, Chinese National Knowledge Infrastructure were searched for clinical trials comparing EPVL with the conventional treatment. The quality of included studies was assessed and Meta-analysis was conducted by Review Manager 5.3 software. Results: Five randomized or Quasi-randomized controlled trials met the inclusion criteria. The first day stone expulsion rate of EPVL group was superior to the control group (OR=4.95, 95% CI: 3.35-7.32, P<0.000 01). Both one-week (OR=3.13, 95% CI: 1.95-5.04, P<0.000 01) and two-week stone free rate (OR=4.50, 95% CI: 2.02-10.00, P=0.000 2) were statistically higher in the EPVL group than that in the control group. No severe adverse event occurred during the follow-up. Conclusions: Our study suggested that EPVL could be the effective treatment for upper urinary tract residual stone. However, more high quality randomized controlled trials are needed to better affirm this.
