Terpene compound drug as medical expulsive therapy for ureterolithiasis: a meta-analysis.

The aim of this study is to investigate the efficacy of terpene compound drug (pinene, camphene, borneol, anethole, fenchone and cineol in olive oil) in facilitating spontaneous passage of ureteral calculi through meta-analysis of randomized controlled trials (RCT). Systematic literature search on MEDLINE, EMBASE, OVID, Science Direct, Proquest, Google scholar, Cochrane Library databases and reference list of related literatures were done without language restriction. RCTs on ureterolithiasis medical expulsive therapy (MET) that compare terpene compound drug versus placebo/control group or alpha-blockers were identified.
