Lithiase et grossesse

Diagnosis of urolithiasis during pregnancy is a common condition not more frequent than in non pregnant women. Ultrasonography will be the main tool of diagnosis. If sonography fails, ionizing radiation will be used only if MRI is not available. One must take care of the mother and the foetus because preterm delivery is increased in case of lithiasis during pregnancy. Conservative treatment is favoured taking care of specific contraindications of medical therapy related to pregnancy. In case of complications, drainage of the urinary system by retrograde or antegrade approach will be considered. Endoscopic treatment is realized only in case of failure of drainage or in the post-partum with etiologic investigations.
