title: Management of acute hydronephrosis of pregnancy by ureteral stenting: risk of stone formation.
abstract: Acute hydronephrosis of pregnancy has long been managed with ureteral stenting. Although many articles have been published recently concerning stent incrustation none has addressed the etiology. We report a case of accelerated incrustation due to the hypercalciuric state of pregnancy. We propose conservative management with hydration, calcium restriction and close monitoring for infections and stone debris. Antibiotic suppression and stent changes should not be used routinely but rather they should be individualized.
