title: [Management of renal stones].
abstract: The management of renal stones needs a recent and good quality imaging. Contrast medium injection is optional. Extracorporeal shockwave lithotripsy (ESWL) is the most common treatment of renal stones. ESWL is indicated as first line treatment for less than 1.5cm stones. The stone-free (SF) rate at 3 months of ESWL is 70-80%. Results of ESWL for stones with more than 1000UH density or located in the lower calyx are poor. Flexible ureteroscopy (URS) is indicated in case of ESWL failure or for hyperdense, 1-2cm stones. The SF rate of flexible is 80%. Percutaneous nephrolithotomy is indicated for complex or more than 2cm stones. Asymptomatic and non infected stones, especially if located in the lower calyx, do not need urological treatment but must be followed up. In all cases, renal stones needs a metabolic evaluation and treatment, and annual follow-up.
