External Physical Vibration Lithecbole(EPVL) Versus Traditional Treatment for 4-10 mm Ureteral Stone

Ureteral Calculi Clinical Trial

Official title:
External Physical Vibration Lithecbole(EPVL) Versus Traditional Treatment for 4-10 mm Ureteral Stone: A Multi-center Prospective Randomized Controlled Trial

Clinical Trial Summary

The investigator aims to perform a prospective and randomized controlled trial evaluating the safety and efficacy of External Physical Vibration Lithecbole(EPVL) in treating 4-10 mm ureteral stone.

Clinical Trial Description

Patients with ureteral stones less than 10 mm, would receive observation for stone passage, not requiring immediate surgery. There are many studies evaluating the effect of Medical expulsive therapy in treating ureteral stones, including a-blockers, and calcium channel blockers. Most of shuties concluded that the benefit of a-blockers might be among those with larger (distal) stones. There is no good method for the removal of upper ureteral calculi, except drinking water and exercising.

Recently, a new extracorporeal physical vibrational lithecbole (EPVL) device named Friend-I EPVL (Zhengzhou Fu Jian Da Medical Instrument Co., Zhengzhou, China) has proven to be an effective treatment for upper urinary tract residual calculi. The device was approved by the Chinese food and drug administration in 2012. A Simple harmonic motion technology in multi-direction was applied. The Lateral acceleration was provided by the physical vibration device in the base through the harmonic vibration wave in the horizontal direction, which induces the urinary stone separate with the kidney or ureter, and expands a moving space for the stone. Meanwhile, an axial effect was produced to push the stone by the physical vibration device in the handle through the harmonic vibration wave in the multi- direction. So, we think that EPVL may be effective in treating ureteral stones. ;
