Can J Urol. 2026 Apr 15;33(2):309-323. [doi: 10.32604/cju.2026.070466](https://pubmed.ncbi.nlm.nih.gov/42086350/) ## Abstract Objectives: The external physical vibration lithecbole (EPVL) is a new device. It is clinically employed to improve the stone-free rate (SFR). However, it is not widely accepted in clinical practice due to the lack of high-level evidentiary support and a standard protocol. This study aimed to evaluate the effectiveness and safety of external physical vibration lithecbole (EPVL) as an adjunct to extracorporeal shock wave lithotripsy (ESWL) or retrograde intrarenal surgery (RIRS) for upper urinary tract stones. Methods: We systematically searched PubMed, Web of Science, Embase, the China National Knowledge Infrastructure (CNKI), and the Cochrane Library from inception to 13 January 2026, for randomized controlled trials (RCTs) comparing EPVL plus standard care with standard care alone, and we pooled relative risks (RR) with 95% confidence intervals (CI). Results: Nine RCTs involving 1418 patients were analyzed. Compared with standard care alone, EPVL significantly increased early stone-free rates at about 1 week (RR 1.44, 95% CI 1.18-1.77, p < 0.001) and 2 weeks (RR 1.40, 95% CI 1.20-1.63, p < 0.001) after ESWL or RIRS, with greater benefit for lower-pole (RR 1.56, 95% CI 1.25-1.96, p < 0.001) and renal pelvic stones (RR 1.54, 95% CI 1.10-2.14, p = 0.01). EPVL was associated with a lower rate of overall complications (RR 0.58, 95% CI 0.46-0.73, p < 0.001); specifically, it was linked to lower risks of hematuria (RR 0.64, 95% CI 0.48-0.86, p = 0.002) and urinary tract infection-related findings (RR 0.28, 95% CI 0.14-0.57, p < 0.001). Conclusions: Adjunctive EPVL improves short-term stone clearance after ESWL or RIRS without adding measurable risk and may also be associated with a reduced incidence of complications. Where available, EPVL can be considered as a non-invasive option to enhance fragment clearance, particularly for lower-pole renal stones. Further multicenter trials are needed to confirm long-term outcomes and generalizability. ## Comment Peter Alken This is what I expected from the previous publication on the device. I do not think that “Further multicenter trials are needed to confirm long-term outcomes and generalizability.” Peter Alken 0 #### Comments No comments made yet.
