Brief 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.

Outcome Measures

Primary Outcomes (1)

  • 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 Outcomes (4)

  • Stone free rate in weight's sub group

    3 months

  • Stone free rate in sub group depending on stone diameters

    3 months

  • Secondary procedure rate

    3 months

  • Serious and non serious adverse events

    3 months

Study Arms (2)

Extracorporeal shockwave lithotripsy

ACTIVE COMPARATOR

stone treatment using electroconductive technology

Procedure: extracorporeal shockwave lithotripsy

Flexible ureteroscopy

ACTIVE COMPARATOR

intra renal retrograde surgery with or without laser and stone extraction

Procedure: flexible ureteroscopy

Interventions

Flexible ureteroscopy will be use for 120 min max to treat renal stone. Laser, access sheath, baskets can be use to perform the technique.

Flexible ureteroscopy

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

Extracorporeal shockwave lithotripsy
