Abstract
INTRODUCTION: The obstruction of the urinary tract by calculi at the narrowest anatomical areas leads to impaired drainage and severe pain. The aim of this study was to evaluate a new technology, extracorporeal physical vibrational lithecbole (EPVL) combined with tamsulosin, as a treatment for distal ureteral calculi (DUC). MATERIALS AND METHODS:Between July 2013 and July 2014, 672 patients diagnosed with DUC were randomly divided into three groups; a group receiving EPVL plus 0.4 mg oral tamsulosin daily (PO qd) (experimental group, n = 236), a group receiving 0.4 mg tamsulosin PO qd (n = 222), and a group receiving EPVLonly (n = 214) (control groups). RESULTS: There were no significant differences in general characteristics between the three groups. Stone diameters ranged from 0.32 to 1 cm. In the EPVL plus tamsulosin group, 60.1% of patients showed detectable fragment expulsion at 48 hours, and 91.1% were stone free at 7 days. Compared with the two control groups, these rates were significantly higher (EPVL group was 0% and 50.5% and medical expulsive therapy group was 0% and 50.0%, p < 0.05). The stone-free rates were similar in the three groups 2 weeks later (94.5%, 93.6%, and 93.5%; p > 0.05). Patients in the EPVL plus tamsulosin group achieved similar stone-free rates compared with the other two groups, but the speed of the stone expulsion was quicker for both sexes and all age groups (about a week; p < 0.05). CONCLUSION: This indicates that EPVL plus tamsulosin could be used as an effective, but faster treatment option for patients with DUC, alleviating the symptoms of DUC in a shorter period of time.
