Abstract:Objective To investigate the efficacy of external physical vibration lithecbole assisted ureteroscopy in treatment of lower calyceal calculi.Methods 184 patients with lower calyceal calculi were selected as subjects. Among them, 112 patients underwent ureteroscopy combined with external physical vibration lithecbole were considered as observation group, while other 72 patients underwent ureteroscopy combined with natural calculi removal were considered as control group.Results There were no serious complications in the process of calculi removal in both groups. The calculi removal rate of observation group was significantly higher on the day of operation than that of the control group, and the calculi clearance rate of observation group was all higher than that of control group at 1, 2 and 4 weeks after operation, and there was significant difference between the two groups (P < 0.01).Conclusion In vitro, external physical vibration lithecbole assisted ureteroscopy in treatment of lower calyceal calculi can significantly increase the calculi clearance rate and shorten the duration of calculi clearance, with high safety and satisfactory efficacy.
