Percutaneous Nephrostomy for Treatment of Hydronephrosis of Pregnancy

Abstract
Hydronephrosis of pregnancy is a common phenomenon that rarely requires invasive intervention. We describe a young woman with markedly obstructive hydronephrosis of pregnancy causing forniceal extravasation who was treated successfully by percutaneous nephrostomy. The rationale of such intervention and its advantages over retrograde ureteral catheterization or stenting are discussed.
