Combining extracorporeal shock wave lithotripsy (ESWL) with extracorporeal physical vibration lithotripsy can improve ureteral stone expulsion, Chinese investigators reported in a late-breaking abstract session at the American Urological Association’s 2022 annual meeting.
Investigators randomly assigned 60 patients with ureteral stones to ESWL (control group) or ESWL combined with extracorporeal physical vibration lithotripsy (test group). The stone explusion rate was significantly higher in the test than control group at 2, 3, and 5 weeks after surgery, Han Yang, MD, PhD, of The Affiliated Hospital of Qingdao University, Qingdao, Shangdong, China, reported on behalf of his team. The test group experienced significantly quicker stone removal and pain relief and shorter hospitalization. The complication rate also was significantly lower in the test than control group.
According to the investigators, ESWL plus extracorporeal physical vibration lithotripsy appears safe and complementary.
