[Urinary stone management at the time of its discovery].

Circumstances of diagnosis of urinary stones vary. Medical management is performed either in emergency for acute or serious symptoms, or delayed. Renal colic is the most typical clinical form. The emergency analgesic treatment is well established. After sedation of the pain, radiological study (plain film and ultrasound of the abdomen) may be supplemented by abdominal computerized tomography which is the best exam for the diagnosis of urinary stone and its impact. In complicated cases urological drainage is performed in emergency. If needed the urological treatment of the urinary stone is performed secondarily according to the French recommendations. A metabolic evaluation and dietary survey are required for each patient to identify and avoid the risk of recurrence. Some stone formers or complex patients must be followed in nephrology.
