ABSTRACT
UNLABELLED: The flexible ureterorenoscopy coupled with photovaporisation LASER (USSR-L) for the treatment of kidney kidney is a modern tool whose place is under evaluation. METHODS: Its place has been assessed in France in 2010 by the Committee of urolithiasis of the French Association of Urology (CLAFU). A practice survey among 27 experts concerned the following decision criteria: comorbid patient's supposed nature of the calculation, anatomy of the urinary tract of the patient. This investigation has been proposed to calculate the size not exceeding 20mm, for a calculation of size greater than 20mm and for multiple calculations kidney. RESULTS: Fourteen experts responded. The criteria for the USSR-The first line were: morbid obesity (BMI>30), anticoagulation or anti platelet aggregation, calculations Hard (UH>1000, cystine stones), calculations within diverticular caliceal calculations below, the failure of a first treatment or the wish of the patient. CONCLUSION: The URS-SL was a first-line treatment validated regardless of size and number of kidney stones, when ESWL and PCNL were contraindicated or when their predictable results were poor (hard stones/morbid obesity/lower pole stones) or when stone access is difficult (intradiverticular). It was also the treatment of choice after the failure of a first treatment (ESWL/PCNL).
