Unilateral huge hydronephrosis necessitating fetal interventions.

Abstract

Fetal intervention for obstructive uropathy was first performed at the University of California, San Francisco in 1981 [1]. Since then diagnostic criteria for fetal intervention have been laid down to assist in proper patient selection [1-3]. Unilateral fetal hydronephrosis doesn’t require prenatal intervention; but prenatal intervention might be required in selected cases, especially when hydronephrosis compresses adjacent organs [4]. A 26-year-old pregnant woman was referred to our prenatal center for a fetal abdominal cystic mass with severe oligohydramnios detected at 27th week of gestation. Prenatal scan showed a single male fetus with a cystic avascular mass (74×84 mm) located in the left hemi abdomen pushing left hemi diaphragm (Fig. 1).
