Flexible urétéroscopy Versus Extracorporeal Shockwave Lithotripsy in Renal Calculi

Flexible urétéroscopy Versus Extracorporeal Shockwave Lithotripsy in 5 to 20 mm Renal Calculi, Efficacity Prospective Randomized Trial

Flexible ureteroscopy is a recent procedure to treat renal stone. Extracorporeal shockwave lithotripsy was the gold standard treatment for calculi between 5 and 20 mm. In literature, the two procedures are available to treat these stones with a good stone free rate. There is no prospective randomized study comparing these two treatments. Our study will define with a good level of evidence which technique is the best with regard to the stone free rate, secondary procedure rate and adverse effect.
