Flexible urétéroscopy Versus Extracorporeal Shockwave Lithotripsy in Renal Calculi

Not Applicable

Completed

• Conditions: Extracorporeal Shockwave Lithotripsy, Flexible Ureteroscopy
• Interventions: Procedure: flexible ureteroscopy; Procedure: extracorporeal shockwave lithotripsy

• Registration Number: NCT01604304
• Lead Sponsor: Hospices Civils de Lyon

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.

Arm && Interventions

Group	Intervention	Description
Flexible ureteroscopy	flexible ureteroscopy	intra renal retrograde surgery with or without laser and stone extraction
Extracorporeal shockwave lithotripsy	extracorporeal shockwave lithotripsy	stone treatment using electroconductive technology

Primary Outcome Measures

Name	Time	Method
Stone free rate	Three months	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.

Secondary Outcome Measures

Name	Time	Method
Stone free rate in weight's sub group	3 months	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
Stone free rate in sub group depending on stone diameters	3 months	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
Serious and non serious adverse events	3 months	In each arm will be evaluate rate of adverse event, type, severity.
Secondary procedure rate	3 months	In each arm will be evaluate rate of secondary procedure needed to have the best stone free rate
