[Update for the management of kidney stones in 2013. Lithiasis Committee of the French Association of Urology].

Since the publication of the latest recommendations of the Lithiasis Comity of the French Association of Urology (CLAFU) on the management of ureteral and renal stones, practices have evolved. This text provides an update for the treatment of kidney stones. It is especially the important advances in the field of laser-ureterorenoscopy that changed practices.

[Management of adult's renal and ureteral stones. Update of the Lithiasis Committee of the French Association of Urology (CLAFU). General considerations].

The Lithiasis Committee of the French Association of Urology (CLAFU) aimed to update the current knowledge about urolithiasis. This update will be divided into four parts: 1) general considerations; 2) the management of ureteral stones; 3) the management of kidney stones; 4) metabolic assessment and medical treatment of urolithiasis. Recent technicals advances helped the urologists to improve stones management: new extracorporeal shockwave lithotripsy (ESWL) devices, new flexible ureterorenoscopes, development of laser fragmentation.

[Place of the flexible ureterorenoscopy first choice for the treatment of kidney stones. Survey results practice committee of the AFU lithiasis completed in 2011].

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.

[Simultaneous bilateral percutaneous nephrolithotomy: Series of 60 cases].

Objective: Retrospective evaluation of the efficacy and morbidity of simultaneous bilateral percutaneous nephrolithotomy (SB-PCNL).

Methods: From January 1993 to July 2009, 60 patients have undergone SB-PCNL over a series of 1709 PCNL. Thirty men and 30 women, mean age 45 years old (13-78), were treated for bilateral renal stones (120 kidneys) of 1177 mm(2) (268-4972 mm(2)); 25 were complete staghorn stones.

Stone formation and pregnancy: pathophysiological insights gained from morphoconstitutional stone analysis.

Purpose: We examined whether stone composition in pregnant women reflects peculiar pathophysiological conditions.

Materials And Methods: We analyzed in detail the composition of stones from 244 pregnant women 17 to 44 years old and from 5,712 nonpregnant women in the same age range, as recorded between January 1991 and December 2007. Clinical features were also recorded.

[Characteristics of encrustation of ureteric stents in patients with urinary stones].

Introduction: The goal of this prospective study was to characterize ureteral stents encrustation in stone formers.

Material And Methods: We report the results of a study based on 658 double-J stents (412 men and 246 women) collected from patients with in situ urinary calculi. The mean age was 48.
