Clinical Trial Summary

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.

Intervention

Procedure:
flexible ureteroscopy
Flexible ureteroscopy will be use for 120 min max to treat renal stone. Laser, access sheath, baskets can be use to perform the technique.
extracorporeal shockwave lithotripsy
The lithotriptor is use with 1,1 Hz frequency and stop when patient get 1000 joules of energy or if there is a problem with tolerance of this treatment or if stone is broken

Outcome

Type Measure Description Time frame Safety issue
Primary Stone free rate Rate of stone free patient or patient with residual fragment = 3 mm, 3 months after the treatment evaluated, will be compare. This outcome is measured with a tomodensitometry and compares with pre treatment exams. Three months
Secondary Stone free rate in weight's sub group Each arm wil be divise in 3 sub group based on body mass index (20 to 25, 25 to 30, 30 to 35). We'll compare rate of efficacity in each sub group 3 months
Secondary Stone free rate in sub group depending on stone diameters Each arm wil be divise in 3 sub group based on calculi diameter (5 to 10mm, 10 to 15 and 15 to 20). We'll compare rate of efficacity in each sub group 3 months
Secondary Secondary procedure rate In each arm will be evaluate rate of secondary procedure needed to have the best stone free rate 3 months
Secondary Serious and non serious adverse events In each arm will be evaluate rate of adverse event, type, severity. 3 months
