Urolithiasis
-
Postoperative pain remains a significant problem and the individual variance in postoperative pain is not fully understood. In recent years, there has been focus on identifying risk factors predicting patients with high postoperative pain intensity or consumption of analgesics, which may facilitate an improvement in rehabilitation. This study evaluates the relationship between preoperative experimental pain assessment and postoperative pain and opioid consumption. ⋯ There were no other correlations between the preoperative sensory tests and postoperative pain or opioid consumption. This study showed a correlation between the preoperative electrical pain thresholds on the control-side and postoperative opioid consumption after percutaneous nephrolithotomy. Preoperative measurement of the electrical pain thresholds may, therefore, be useful as a screening tool to identify patients at high risk of postoperative pain.

Meta Analysis
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. ⋯ Only minor gastrointestinal adverse effect was reported on terpene compound drug use. The results suggest that terpene compound drug as MET is effective in augmenting spontaneous passage of ureterolithiasis. High quality large-scale RCTs comparing alpha-blockers and terpene compound drug are warranted to make a more definitive conclusion.
