How is the revealing mode of lithiasis?

- The lithiasis urinary disease mainly affects the upper urinary tract. - The most common mode of revealing is renal (nephritic) colic crisis. It is then a question of knowing how to recognize the signs of seriousness which can be vital prognostic. - However, urinary stones can be asymptomatic and discovered incidentally during imaging (ASP, reno-vesical ultrasound), or the assessment of chronic renal failure. - Low urinary tract lithiasis is restricted to highly targeted patient populations, such as patients with severe neurological conditions (particularly para- and quadriplegic patients). It always translates a bad bladder emptying which will have to be followed up and treated to avoid the recidivism (tendency to relapse).
