To assess the efficacy and safety of External Physical Vibration Lithecbole (EPVL) for the treatment of residual stone after retrograde intrarenal surgery (RIRS).A total of 173 patients (128 male and 45 female) were selected for the study. All the patients had residual fragments after RIRS for the renal or upper ureteral stones. They were prospectively randomized into two groups, one received EPVL one week after RIRS (group ER), another only underwent RIRS as a control (group CR). Stone size and location, stone free rate, and the complications were compared.Of 173 cases, there were 87 (66 male and 21 female) in ER group and 86 (62 male and 24 female) in CR group. The stone free rate (SFR) in ER and CR group at 2 weeks after RIRS was 52.9% and 31.4%, at 3 weeks 71.3% and 51.2%, and at 5 week 89.7% and 59.3%, respectively (all P <0.05). The hematuria incidence at 5 week after RIRS was 3.4% in ER compared to 20.9% in CR group (P <0.05). The positive urine leukocytes in ER and CR group at 3 week after RIRS was 4.6% VS 19.8%, at 5 week was 3.4% VS 11.6% (P<0.05).EPVL supplementary to RIRS was more effective than RIRS alone in terms of stone clearance speed, SFR and the patients compliance.
