Ultrasound-guided laser treatment for fetal bladder outlet obstruction resulting from ureterocele

Abstract

In a case of severe bilateral hydronephrosis in a female fetus associated with ureterocele at 28 weeks, under local anesthetic, ultrasound-guided neodymium:yttrium-aluminum-garnet laser was used to perforate the ureterocele and successfully overcome the obstruction. There was no recurrence of obstruction, and renal function was normal postnatally. (Am J Obstet Gynecol 2003;188:1107-8.)
